Since the 2008 BMW M3 of Project Maximus fame will be getting a 211 boost in horsepower it follows that a boost in stopping power is needed. We chose AP Racing's brand new Radi-CAL™ big brake system designed by STILLEN to clamp down the speed generated by the ESS Supercharger under the hood and the Ohlins Road and Track coil-over suspension at the four corners.
Our E92 M3 transformation is running on all cylinders, so to speak. Parts are flooding in from all corners of the world and we're well into the installation procedure. In this installment of Project Maximus we'll take a quick break from the ESS Supercharger installation and focus on the Ohlins suspension upgrades. As the old saying goes, power is nothing without control.
Project Maximus is well under way. We decided our first order of business would be the most complicated part of the project, the ESS supercharger installation. The supercharger really is the heart of the beast, and all of the other enhancements that we'll be adding to the black 2008 BMW M3 are designed to keep all that power under control.
Winter storm Maximus brought heavy snow and travel delays throughout the Midwest and Northeast. It also brought us a 2008 BMW M3 coupe and along with it a project that can only be described as epic. The dark M3 will be transformed from a competent foot soldier into an all-conquering supercharged gladiator.
Do not do this at home, trained professionals at work! Joking aside, a quick lesson for potential DIYers: think long and hard before tackling suspension work. We just completed a full suspension rebuild on a well worn, 182k mile E36 323i at the shop. This included all new dampers and springs, front control arms, tie-rod ends, and most importantly a complete set of bushings at all suspension points. It’s this last part that is tricky for shade tree mechanics.
After two weeks of 20 hour days and late nights, Bill Caswell and I were sitting at the local watering hole around the corner from VRPerformance wrapping our heads around what we got ourselves into. Despite all the late work, we were not 100% done with the car.
But, before we could even get to Newfoundland for the race, there were two thousand miles of Canadian highway and one very long ferry to tackle. There was still plenty ahead of us before we started the race. So we drank beer until the bar closed.
It's been far too long since we last spoke. Much has been going on at the shop the last few months, so the time to post simply wasn't there. To kick things off for 2013, we thought we'd take a quick step back and bring everyone up to speed on "Target Targa", our 2012 Targa Newfoundland adventure. And because everyone loves a good video, we'll have a few of those in the next several entries...
One of the most balanced, best handling cars on the market today is the mid-engined Porsche Cayman. But, like every car coming out of a factory, it can be improved. Thanks to worldwide noise regulations, the stock exhaust stifles the glorious flat six cylinder engine note just a bit too much. Enter Fabspeed.

I think I may have fallen off the GT wagon with the latest modification to my E46 M3. The last time we spoke, I installed a TC Kline Racing suspension. Next up, the exhaust.
Aerodynamics on a street car is important for efficiency-- how easily it can punch a hole through the atmosphere. On a race car, aero is even more important for handling. A splitter-- typically a horizontal plane extending out from below the front bumper, helps push the front end of the car down and consequently aids front end grip or traction. Balanced with a wing at the back, a splitter is an integral part in the car's handling.
Because the splitter is usually very low, it is vulnerable to trailer ramps, track burms and digging into wet grass should you have an "off". If it's attached to the front fascia and you have an off and bad things happen, you can kiss the front end of the car good-bye. The solution is to attach the splitter to something more robust, while allowing it to break away should an unfortunate incident occur.
Having worked on hundreds of cars over the past 5 years or so a few things have become abundantly clear: no two jobs are ever the same, even if the parts being installed are, instructions from the component manufacturer-- if they exist at all-- are almost never complete, and finally, exhausts never ever fit without a good amount of "tweaking". A quick example of tweaking is presented after the jump...
We've got a new project at the shop; a 2006 Mitsubishi Lancer Evolution IX, or EVO for short. While we're well known as a premier performance shop for European sports cars, in actuality we work on all cars that have a sporting pedigree. And the EVO certainly has that in spades...
To wrap up the E92 M3 project-- for now-- we have a few smaller items to report on, specifically brake lines and pads.
Regular readers of this blog know we're all about balance at VRPerformance; and if you've been following the E92 M3 project build you might have asked why all the power upgrades alone? Well, you are premature with that jaundiced eye, since suspension upgrades were part of the plan since day one.
Advances in electrical engineering have allowed the venerable internal combustion engine to stay relevant in an increasingly hostile environment. A myriad of computer controls actuate precision crafted mechanical components in order to increase the efficiency and cleanliness of modern engines and the S65 is no exception. Since we’ve replaced some major engine components on our customer's E92 M3 in search of power, we needed to let the brain that controls it all "in" on our secret...
There are many ways to increase the power output of your engine to make you car go faster. Conversely, there are also ways to use less power to make you car go faster. It's all about how the power is utilized. The engine not only drives the wheels, but it also powers accessories that do nothing to motivate the car (they run the AC, power the lights, and pump fluids to the steering rack). This is often called parasitic loss. Reduce the drag and use less power to drive the accessories; you have more power left over to motivate the car. Enter the “underdrive” pulley...

Obsession. Obsession alone can be a bad thing when life and limb become irrelevant to the end goal. Obsession to craftsmanship on the other hand can be very good indeed. Quality is an ideal we obsess over at VRPerformance, and when we find a product that exemplifies this ideal we can hardly contain ourselves. Enter the Akrapovic exhaust system for the E92 M3 project...
Just as the E46 before it, the E9x series M cars are phenomenal straight from the factory. With a 414 hp V8 under the bulging hood and a sharply tuned suspension keeping things in check, it's hard to beat this sport sedan with even the most dedicated sports car. So what's an enthusiast to do when it comes to sharpening the scalpel the local BMW store delivered him? Turns out, quite a bit...
The third installment of our Japanese make-over mini series stars a 2008 STi. All new coils for the struts, sway bars front and rear, complete new exhaust including down pipe, and new trans and engine mounts.

Part 1 of EVO, EVO, STi went through a brake rebuild on an EVO 8. In this installment we go over a sway bar installation on an all new EVO X.
Spring is in the air and the sun is rising on our Japanese performance car customers. The last few weeks we've had a rally of AWD sports sedans come through the shop: a couple of EVOs and a new STi. In part one we describe rebuilding brakes on an EVO 8. Part two goes through a sway bar install on a new EVO X. And part three follows a complete suspension and exhaust upgrade on a new 08 Subaru STi.
We already talked about issues with the E46 series BMW rear sub-frames in an earlier post, here is some follow-up information. The amount of damage on the vehicle in question was so bad that we decided to have the OEM sheet metal replaced completely instead repairing it by welding. Thankfully BMW stood behind their product and actually warrantied the repair portion of the work.

We've written about E46 M3 projects before, but most of those projects were hard core track oriented. What we have here instead is a perfect street set-up for the M3: more power, more sound and better handling. Our time honored philosophy of balanced performance was followed to produce a car that is better in every regard than stock without any one aspect overshadowing another.
There is no doubt that the BMW E46 3 Series line up of cars is great. They are right sized, relatively efficient to operate and have superb all around performance. But there are critical weaknesses in the chassis-- especially in the M3 version-- that need to be addressed. We already reported on the fatigue issues with the front strut tower in an earlier blog entry. This time we will focus on the rear subframe.

A few weeks back we announced that VRPerformance is going racing in SPEED World Challenge Touring Car. It is a daunting exercise that we are nonetheless excited to start. The first step was picking the car.
We have installed plenty of Super Sprint exhaust components on cars over the years. They make a superbly engineered product with plenty of research and development to back up their performance claims (and price). The biggest down side to Super Sprint is the sometimes sketchy build quality and comparatively high price. There are some good alternatives out there, including the Agency Power units we installed on an E46 M3 recently.
Squeezing more power out of a turbocharged 2.5 liter flat four cylinder engine is as easy as swapping out the original turbo for a bigger one, right? If only it was that simple.
A few weeks back I posted the first entry in my "M3 GT conversion" series. I mentioned that the next step in my quest to turn my 2003 E46 M3 into a true "Gran Tourismo" is installing new wheels. Well, they are here!
This is a note for all of you who run heavier springs on your E36/E46 BMW. We have had a rash of M3s come into the shop with cracked FRONT strut towers lately.
We began this project car with a clear focus on improving the performance of the suspension and the brakes, since the engine already had a thorough going over by another shop a few years back. The one speed area of the performance equation we decided to improve right from the start was changing the gear set in the differential. The biggest bang for the buck is not in adding power to the E30 engine, but changing how the exisiting power gets to the ground. This is espcially important at the track, where this car will consume most of its gas.
The BMW 1 Series has only been showing up on people's driveways in the States for a few months now and already there are enthusiasts ready and willing to fine tune it. A great performance car straight out of the box, it none-the-less comes with the compromises every modern car has. We've talked about this often enough: in order to satisfy the government's regulators, insurance lobbies, and the average consumer, new cars are "sanitized for our protection."
We're glad to report that the E36 M3 race car passed its first technical inspection and the owner/driver has his first couple of races under his harness belts. The basics we completed before the first race-- installation of safety components, removal of non-essential weight, thorough maintenance and re-build-- worked as planned. Now it's time to further develop the car, and the first area we touched was the suspension.
In the final installment (for now) of the Civic Si project we tackle the suspension. The suspension really is the most important aspect in the overall performance of the vehicle. All the power in the world doesn't help if you can't control it. You want the four tire's contact patches touching the ground in as balanced a fashion as possible, controlling the car's motion. A good suspension set-up works with the tires and the road to provide the best possible grip in all conditions when accelerating, cornering and braking. Its mission is to keep the wheels planted and the body stable. We specified the best TEIN kit available, the "Driving Spec Control Master Type Flex" coil over system with "Electronic Damping Force Controller" (EDFC).
Lawyers want to argue in front of the Supreme Court, soap stars want to appear in a summer blockbuster and race car drivers want to win for Ferrari—every discipline has its ne plus ultra that those toiling in the trenches aspire to. For an automotive performance shop it is building race cars. Which makes sense, since a race car is the ultimate expression of the performance automobile and a real test (and testament) for its builder. You’re putting your ideas, engineering and craftsmanship up against others in an open competitive arena. What works and what doesn’t is immediately showcased for all to see. Here’s our first attempt at building a race car for the NASA GTS series.
The "Ultimate Driving Machine" tagline is over 30 years old now, and it's safe to say that even non-enthusiasts know exactly what carmaker belongs to that particular phrase. BMW's brand marketing consistency is equaled only by its product consistency. Okay, so that's just a bunch of fancy mumbo jumbo to introduce this latest ad, which we think is pretty cool. Watch it after the jump.
And the transformation of the Civic continues... One of the weak spots on the 2006+ Civic Si is the braking system-- perfectly adequate for street driving but toast on the track. Our balanced approach to all things automotive dictates that we look at the entire system as we make upgrades. We've already tweaked the suspension some, detailed here (and there's much more to come in this department, stay tuned) and upgraded the intake and exhaust system, detailed here. So now it's on to the brakes.
The drive shaft on the modern GTO is a known weak link, and when any modifications are made to the power output, it is a good idea to upgrade it. The last time we checked in with this particular GTO, you'll remember we released some extra power from the 6 liter V8 by opening up the exhaust system. The suspension was already tweaked with some better bushings all around, so we tackled the driveline here.
The last time we saw this particular Mitsubishi EVO was back in September when we installed new sway bars and upgraded the suspension bushings, Truly EVO Sway Bar Install. This time around we're replacing the stock struts with Ohlins units and upgrading the braking system with a custom brake cooling duct kit, stainless steel braided lines and new rotors at all around.
The second phase of our E30 M3 winter project is to tackle the suspension (see E30 M3 Rebuild: Brakes for phase one). We began by first inspecting the suspension on the ground as well as checking to see how the car behaved dynamically on the road. We decided, along with the car's owner, to go ahead and replace the dampers at all four corners, upgrade the sway bar size to help flatten the cornering characteristics as well ad eliminate some of the understeer, and replace some of the worn out suspension bushings. We tried to replace every stock part with a more performance oriented equivalent since the car will primarily be a track tool and not a boulevard cruiser. That means the around town ride quality may suffer a little, but with the payback coming on the track.
A BMW E30 M3 has taken up residence in our shop this winter—in out of the cold Midwest winter for a deliberate going over. The car has been tracked extensively and things have begun to wear out. We have been tasked to do a thorough technical inspection, replace, rebuild or repair what’s bad and give recommendations where the aftermarket has made improvements over the original equipment hardware. In other words, make it just I bit better than new.
Watch any British car show and you'll see plenty of powerslides-- artful footage of an exotic car speeding tail out around a dank English test track. Unless you’re on a dusty rally stage, sliding around a corner is not the best way to get a good time. But who cares, it looks cool. Follow the jump and learn from 5th Gear's Tiff Needell how to do it right.
As you know we at VRPerformance always preach balanced performance. High horsepower or sticky tires by themselves do not make a great car. It's how all the bits work in concert that separates the merely fast cars from the really great performance cars. And when you think about upgrading your car, it's important that you think about balanced performance-- incremental change to the system instead of lopsided focus on one component or another. Do it right, and you can fetch a new Nürburgring record (video after jump).
In 1964 Pontiac engineers stuffed a 389 cid engine in a Tempest, called it the GTO option, and created arguably the first mid-sized muscle car. Almost fifty years later, GM tapped their Holden enterprise in Australia-- where muscle cars still thrive-- and created the modern GTO. Equipped with GM's venerable small block V8 engine, the current GTO is based on the Holden Monaro. A disappointment to many GTO loyalists, thanks mostly to its bland styling, the modern GTO is nonetheless a good enough performer. But good enough is the enemy of better at VRPerformance, where we feel that almost every car can be improved with the right equipment and service.
A typical stabilizer (a.k.a. sway bar and/or anti-roll bar) swap takes a half an hour to maybe one hour if the end links are in a bad spot or the bar needs to be fed thru a tight area. The front bar on a Mitsubishi EVO is a whole other problem, requiring a great deal of disassembly just to see the bar in the first place, let alone take it out.
We're constantly preaching balance to our customers when it comes to installing performing upgrades on their cars. It is our philosophy that a car has three basic objective measures and one subject measure when it comes to performance: positive acceleration, negative acceleration (also known as deceleration or braking), and lateral acceleration (turning, or the ability to change directions). The fourth measure combines the three objective yardsticks into a subjective rating that's all about balance and feel-- how the three acceleration measures combine into a whole experience.
We work closely with our customers to put together a performance package for their car that best fits their needs. The new Civic Si is a great car out of the box, but it's not perfect. And when you take it to the track, as the customer in this case study does, the weaknesses are amplified. The Si has plenty of motor, but is lacking in the braking and grip departments.
The Michigan Volkswagen Enthusiasts club along with their counterparts at Motor City Audi came together again and organized the 4th annual Motorstadt. Held in the shadow of the Volkswagen group hedaquarters in Auburn Hills, Michigan it is an event for VW enthusiasts of all stripes. The cars on display included totally original classic air cooled VWs to ultra modern and highly tuned VWs and Audis.
There is no real trick to mounting wheels and tires onto a car, but when the results are this cool we just had to share.
The installation of Supersprint headers on an E60 M5 was one of the more physically challenging projects to come through the shop in a long time.
If you’ve ever looked under the hood of a modern M5, you've probably noticed that the engine compartment is filled with V10 engine with nary a gap between it and anything else. As beautiful and organized as it is, it is not a friendly place for aftermarket go-fast parts. Looking over the detailed 10 page instruction booklet that came with the headers we were a bit worried that this project was going to be massively time consuming (and costly) for the customer.
