Open Track Day April 2011

The VRPerformance Open Track Day at Grattan Raceway Invitational has become an annual must attend event for many friends of the shop. With its minimum number of rules and absolute maximum amount of track time its a great way to spend a day learning about all the upgrades we performed to the cars (or need to). Check out the gallery after the jump.

We didn't have a lot of time to take pictures; nonetheless, here are a few of our favorites.

Thrust Sheets to the Wind

One of our good customers complained of "pinging" noises coming from his front suspension-- a TC Kline Racing double adjustable coil-over set-up we installed last fall. The pinging noise is due to the springs binding as they compress. Our first, quick, remedy was to grease up the coil perches so that the springs could freely twist during compression.

This only worked for a short while so we had to look for a better long term solution-- a bearing surface that would allow the coils to twist freely. Enter the thrust ring, or "sheet"-- basically two large washers, one made of a Delrin type material, the other hardened steel. These are placed between the coil and the perch.

We will be recommending this solution right from the start for those who drive their cars predominantly on the street and like a quiet ride. Putting them on after the fact requires dismantling the front suspension completely-- not a quick job.

While we were at it, we cleaned up the perch threads and re-applied some T9 lubricant (a good maintenance procedure to do every season).
