Joe Touch Posted August 19, 2011 Share Posted August 19, 2011 So, I have done some power and brake mods (http://www.socalsubies.com/forums/showthread.php?t=7935). Now, it's time to get some suspension mods. I don't dd it, she's mainly a garage queen and my goal is to track it, so I figure this is a good place to start. This is what I am planning to do: AST 4100 12k/12k vorschlag camber plates w/ custom machined ast perches whiteline anti lift kit/caster kit whiteline Rear Control Arm Kit whiteline roll center adjustment kit/bump steer kit whiteline front inner control arm bushing kit (might as well while i have the arm off) I am also considering the perrin P.S.R.S rather than the whiteline version. Don't know if I want all that NVH. From what I can tell, the rest should be a very solid set up for the track. Any input/experience with/for these parts would be appreciated. Thanks for reading.

socalsleeper Posted August 19, 2011 Share Posted August 19, 2011 I have not had much experience with caster changes on a track car, BUT I have not seen a car with 100% equal caster on both sides. I believe the perrin set up is a bit more adjustable. You might need caster on only one side so adding .5 of caster to both is not always the best solution. What you want is adjustably over fixed settings, and serviceability ie bushings with zirk fittings, more control over front and rear camber and toe. If you are a set it and forget it kind of guy, dosent mean you should not have adjustable parts. This will just mean that once you get your car dialed in how you like it you can leave it alone. Hope this helps, my build with have lots of adjustability, which means I can keep my tires in good shape longer, and do good on the track when the time comes.

Joe Touch Posted August 20, 2011 Author Share Posted August 20, 2011 Thank you for your input. I have decided to go with the perrin. My goal is to build a track car, not a fast DD. The biggest thing that I was worried about was the increased NVH, but again with my goals, the perrin makes sense. Joe Link to comment Share on other sites More sharing options...
socalsleeper Posted August 21, 2011 Share Posted August 21, 2011 Sorry but I haven't heard the term NVH. I have more than my fair share of acronyms to keep track of at work... Please explain. Link to comment Share on other sites More sharing options...

socalsleeper Posted August 21, 2011 Share Posted August 21, 2011 I can tell you right now if you replace all your bushings with harder ones, and add some coilovers and track the car you will shake a kidney stone loose. A dedicated track car is not comfy. Many times tracks will require roll cages after certain power levels, or lap times. That means no interior...
