Suspension recommendations
Blew the front JOC/Pfadt shocks yesterday and am looking for ideas to replace these and/or step up to coilovers. So:
Car is a 2010 GS, driven about 80% track, 20% street. Usually run MPSS tires but in interest of better lap times, I switched to R888s. Not likely I will go back MPSS or similar tires. Goals are:
- what would be a good replacement shock?
- do the shocks need to match the sways?
- if going to coilovers, what is recommended without braking the bank?

- better lap times via improved handling (less dive, squat under brake, throttle, flatter thru corners, etc.)
- better feedback from the chassis / steering if possible
- reasonable price (no Moton or Penske)

Bolt on a set of LG GT2 coil overs and be done with it. Night and day better than the "P" brand you had on there. You're better off running their sways, but you can always change them later. I found that my Pfadt sways weren't doing much due to the splines on the ends of the bar allowing so much rotation before actually engaging the links.

The ideal setup is LG G2 (not GT2) coilovers, LG Monoball suspension, and T1 bars with adjustable end links. GT2 is Chinese adjustable stuff, skip it. G2 is Bilstein non-adjustable. Let Anthony spec the springs and damping and you will find a great setup. Yes it is non-adjustable but trust me it is faster than 97% of the folks on track and they are trying to fiddle with *****. After 2 years of racing my G2's went on a shock dyno proactively to confirm they were not in need of a rebuild. Bottom line: there were perfect: shock guy said they were so consistent side to side that he finds many new higher priced shocks did not show the same repeatability when new! In addition, I tried stiffer spring rates then Anthony recommended and went > 2 seconds slower (jumped 200lbs front and 100lbs rear). I THOUGHT I had too much dive/squat but as it turned out that was necessary mechanical grip and going stiffer made the car a lot slower.

^agree with the above posts. I just switched over to everything LG (coming from Pfadts)....lets just say I finally know how a car should really handle when driven like a track car. Went with G2 coils and G1 sways.

Is a change to coilovers a waste without a change to poly or delrin bushings as well?

I ran mine for a short time with just the G2 coilovers and stock bushings, it was noticeably better. When I went with the MonoBall bushings a short time later I could drive the car with my fingertips at the edge of traction the whole way around the track, sliding the front or rear at will (no aero).
