My car is an AP1 with 1 inch drop and hardrace offset balljoints in front. I did not install the roll center adjustment plates.

My alignment is:
Front camber 3 deg
caster 5.9 deg
toe 0

Rear camber 2.8
toe 0.26 deg total

The problem is my caster is maxed out and the guy (very very experienced with track s2000's) could not get anymore out of it. Any ideas on what can be wrong?

 

nothings wrong, people don't get 7 degrees of castor with -3 degrees of camber. your setup is fine but if you want more castor you need to remove some camber

 

good to know.

Thanks

 

With J's S2 joints (more aggressive joints) people are able to get more caster along with aggressive camber.

 

You can get more if you lower the car but I use 6-6.2 just fine. I am actually against using much more caster than that (some people use a ridiculous amount like 7+ for high speed stability)

 

I'm with him. 6.0 works very well for me.

 

The primary reason people run high caster is for dynamic negative camber gain in low speed corners, not high speed stability. No one has ever claimed their S2000's 'high speed instability' was cured by extra caster.

 

very very correct!!
