I am on the fence about my settings. My car is being built for HPDE and autocross but most HPDE. In addition, I DD the car right now. Currently my setup is as follows:
2003 AP1
cusco front sway bar and lower tie bar, ap2 rear bar
225/45/17 front and 255/40/17 rear tires
-1.5 camber front, max front caster, -2 camber rear
0 toe front, 1/4" toe-in rear
KW clubsport coilovers

I'm thinking of either moving to 245 front and 255 rear tire setup or sticking with 225/255. What are your thoughts on this?

I'm going to add more negative camber all around soon, but I'm torn on the toe settings, should I add bit of toe-out up front? Also for the rear, should I dial back the toe-in to something like 1/8" or 3/16"?

 

Looks OK to me for now. I'd adjust after to see how it feels and tire wear is. I'd probably add a little more neg. Camber in rear and dial back rear toe a hair.

 

What is your suggestion for the rear? Move to 1/8" or 3/16"? For the front should I leave it at 0 toe, or go for a little toe-out like 1/16"?

 

Front toe 0 and rear at 3/16 total toe. Though where rear toe is now should be OK just no more.

 

Are you still on stock ball joints in the front?

 

Yes, but I will get offset bushings soon to allow more neg camber up front. But for now, I'm just wondering with my club sports, ap1 and staggered setup with the big front Cusco sway bar what others would run in terms of toe settings front and rear.
