245's all around for AX?

i would run staggered tires on a race track (i run 225/265). the sways are great for either, as is a performance alignment. not all shops understand what's required in a performance alignment, but if you give them the settings, any shop should be able to dial it in just fine.

So how about some settings both front & rear that would help me out at track days and not hurt me on the street. 02 S, factory wheels, summer tires.

sure; start with this:

front toe: 0.0
rear toe: 1/16" per side
front camber: -0.8deg
rear camber: -1.1 deg

that should be a nice start. if the tracks you run are tight and don't have many fast (>80 - 90mph) turns, you can go with zero toe in back.

I like insite's alignment suggestions. Very close to what I run for street and autocross use. The zero rear toe may be a bit much for some people, because it biases the car towards oversteer a bit. For more stability on throttle, run 1/8" total as he says.

I have insite's adjustable front sway bar links and I love them. They're the beefiest, best built links I've ever used and they haven't made a lick of noise in 500 miles of street driving.

I pulled the trigger and went with the 245/275 setup on my 17" x 8.5" stock wheels. Does anyone know if I will need wheel spacers? I run a 2002 S with stock suspension.

Just did my first test and tune with the 996 GT3 front sway bar and 245/285 Kumho V710s on stock wheels. -.7 degrees front camber, -1.2 degrees rear, zero toe front and rear. Bar was set to full soft. On cold front tires, lots of understeer. But once the tires warmed up, the car was very well balanced. No understeer to report except in very tight turns. Slaloms are brainless now. Floor it and steer. No more inside wheelspin in slaloms. Nice lift-throttle oversteer characteristics, and neutral handling on-power.

31psi front and 33.5psi rear on 40-run-old V710s with a bunch of heat cycles on them. If it stays dry this weekend for our first local event I'll get some good data on how the car is relative to some of the best drivers in the country.
