I ran a 2002 C2 for 2 years in the stock class, I had -1 camber up front and 0 toe. at the back I had -1.5 camber and everything else stock.. that setup worked very well for me.. I laso rand the Sumis III and found that they didnt like high temps, for autox I had 40psi at the fronts and 45 at the backs.. Hope it helps..

wpw thanks... it was hot when I ran them and the morning they were much better... 40/45 !!! WOW I think I would have a drift mobile with them that high!!

I will try higher...I can always let air out... hard to put it back in

Thanks for the replies, I will check the numbers,


the toe is in (mm) not degrees - I will ask for a conversion, this is helpful!!

How many miles have you put on the new Sumis? Just read in the Tire Rack that it takes about 500 miles to wear off the lubricant used to release the tire from the mold.

~ 100 then (200 now)
I did want to have them on the ground longer before taking them out, but the alignment shop was booked up and the car sat for 5 days

well maybe they will come around....

0.28 degrees front toe and 0.30 degrees rear


converted mm to angle for toe settings

Nice pictures. Thanks for the write up, especially since I'm getting the Sumi HTR ZIII's put on tomorrow and will be out at Pocono on Friday of next week.

Gotcha - so a bit more than stock.

If I'm doing my angle-minute calculations right, stock front is 0.08 degrees and stock rear is 0.17 degrees.

nice Ed, glad you are happy with the setup, nice stance as well... how about putting a chin spoiler up front... cheap mod. Are you still using stock ARBs.

'Zero' the front toe and you'll like the handling a bit better for AX.
