i've been trying to figure out options for my 2nd set of wheels and tires.stock wheels 8.5 x 19 and 12 x 19 rims,with mpsc 235/35/19 and 305/30/19's. car has just been lowered 6/10''. car was just corner balanced and camber was set to 2.6.front and 2.2 rear.this is the set up i'm planning now,and i want to comfirm that this will work with no problems.i'm curently planing on about 25 track days this year. the oem set i will also use for track days, as well as 1-2k miles on the street.-----------------------so here my planed set-up.champion RG5 9 x19 and 12 x19 (painted in black).with hoosier R6 size's 235/35/19 and 325/30/19. is this the best set-up? i was also told to have someone check the rolling diamenter.will i have any issues with going this route.
thanks stuart

 

I'm going through similar decisions for this season in terms of tire size. I think that the 325 in the rear may give you too much push. I like your choice of camber set-up. Thinking about going with 18 inch wheels this season for more choices. See you at the track.

 

yea i'm on the fence about what size also.now as of yesterday i changed things again.i'm going to do the ccw c10's with 18'' wheels.mpsc the 235/4ozr18 91y are in stock at the rack but rears are on backorder size 315 and 345/30zr18's .bf goodridge the fronts will be releaced 2/29 in 245/40zr18 but no releace date for the rears in 335/30zr18 yet maybe tommower we will get a update i hope.the other option is toyo245/40zr18 93y and 335/30zr18 102y or 235/40zr18 91y and 315/30zr18 98y.i'm checking what is aviable tommower.which toyo setup would be the correct sizeing.very confuesing
i also had someone telling me about the push thing with different setups,and i am not clear about the physics. have you pinpointed correct tire sizes for this car.
ps i love the color of your car
