For me the search for the best track tire for my 360 CH is over Hoosier R3S04 245/35ZR-18 Front (wheels 8x18) 305/30ZR-18 Rear (wheels 10.5x18) What a tire! took me two pit stops to get the right temperature distribution and pressure - it makes the car behave perfectly on Pacific Raceways by by everybody and they look good too Now I am wondering what the Stradale would do if one could put the tires on ditch the carbon brakes; use 18 wheels; adjust suspension . Note that for a 360 Modena one would have to roll the fenders according for Challenge specs. I bought the tires from Bob Woodman.
I have tracked my 360 coupe enough that I think I am approaching the top of the learing curve on street tires. I am thinking about track tires (and, at the minimum, different brake fluid and perhaps different pads)--any suggestions on who to roll the fenders, and are there any issues with paint cracking/warranty etc. that you can think of?
If you are just wanting good track tires (rather than street tires), there is no need to roll the fenders or get new wheels. If you do want to get new wider 18" wheels, then if you get the right offset, you still won't need to roll the fenders. I've heard you can even fit 13" wide wheels with Hoosiers on the back... given the right offset.
I don't think the rear is the problem Not sure what you mean by 13 wheels this would mean 335/30 Hoosiers in my books and a.) I dont think a 12 tread fits (for sure not on the Modena) b.) I also dont think that the traction balance is off to the rear with the 360 The 245/35 and 305/30 combination keeps all dimension as close to the spec. from a performance standpoint as I could find - and having run the tires I am super pleased; this is as close to racing slicks as it can get with DOT tires Fyi the GTC uses 10x18 265/645 and 11x18 305/680 which I believe is the way to go however I could not get the rims and the Pirelli tire prices freaking me out by rolling the fenders I meant what F calls "front mud-guard edge folding" - i.e. folding the lip that reaches inwards upwards
