Does anybody know how big of a slick you can stuff under a stock wheel well on an 89 formula?

 

Without any modifications, I know a 28x9 will fit with no problems. I stuffed a 29.5 x 10.5 under my fenders with some inner fender modifications.

My car is back halved now with 32 x 14

 

is that stock wheel well with no other work, or what will fit with further ...adjusting? you can fit a 28-10.5 w under it but you will need to remove the bump stop brackets and do a little massageing, I think that a 325/50 15 drag radial will fit with the same mods, but less chance of rubbing at speed since they do not grow like slicks do

 

i'm running a 29x9 hoosier on a 15x8 wheel with 4.5" backspacing.





only fender modifications is some BFH massaging and rolled fender lip

 

my tire measures out to 28.5x11.50 DOT slick or 28.5x10 slick..

all on a 15x8 with 4.5" bs.. only mods were barely any BFH clearancing..
