RColt Tire Options - RComps - Racing Compounds

Trying to work out where do I start on the tire department, I want to go bigger.

Currently on the Z221, and they been going decent. Set a PB on them.
Running 215/45 and 225/45

Due to clearance issues, rolling diameter and width limitations, I have to be careful and always check these











Fitting the 215s on the fronts posed a few problems. I run a 20 spacer to push the track out. /rcolt-with-rays-57c-gram-lights-17x75.html
