Getting ready for track season and I am thinking of making some changes to the car this year. I wanted to see if anyone else has already tried a couple of items I am looking at to check with fitment issues. I am looking at the Racetech 4100WT (wide & tall) for a seat. Wanted to see if anyone has installed one, biggest issue I can see is the shoulder width not fitting at the door. Second, I am thinking of running the new Apex forged wheels in 18x11 front, 18x12 rear. Couple of questions on this. Any issue running 18s on the front on track, rocks or rubber getting stuck between the rim and brake caliper, doing damage? Any modification needed on ZL1 1LE, plan to ask APEX but real world experience is good to have. Anyone running Toyo Proxies RR in 345/35/18 on the rears, will they fit? Thanks for any input.
