Hey. So I have a 2017 Lexus IS200T F Sport and I'm about to change up my stock wheels to the ESR CS15s. I need help figuring out what tire sizes I can run without too much of a stretch and if anyone knows what size spacers I could get for it to clear in the front since I have the bigger brakes. I'm lowered on BC Coilovers and have camber arms coming in as well. I'm also wondering how much camber I would have to run on this setup. Basically going for a slight stanced look while maximizing tire life.

Front :
18x8.5 & 225/40/ZR18

Rear :
18x9.5 & 255/35/ZR18

Switching to a square setup and the new wheel specs are 19x9.5 +22 Offset

 

you could probably go up to 245/35, but you may get rubbing issues in the front. 235/35 or 40 should be okay. with all the mods you're doing, you may have to do your own R&D; although it will be pricey
