18"x10" and 18"x10.5" Track Wheels Options?

when you run a tire too wide for the rim width, not only is that grip response slowed, but their is also more contact patch deformation while cornering.



285/35/18 on 18x10.5 all around is the ticket. Martin and i will be running RS3s in those same sizes soon. im also getting NT03s as my track wheels soon also

in the front et30 is the safe limit inward, and what i run et28 is in my opinion the safe limit outward with a 285/35/18 tire and -3 camber. no rubbing on anything what so ever, you might be able to run more aggresive offset, but i havent tested that so i cant say for sure. Just i know under track conditions, those offsets are proven in front
