We have had customers use 275/35/18 Hankook RS3s with the 18x10" ET25 EC-7's only rub on the fender liner at full lock or hard turning. The rubbing is very minimal and can be alleviated with added negative camber.
Sounds like a phenomenal car, we would love to see photos of it!
Ok thanks for the info. So would you recommend the 18 x 9.5 front with 265/35 RS3's for no rubbing?
