Picked up a set of BFG R1s. From tirerack in 235-40 17s. Should provide enough grip and be a 1/2″ shorter than the old 225-40 18s kumhos on for the street. Traded for a car years ago with BBS CH 17s to match my 18s one of my favorite wheels. Have to run those. Now with all the grip better turn down the power a bit or somethings bound to give up.
