Need advise on setup for my G26 rear wheel drive.
Currently i'm on Rohana 20x8.5 offset 25(F) 20x10 offset 33(R), Continental sports contact 7, 245/35/20(F) 275/30/20(R) but my rear poke seems too much. Ordered lowering springs and is on the way but from the way my rear poke, I am worried it will definatelly rub my fenders.
SHould i change tyre brand as the rim protector of these conti seems very thick?
Should i change tyre size to 265/30/20?
