Should i change out my 17x9 04' cobra wheels for 17x8 01' cobra wheels? Which ones would be better for auto-x/ RR ? I run a 255 on front and 275 on rear and the 255 look maybe too small and any bigger and it'll rub like crazy. Any input? What are some lighter weight 17x8's that are 5 spoke, if i need to change up?
