I am looking to upgrade to some STI wheels and 28″ tires. Unsure of what I want for tires, but looking at Rocktane XD’s. Do they run large? I’m not sure if I want the 27×9’s or 28×10’s all around yet either? My main question however is will I need or want a clutch kit when upgrading to these tires? Will I see a noticeable change in performance without one?
