just so you know the factory does not suspend the warantee for a 19 front and 20" rear set up. nor do they suspend warantee for airbox testpipes or exhaust. just so you know you can do it in the future without any worries. good luck as i guarantee you this is just the begining for you.

 

Wouldn't new wheels be ok as long as the over-all diameters of the new tires are same as stock?
