can i use spacers on just my rear wheels, or will that mess up my performance and handling? i want to fill the rear wheel well a lil more, but i cant push the front wheels out much more becasue of rubbing issues. will it be possible to put them on just the rear wheels?

 

how much more do u want to push them out
u cant go too far or it gets really bad

 

i was thinking 8-15mm. would that be too far? what would get bad?
