i just purchased a set of 19x8 rs4 wheels. they are 45 offset. they are hitting the front calipers. please give advice on what size spacers would be best to use. and also do i need to space the front alone or front and rear??? thanx for help

 

5mm would be plenty and i would not do just the front. do both.

 

ok. do i need to get new wheel bolts??? extended ones

 

you will need longer bolts so if you are planing on getting 5mm spacer make sure the bolt is 5mm longer than the factory ones
