well i got a set of xxr 521's in 20x10.5 all around and i having problems with the rim hitting the front arch that holds the A arm.... anyone else having this problem???? how much clearance do you really need to have ??? i was thinking about getting a set of 10mm spacers but is that enough clearance???? im not going for hella flush just sorta flush lol

 

10mm front 15 mm rear

 

15mm spacer all around will give you that "sorta flush" look. You can even go all the way up to 25mm and fit with a roll or slight pull in the rear... depending on tire size.
