i just got some m45 rims and the fronts don't fit without a spacer, the question is will 5mm spacer clear the tires from the control arm? i've read that sometimes it does and sometimes it doesn't. also, at what point will i need longer studs? would i need longer studs for 5mm or 5/16 inch spacers?

 

From my understanding you don't need longer studs just yet. Anything bigger than 5mm will probably require extended studs. Someone please correct me if I'm wrong.

 

I would get 15mm all around. Trust me it will look better.

 

i have 10mm spacers all around w/extended lugs, came w/the wheels... if i hadda buy 'em, i woulda went 15mm.
