It didn't on mine i had the R32 arb and weitech shocks with the oe LC wish bone and had no issues i only changed to the LCR wishbones and hubs because i kept splitting the cv boots due to the wishbone angle, the R32 arb sits above the wish bone so i cant see how they can touch?

hmm odd, i had my subframe down for fitting a new sterring rack, and i just held the R32 ARB in and see how its going to fit, and see that i touch the wishbone. but maybe it was because the arb was not fitted/tightened up on the subframe. you have done it so you are right, my mistake sorry.
 
Thinking of fitting a R32 front ARB and a Neuspeed rear. My question is is it better to buy a new R32 ARB or is a used one ok? Also how much difference do the spacers make?
