I've got 10mm spacers on the rear with 40mm thread length bolts. I put these on the rear short term until i got some 15mm spacers then i'll be putting the 10's on the front and 15's on the back. Due to this being short term i'm currently driving around with no locking bolts on the back (silly i know). So my question is... If i bought a set of 4 45mm McGard locking bolts, is this going to cause me problems on the front wheels? I.e. is that extra 5mm bolt length going to interfere with anything? Maybe a naive question but i could do with knowing! Cheers. Paul.
