Have you got longer bolts for the 5mm spacers? As IIRC you dont need to, may have something to do with the stress on the bolts but thats just a wild stab in the dark, maybe just invest in some 5mm then, how much did you get them for if you dont mind me asking
just used the standard bolts that came with the adapters. i have an impact wrench so made them super tight. i am going to check them again in a few days to make double sure!
wat u going to do nxt?
