I just noticed that the locking wheel bolts that came with my car are shorter than the real bolts and also have a different shoulder depth... Can someone tell me where I can get correct locking wheel bolts please?

For what wheels and are you running spacers?

Standard wheels mate... Well, the rest of the bolts are standard. Ideally I'd like to buy new bolts all round. On the back I'm going to have 5mm spacers so ideally 5mm longer bolts on the back. Any advice?

Dont your new wheels require taper bolts now rather than standard raduis bolts?
