Extended Locking Wheel Bolts


Registered User
Good evening,
I've got +15mm bolts for the spacers on the front of my S3...I have a set of standard locking wheel bolts for my rears as they use normal bolts but any idea if I can get extended locking wheel bolts anywhere?....I got lost searching through ebay with different sizes...can anyone help with sizes of bolt or a link?...cheers, james.
