Help - I have 15" BBS alloys on an H reg Mark 2 GTi and I've just had them re-furbed - I wanted to put locking wheel nuts/bolts on (now they're worth more than the car!!)- ordered genuine VW bolts only to fine they are too short. I've been told that there were 'special edition' BBS alloys put on some GTis - is this true? Where would I get the right bolts from??
