I was always told a minimum of three turns of the thread showing above the nut I knew a lad with a corsa gsi with a tuned calibra turbo engine fitted 220 bhp in a tiny front wheel drive car He fitted after market alloys and only had two turns of the thread showing after torquing up Being young and feeling invincible he thought it would do I had a machine shop press longer studs in after the front wheel came off as i just hit the apex of a roundabout at 50 mph
A friend of mine has a lathe so I'm going to have a word and see what he can do cheers guys , all I want is the nuts all the way down it will bug me unless they are
