Marcus,
That looks a far better long term solution. I'd be looking for 10.9 high tensile studs at a minimum. Did you use threadlock on the studs where it bolts into the hub? And can you recall the overall lengths of the studs?
Cheers,
Graham
Graham,
Most studs are 10.9, there are some sellers that don't know or won't list the tensile, the one's to avoid, so go for a reputable seller if you want to go the same route.
I used the red thread locker by Loctite on the short part of the stud in the hub and controversial or not, copper grease on the part of the stud the nut would thread up to the wheel, nut tightened up with an impact gun and a torque wrench not had any problems with any loosening of studs or nuts over the last couple of years.
I bought an extra two nuts to use as the locking nuts for winding each stud in. I can't remember the length, but it will differ per car/wheel setup. The stud length will need to be the length of the original bolt (including head) plus depth of any spacers used. I have a wider front spacer than rear for example so different length studs to match. You can always buy a Chinese £1 jobby to check your happy with length of stud before forking out for a decent full set, I aimed at having the top of the nut flush with or just below the end of the stud when fully tight.
All the best, Marcus
