I have just spent an hour searching this and can't find it on these forums or the web...what is the diameter of the VS road wheel center bore?
AFIK Commodore Centre hubs are 69.5mm pre VE and 66.9mm VE.
Doesn't answer your question but hope it helps.
Thanks for that, problem solved
VS center bore size is 120mm
DBA rotor catalogue shows the VS centre hole as being 70mm and VT-VY as being 71.5mm. Not sure if this is the same as the wheel centre bore size.
A center bore hole is the hole on the inside of the wheel which is 120mm for the VS
Double post sorry.
The center bore isnt the actual size of the bloody hole I know that,what Im saying is that halfway from one stud to halfway to the furthest stud is how you measurer the center bore which is 120mm for a 5 stud pattern.This part of the wheel is called the center bore.

I didn't mean to start WW1V but the center bore I was referring to is the hole that sits over, (or locates on) the bearing hub. Bear gave the size as 69.5 for the VT and I believe the VS is the same except for the part the brake disc locates on which is larger. Pax. Maybe should have simplified it by saying "the hole in the center of the wheel"?
Thats ok mate we dont mind a bit of arguing on here,the way they determin the center bore is they use pythagores rule which is measured halfway from the furthest stud holes, and the hole in the wheel would then be about half of that size.I know its all technical jargon but your right its easy as just measuring the hole in the wheel,but the size of the hubs and studs are not the same in every car thats why you need to measure it to make sure your wheels can fit onto it cheers.
If you draw the five studs like on a wheel and then draw a circle starting in the center of the stud and then threw all the five studs so you end up with a circle which is called the PITCH CIRCLE DIAMETOR,thats known as the center bore.
THE PCD is NOT the same as the centre bore. They are 2 separate measurements hence why the centre bore (CB) and pitch circle diameter (PCD) are listed separately.
