Commodore vs Kingswood PCD - the definitive answer

[Feenix]

Can you safely use Kingswood mag wheels on a commodore rotor, in a performance (ie: circuit racing) application.

Whats the definitive answer(s)?

* Is it unsafe?

* Why - its only <= 1mm??

* wouldn't manufacturing tolerances be about the same?

* Is there any evidence (personal experience) that has shwon this to be unsafe in a performance application?


Any help appreciated, particularly from DBA.

Many thanks,

Well... given that the 0.5mm difference means that you usually have to be fairly rough to get the wheel to slip over the studs and that the wheel then tends to be fairly tightly located by the studs instead of by the centre lug on the hub, I wouldn't be too happy about living with it on the road let alone on the track. I don't even know if the hub lug is the same size between Holden and Commode hubs. If it is different then using one wheel on the other is a no-no anyway. But given that I've seen Holden wheels on Commodes and Commode wheels on Holdens it must be the same I suppose.

i know when you use HQ rims on a commodore and vice versa that under hard brakeing you can snap the wheel studs off!!!!!!!

Can DBA confirm this is possible? My particular point is with mags, which are a bit different to normal steel rims in that the rims dont directly contact the stud, rather they contact a barrel type nut... lugg nut? not sure of the term.

Some people have commented its because of this there should be no issue. I tend to disagree, but I wanted some more factual or at least engineering based reasons.

Thanks for the input!

I think dbasteve is on holidays

HQ and Commodore don't really interchange...they are close but not the same.
In the interests of safety its best to fit what should be on the car....not what you think fits.
