There is a slight difference to the stud pattern

HQ is 120.65mm
Commodore is 120mm

Commodore studs are 12mm
HQ are 7/16"

Centre hole size is different on the wheels

Offsets are vastly different so you might find the wheels foul on the suspension and or bodywork as the wheels are essentially a FWD offset pulling everything in away from the guard

Incorrect wheel fitment can lead to breaking studs and losing a wheel
Not to mention the associated insurance problems

offset will be wrong ... I am running the wheel adaptors on mine and have had no problems so far, by memory I got them from St George tyres on ebay, they fix the offset by 30mm as well.

Cheers for the quick replies

and those stud pattern measurments are handy to know so thanks

i sat one of then rims under the car on the rear and it wasnt going to hit anything but if i used those adaptor plates and they added an extra 30mm they will hit the guards for sure.

According to an article in Street Machine wheel adaptors are not legal in any state unless fitted by the vehicle manufacturer. They are definitely not legal in WA or any state that adopts the NCOP.

It may be possible to make an adaptor that is safe however it still will not be legal. If you survive an accident as a result of using the hub adaptors you may wish you didn't. Your insurance company would have the option not pay out for damage to your vehicle or any damage you do to other vehicles or property.

Yes but they'd stick out a long way! :tease:

Most people change stud pattern in conjunction with an all-round brake upgrade. If you want to spend that sort of money then take a look at some of the options in various threads on this site and through the likes of Hoppers Stoppers.

Thanks mate

a brake upgrade isnt really on the list at the moment but will be done when the V8 comes into play. might just keep an eye out for some nice looking Torrie rims

Sounds like a plan, there is quite a bit involved in changing the stud pattern safely and costs add up quick

The stud pattern is the easy part. The big problem with Commodore rims is the offset. You can not legally use spacers to correct rim offset on an LX Torana. The rear can be fixed by fitting a diff that is wider than the standard Torana diff to suit the Commodore offset. Changing the front hub position to suit the Commodore offset is not as simple. Hopper Stoppers can make their front brake kit with the hubs set 8 mm further out than standard but this may not be enough.
