get intouch with castlemaine rod shop, these guys no all to do with any mod or conversion you can think of for a holden. they can supply a kit to fit HQ disks to a HR f/end, and a kit for the arse end as well(HQ has same stud pattern as c/dore).they are in vic but they provide engineer cert's which you will need for a RWC.'

further to your comments, v6 conversions in moree do this stuff http://www.v6convers... and i have the rack and pinion steering kit with adaptors to fit commodore brakes to the HD-HR drum brake stub axles and they work sweet, also i have been told that with the rohshop steering conversion you loose some of your turning circle and apparently with the v6 conversions one you don .

Also in regards to the above comments about the commodore wheels being the same stud pattern as a HQ, i thought that the commodore stud pattern was in metric and the hq is in imperial and if you use the wheels of a hq on a commodore (or vice versa) you will end up snapping the studs off and then then the wheel will fall off, and i can tell you from experience it can be nasty!

I am unsure about this so anyone feel free to correct me if im wrong.

Sammy.

The HQ and commodore stud pattern are the same, as the HQ was fitted with Chevrolet pattern to use the Pontiac GTO style of rims (we got 14" and not 15") and as it was decided to continue the run of the WB series into the mid 80s,and to keep cost's down, the c/dore used the same stud pattern as previous models. I have just swaped the SL/E rims back for my HQ GTS rims on my VC after having them re shod, and had no problems with alignment of the holes. you may be thinking of the tread size not pattern. '

In regards to the commodore rims, I remember a discussion similar to this on the fastlane site a few times over the last 3 years, and it revolved around that during the WB range (the commodores only changed) they changed from an imperial to metric, though some people have said they do fit. I would prefer to get rims that are designed for the stud pattern - eg. HQ for HQ stud, VP for VP stud, etc - as it can save any problems in the long term.

I agree with sammys comment as I have just gone through this, commondore and hq have a different offset (25mm), a different pcd (the studs are on a different radius by about 1.5mm), and the cetre hole is a different size - which is important to locate the wheel in the center and take the load (not the studs!)

So - how much is your life/car worth?

BTW - V6 conversions put the rack behind, better steering, no bump steer and don't rip the treads of the front tyres as the rod shop setups do

Im not too sure about the style of stud pattern as you say one is metric and one is imperial im not saying your wrong but i thought that the stud patterns were actually differernt in the fact that you couldn fit a hq rim onto a commodore being the stud pattern gap is larger by a couple of mil. I might be wrong myself so if anyone else knows the "correct" answer please let both myself and sammy know. thanks'

if ya want more inches, stroke it

The PCD of a commodore is 5x120mm and for the hq-wb is 5x120.6mm so they will fit as evident with people swapping rims etc. The problem is putting a wheel of one on the other stresses the stud and your wheels will end up in a paddock while your diff is looking at the stars. Hope this helps clear a few things up.
