I hear BMW wheels have the same PCD as Commodore wheels.

Are there any with similar offset to Torana wheels?

A BMW wheel I know of for sale has the following stamped into it: 1179030 6J15 HZ E20 P 616 8A 26 90

The owner says it's 6 inch wide and 15 inch diameter, I can see this in the details, would this be a 20P offset?

I only intend to use it as a spare anyway.

Some are close, but many sit further out and can foul on the outer guards (especially if the car is low) 20P sounds about right I think, aren't Commodores normally somewhere around 40?

These are BMW wheels on the green UC.

The green one is a UC?

These are 225/50/16 tyres on 16x7" ROH Chicanes (BMW offset of some sort) that I had on my VK with factory VL disc brake diff:


Machined around 8mm off the hub mounting face to attempt to get them in a bit, and the rear guards are rolled. Was OK at standard height but couldn't get it to work once lowered so I gave up. In the pic above the car is at standard height in the rear with the diff dead centre using the adjustable panhard rod. Fronts just cleared OK if you have a bit of negative camber.

Yes it is p20 offset.

Here is to links to BMW wheels
This one is the styles, size and offsets,

This one narrows it down to which size you choose.
As it is in German , use Felge for rim size.

See how go.

That site stopped working for some reason.

A question on the stock rims, what type of nuts do they take, stock conical ones or flat face mag style nuts?

Standard tapered nuts on all the ones I've seen

Cheers, I've got Commo stockies on atm and thinking of picking up a cheap set of BMW wheels with good rubber to spruce up the looks till I decide on some decent mags, I'm in no hurry.

I'm wondering if I can use the same nuts, they are dark so I'll probably get another set to suit.

The taper is a standard angle for all wheel nuts right?

Good question, I've never thought about it but I presume so as I've never had any difficulties with mixing and matching.

I picked up a set of BMW 15 X 6.5 wheels

Problem, I put on the passenger side front wheel I could see when I spun it around the lead weight on the inner rim strikes the ball joint plate on the upper control arm.

I went for a little drive thinking maybe with the weight of the car on it, it may be ok. It was making such a racket.

I took off the wheel, then I thought I'd check out the driver side front. I put the wheel on and it clears the lead weight.

I tried one of the other BMW wheels on the passenger side - same problem.

What's going on here? Is one side different to the other? I'm thinking to remove the weight but I don't want to drive around on unbalanced wheels. I was wondering if I can shave away enough of the ball joint plate but not sure how much I'll end up removing and if it may affect the integrity.

I guess I could get some 16" rims.

Also the centre hole of the BMW wheel doesn't sit on the hub as snug as the stock Commo wheel does, there's quite a bit of play, is this of concern?

[StephenSLR]

I've been thinking, I recall my previous mags many years back had adhesive weights stuck on.

I haven't seen any in years, do they still use them or are there only certain applications for them?

If I could get away with the weights stuck on the inside of the rim rather than on the lip, this would solve my problem.

I've finally got around to posting a pic. These'll do till I figure out what wheels to get, I'm not too happy with most Commo wheels, not much variety apart from 5 spokes, I'm inclined to save for the 15" hotwires but that'll take me a while.

Got these on ebay and at $40 a pop are a damn sight prettier than the Commo stocks I was driving around in.

These ones are easy ash chop!

Yeh they cost me 30$.... now just gotta find another two lol

[StephenSLR]

are you running commodore brakes /hubs or are they HQ

Commodore stud pattern on the rear (BW diff) and Hoppers kit on the front with Commo stud pattern.

If they are HQ, Commodore/BMW are NOT a good idea

When I had the diff installed I supplied 2 Commo wheels and asked for Commo stud pattern. The guy rings me saying the nuts won't fit because they're Commo nuts. He put in HQ studs thinking I was getting HQ brakes at the front. He replaced them. What I noticed when I had the Commo stockies on was the locator was a press fit on one side but the other locator was a touch smaller in diameter, though not even a millimeter. Should I be concerned?

whats worse is that with BMW wheels the hub is larger

There's a 3mm difference in diameter but I have Commo/BMW hub rings.

so all the load is on the studs

I believe that is how it's meant to be - discussed more here: http://www.gmh-toran...6-hub-locaters/

jag wheels can be used (with hub ring locators) but offset can still be a prob

The offset on mine are similar to Commo, 42P I believe hence why I don't plan on having them on permanently. I can't put on the centre caps as the rotor cap pokes through the rim and on the rear it's almost the opposite with the rim barely on the locator.
