Question Magnesium wheels

BBS has some mag. wheels that they say are meant for the track only. What about street use? Anybody got experience with these???

I have used magnesium wheels in the past on my Audi.

Magnesium is a brittle material and once it's cracked, it's difficult/impossible to find a welder to fix the rim correctly.

Also, magnesium wheels theoretically have an expiration date.

Is there a particular reason you want to run magnesium? There are other wheels out there that are strong and lightweight.

Porsche used/sold mg wheels on certain variants of the euro 964 carrera rs for street use .
They where a good compromise between strength and durability .
I personally would have no problem using even a used set on a weekend toy , but the cost of replacement would probably make them unrealistic for a daily driver .
You could get a few good years out of the bbs ones as they are a quality wheel .
The good news is, replacements will be held on stock by bbs .
The bad news is , bbs racing may have no stock and will not retool due to newer designs .

The same as any wheel I guess ...


If every last ounce of unsprung weight matters , go for it .
Otherwise , compromise on good quality lightweight al alloy forged wheels ...

I've seen some mag. centers for sale that would bolt into the sport design wheels I have. Thought it would be a neat way to lose a lot of weight. The cast centers are extremely heavy. It sounds like it would be risky to buy used.

the term 'fragile' comes to mind. I don't need that, thanks.

Did you check the weights to see how much you would save ?
On the stock 7.5&9x17 964 wheels , the euro rs saved a combined 23lbs .
On the set of 4 one piece mg wheels ....

As I said , I wouldn't have a problem with them .
I know beetles that are still running mag wheels made in the late sixties .
And 964s running mag wheels made in the early nineties .

The problem is replacements should you damage one ....
The last set of BRMs I saw for sale where 15k , and the last set of speedlines I saw for sale where 10k ......

A little to much to risk on a daily

The BBS web site still lists these wheels/ centers- E28. And I forgot to weigh mine while I had them apart. I'd be going from one extreme to another and I like extremes, especially when adding lightness!
