I think the centerline style would limit brake cooling and heat up the wheel bearing and wheel bearing grease.
we ran a similar set up on our road race karmann ghia with ERCO's and 4 lug porsche brakes all around. even in the enduro races we had no problems.
i will see if i can dig up some pics of the ERCO's on the bug and scan them.seien Sie größer, als Sie erscheinen

At the end of the day, if you ever have to deal with a magnesium fire you're probably not going to care whether you call it "flammable" or a "combustible metal"...

I watched my friend who races motorcycles, and whose dad is a former AMA champ, and sometimes Mg wheels would get bent and destroyed just going off track, not even wrecking, just riding in the pot marked ground.
And they were screwed up in wrecks.
I'd stay with a lightweight, cheaper yet still strong forged aluminum wheel.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.

I think with wheels like that it would either bit hit or miss. BBS and Dymag are some of the only companies that have made good wheels out of magnesium and they are really, really expensive.
A good example are the OEM CSL wheels made by BBS, which were entirely magnesium alloy and cost somewhere around $6000+ if you can find them. And then there are the Dymag magnesium and carbon fiber wheels which go for a similar price and are a little easier to come by.
But either way, magnesium is really light, but very reactive and soft making it very difficult to properly alloy it and manufacture it. Get the manufacturing and alloy percentages wrong and they bend on the first small pothole you hit.
For the value and strength, forged aluminum wheels are so much better. Half the price of the magnesium wheels and much stronger. I had a Toyota 4-runner plow into my car right at the rear wheel and the BBS RG-R wheel on my car was straight with the exception of a tear in the lip. In contrast, that collision tore the entire wheel off the SUV.

Also, list price on them is $611.01 for the front, and $638.91 for the rear.
M3 CSL Wheels
8.5" front- 36-11-2-282-650
9.5" rear - 36-11-2-282-999
M3 Comp Package Wheels
8.0" front- 36-11-2-282-895
9.5" rear - 36-11-2-282-999
As you can see, the wheel part number is the same for the rear 9.5 wheels. They are not Magnesium. And certainly not $6,000.00!

I was confused after reading an article where magnesium wheels were mentioned on a CSL. As well as lots of damn online rumors.
Adding to the confusion, BBS does make magnesium wheels that look very similar to CSL wheels at $1600 a piece:
