QQ: what's latest status on magnesium wheels?!?

[rdollie]

Anybody have an update??

 

[MatthewAMEL]

In for info. Would love some lightweight OEM wheels.

Doesn't look promising. They may not have enough magnesium to produce aluminum parts soon.

The Car Shortage Is About To Get A Whole Lot Worse

A critical element in everything from engines to bodies is in short supply

That article may be true but I doubt caddy would advertise wheels they don't have

Back in 2015 Cadillac was talking about a Carbon Ceramic Brake option on the 3rd generation CTSV and it didn’t make it into production , so you never know what might happen .

We're they? I only remember when the chief engineer was debuting the V3 and said the steel brakes have come a long way in fade prevention and that was why they didn't offer it.

Wait...the tech bronze wheels are Mg?

 

[RDATLTE]

A friend somehow lucked into a set. I’m trying to get him to weight them and to see if they have a part number.

No. I have a set and they are aluminum.

 

[RDATLTE]

No. I have a set and they are aluminum.

Have you weighed them?

And just to be sure... @poor-sha yours don't have 'Mg' stamped on them anywhere?

Nope. There was a set of Mg proofs that ended up on eBay a while ago. I assume they were created for testing.

I’d love a set if they were available and would hold up.

Me too. Thanks for clarifying.

Thanks for weighing and posting. I think 26 lbs with tire is not bad at all.

Bet that's in Kg, because the front tire all by itself is 28lbs and the rear is 30lbs.

You’re right. I must’ve accidentally changed it to KG, you can see it in the photo.

If all this is true, then these aren't actually very light. 26.4kg = 58lbs. If the tire is 28lbs then that's a 30lb front wheel? Rather heavy. I recall the standard wheels are 29lbs front and bronze is a little heavier. So the mag ones might be a tiny bit lighter than the same bronze wheel design in aluminum, but not a big difference and no lighter than the standard polished or dark gray wheels.

 

[RDATLTE]

It looks like ~10lbs lighter for a rear as I believe this was without TPMS. Substantial enough to require a mag ride recalibration if put into production?

GM's supply chain issues turned into a win for them. They can charge for an upgraded wheel without it actually being Magnesium as originally promised.
