It was closer to 41~42 pounds when I ran the numbers on paper. BMW, Apex, and tire manufacturers are all going to have some small variances in weight. Sadly, I’ll have to wait until next spring to find out myself.

Its not just weight, but rotational mass.

I think you can probably do that with the Apex 18x10.5 vs5rs with a 285. They required spacer for front clearance with 305 on the front but you may get away with it with a 285.

Even more importantly than both of those: UNSPRUNG mass.

Dang, these 930m wheels are cast and Chinese made?

Well anyone needing a quick way to get rid of their silly 19' cast Chinese made wheels (in black) can trade me for my 20", or let me take them off of your hands for a reasonable $ amount.

I jumped on a set of 826Ms with nearly new tires, TPMS, etc. I wanted to get 824Ms, but very hard to find those. I like the OEM look, and didn't want to deal with spacers and offsets right off the bat.

My weight savings will be exactly 4lbs for each front wheel and exactly 5 lbs for each rear wheel. Total of exactly 18.0 lbs.

Not very exciting, but it is something. (lets see if this rotating and unsprung thing is really noticeable. I'll get my lap times with 930Ms than with 826Ms and see if there is a difference.

But first I need to get my car - LOL.

I've heard the 824Ms are so close to the calipers that rocks can get stuck easily. The intricate designs of all the BMW wheels are so hard to clean I want something simpler, lighter and with better offsets.

Yes, I guess it is best not to mess with how tight the 824Ms are - I'm also not sure if that reduces airflow over the caliper/brakes and traps more heat on track.

I hear you on hard to clean wheels - I think 824Ms are prob the easiest followed by 826M. 930M seems to be impossible to clean

But I agree with you - give me a simple design any day.

Call me generic, but I will likely go Apex forged for summer and keep the OEM for some ridiculously oversized winter wheels. Love the VS-5RS on my g42.

That was my plan too. But today I just spent waaaay too much time cleaning the OEM wheels. My knees are telling me I should replace them with something easier to clean.

After 3 procedures on one knee and 2 on the other I chose this option

Yeah, I usually kneel on a garden pad thingie, but may move to a stool.

Also, what are those wheels? They showed up in the M2 CS thread and I couldn't figure out what they were.

2019 M240i factory wheels. I believe, but not certain, 792M.

Good luck with the knees. That stool is a blessing.

Ah, oem m240i was what I needed. They are 719M. TY.

What sucks about the cast wheel is that it actually looks pretty damn amazing. These wheels are the best ones in the current lineup design-wise. Like, by a long shot. Look at the concavity and the design elements, they're sick.

They are clones of the 825M, which IIRC are forged, so you could switch to those if you like the spoke design.

AFAIK, the 825Ms do not come in bicolor, though.

Overall I like the design, but it is a sumbitch to clean.

Any weight info on 825Ms?

Just stumbled upon this video that confirms BMW M wheels are forged with exception of the cost cutting on the G87. Style 826M wheels however which come on the G80/2 are forged. They're made by wheel manufacturer Super Alloy Industrial (SAI) in Taiwan.

You can see the 826M wheels 8m25s into the video at their forged alloy wheel factory.

They also have a picture of the 826M wheels in their Technology section under Step 4, Painting.

Another cool thing is they also manufacture the Toyota Supra wheels which they have listed under BMW.

BMW
Bicolored 10-spoke forged wheel tailored for the Supra, the first sports car co-developed by BMW and Toyota.

Also found this PDF where they showcase the 826M wheel as a net shape forged wheel.

Net shape wheels are forged as close as possible to the actual design decreasing the amount of final processing needed for high volume orders and also decreases cost. They are however still fully forged wheels.

Yes, SAI seems to have replaced Fuchs for G8x M cars. Except the M2, lolz

SAI also makes the forged F9x M5/M6 M Performance wheels (with the holes in the spokes) and G2x 3/4 Series.
