So what is the weight of these new lightest Apex wheels?

The lightness and strength appear key aspects of these wheels however there is no mention of actual weights in the write up? Did I miss it or is it in the vids that I haven't watched yet. Apologies if I have missed it.

The weight is somewhere, I saw ir a couple days ago. From what I remember was low-ish 19lbs.

Thanks! I missed that. Guess will have to wait for the individual weight information for various sizes.

IMHO unsprung weight affects how the car rides just going over bumps and steering even on the street.

Those 18s are great for the OGM2, unfortunately they won't fit over the big M2C brake calipers.

If you look at the fitment table on their website they have weights listed for most of the sizes

Weight notes:

I'm working on getting the full table images hosted for both designs so you guys can easily see and compare weights per size and so on. I'll update the OP when I have both images hosted.

Thanks for the feedback! I had actually brought up an OEM/OEM+ rear 10" M2 wheel option in the past with our team as a Flow Formed wheel, but the project was sidelined to focus on these forged wheels. If others watching this thread would be interested in a setup that is very similar to stock rear widths and offsets, please let me know. This kind of feedback does help drive our decisions to produce wheels in various sizes and I'd be very interested to hear if the community would be interested in a spec similar to OE specs.

My question for you - in terms of rear offset would you prefer an exact replication of the OE offset ie: 40? or something slightly lower in the et36-8 range for a bit more aggression while still fitting OE tires?

One of the benefits of our forged production is that it allows us to make smaller batches of fitments more easily than our flow formed lines so we can be a bit more flexible where production is concerned.

Maybe one day you guys will make a wheel for pure beauty instead of for heavy-duty race applications.

And that might be an interesting figure; what percentage of your customers buy your wheels for the street vs the track?
Our focus has always been strong and lightweight wheels that perform on the track, but I would really love to see the full breakdown of track/vs street use both with the initial buyer and over the life of the wheel. With our resources, the weight and the strength of the wheels are always what we focus on and this drives the final designs. Maybe some of our future options will appease your tastes, but for now we're going to stick to giving our customers designs driven by performance.

Very excited about the weight difference between the lines as shown above. Upping the load rating compared to our flow formed wheels and saving weight at the same time was a tough goal, but it was an important one for us.

It's interesting to note that the inner lip for the Sprint line wheels is even stronger than our classic forged wheels with the higher load rating. Load rating measures the strength of the spokes/face, and its resistance to spoke failure. There is no equivalent standardized measurement for the lip strength & many companies don't focus on the inner lip, but if a wheel is going to bend or fail the inner lip will likely be where the failure occurs as it is unsupported. We spent a ton of resources engineering a better inner lip to reduce the chances of bends and failures even though that isn't reflected in the final load rating.

You can learn more about these changes here:

"My question for you - in terms of rear offset would you prefer an exact replication of the OE offset ie: 40? or something slightly lower in the et36-8 range for a bit more aggression while still fitting OE tires?"

I really like the Cup2 240* tires "CS" in stock size, they stick and are still playful and I don't want to stretch them on wider rims.

Personally I'm ok with stock offsets but a few mm like ET 38 is ok too. What I've found is that too much poke with sticky tires means fenders with road rash. It's not as much of an issue on the track but in the mountain twisties it happens a lot. No amount of xpel can completely protect from sharp gravel.

IMHO the Edelweiss offsets are just a little bit too aggressive at ET20 and ET33. I'm sure people with fat coilovers might disagree. You only have to analyze the popularity of the stock BMW 763M wheels to see that there is a huge street market for a near stock size light forged wheel. I think with a super light wheel like the one you're proposing that competes with the 763s would sell like hotcakes!

I would be very interested in this. Either et40 or something in the 36-38 ballpark as you mentioned.

For those of you who would like a better look at these new wheels, we have a gallery thread showcasing our photoshoot of the black M2 competition on our 18" VS-5RS wheels. Heres a sneak peek:

+1 on the stock/close to stock rears. I prefer a less stretched look and +38 may just be perfect without rubbing and poke.

The thing is that if you run the car at stock height +40 on the back with Cup2s is very close to flush already.

VS-5RS in stock or as close to stock 763m offsets as possible in the 19's for M2c, and I'm in for spring group buy.
I'd personally rather running a spacer if I was trying to dial in "perfection" then try to get aggressive with offsets.

Personal opinion as you say and I get your point about maximising aggressive offsets however the reality is having the correct offset to match barrel width, tyre choice and clearance without spacers is the better option.

Yep, I'm totally with you.. I absolutely would rather the right rim with offset .
I personally think that 19x9.5 et22 is great for front right.. and hope there is a 36ish option rear.

Specification Tables Added

We've added the full tables of incoming fitments and their specifications/ETAs to the OP. As you can see, this is a massive range of wheels that we will be bringing to market over a short time frame and this is only the beginning! Fitments that are not a part of the current ongoing Group Buy will have their own associated Group Buys prior to their arrival.

Thanks for all the feedback about OEM+ rear offsets and options. Our notepads are out!

19x10 ET36-40 question/APEX follow-up

Another question for the M2 community, does anyone see the value of a 19x10 ET40 wheel run as a square wheel setup with large front spacers? These wheels would be a direct fit in the rear obviously and require 12-15mm front spacers and additional negative camber to fit in the front, but they would give M2 competition customers the ability to run a square/rotatable setup without the rear alignment adjustments that the lower offset 19x10" wheel options require.

I'm interested to hear everyone's thoughts!

-Tom

Tom, is there a combination of either 18x9.5 F and 18x10.5 R or square 18x10 (with/without spacers) that you have that will fit on a lowered (Msport coils) OG M2 without requiring additional aftermarket camber adjustment? I love the look of these wheels and would really like to run them on my car.
