Quick look at fitment with 19x11 with 305/30/19 goodyear 3r with -3.3 camber and 12.5mm spacer. Looking really tight. Have about 3mm between tire and strut.

Definitely. 18x10.5 ET18 is a specialty fitment primarily intended for track performance. Basically, the target with this wheel was to make it an easy direct fitment in the rear in terms of offset, and then use spacers/adjustments in the front as needed to gain clearance on the inner edge.

Anytime you're creating a square rotatable fitment, you can either optimize the width and offset for the front (generally a lower offset) or for the rear (typically higher offset). I prefer offering a higher offset option for a few reasons.

-Offset can always be reduced post-purchase with spacers, but you can't increase it. Spacers are nice because different customers can run different thicknesses depending on how much clearance their car needs. If you try to clear the front suspension with wheel offset alone, you have to make a wheel with an extremely aggressive low offset for the worst-case scenario builds that then punishes all others who want to run the fitment with a milder build.

-The front of the car is generally where it is easier/more beneficial for the car to run additional camber. This is often required with various fitments and adjustability means that it can adapt to different tire configurations more easily.

-The rear of the car has less camber adjustment options that also benefit performance. The eccentric bolts aren't consistent car to car in terms of what you can get and rear camber isn't as beneficial for these cars as front camber is for the track. The alternative to dialing in rear camber to tuck a tire is rolling and pulling your rear fenders for clearance, but this mod isn't reversible and is a drastic step most owners don't want to deal with. I prefer a fitment that may need spacers up front but lets you pull the parts off at the end of the day and go back to stock if you choose to do so.

Tom, thank you for the detailed and comprehensive response (most helpful). I intend to install the M4 CSL carrier for additional camber. This would push the wheel inward compared to the entire strut assembly shifting inward with the wheel. That said, the front would have limited clearance once the hub is installed on the vehicle.

Would you have recommendations for perhaps a factory spec M4 CSL/M3CS (G8X) which has less front strut clearance? The 10.5 'may' be excessive with the OEM suspension from what I am gathering.

Much appreciated!

Regards,

Lutfy

Not one that we've been able to bring into the office and scan which is what I need to be precise with a recommendation. I know I have a G82 M4 CSL running 19x10.5 ET18 square with 295/30-19 Hoosier R7s, but I don't know what spacers the shop that got the wheels, camber plates, and modified fender liners installed ended up using. I'll reach out to them and follow up If I can get feedback on the spacer they used, but here are some shots of that car on the 19x10.5 ET18s square.

The best place to pick a car color is on wheel threads. I just may copy this, with apologies. Gorgeousness

Here they are dusted after 2.5 hours on track…MP HAS factory installed height. First track day ever and no less than 4 people came over during the day to see the wheels which surprised me a bit being in New England, but they are clearly known. 2 GT3s were also running Apex.

Hi Tom, thank you for such a informative thread!

I am looking at the Apex G87 fitment guide and one recommended 19' staggered setup is:

Front Tire Size: 275/35-19
Rear Tire Size: 285/35-19

By doing this, the rear tires will be 7cm taller than the front ones. Would there be problems? Would I need spacer & camber if I go with this setup? Thanks!

No issues with the front/rear heights.

The wheel fitment those tires are recommended for is our 19x9.5 ET25 front/19x10.5 ET18 rear. I do recommend a 5mm spacer with those wheels if you want to match the factory front wheel fitment (factory wheel is 19x9.5 ET20). The spacers aren't required for brake clearance and most 275/35-19 tires would clear the suspension still without front spacers, but just to maintain the factory look of the front fitment 5mm spacers are recommended.

Specs:
Wheels: 19x10 ET12 front, 20x11 ET18 rear
Tires: OE Michelin PS4S, 275/35-19 front, 285/30-20 rear.

Hi Tom,

Looking for this set in black, what is the weight difference savings I could see going with these exact setup wheels? I do would like to reuse the OEM PS4S* if possible.

You can certainly reuse the OE tire sizes on those wheels. The weight comparison is a bit apples to oranges but:

OE 930M wheels: Reports are varying from what I can see on the specific wheel weights for these, so a bit of a grain of salt here but:

Front: 19x9.5 ET20, 27.5 lbs
Rear: 20x10.5 ET20, 31 lbs

Apex SM-10RS: Brushed Clear weights are what we list, add .2 - .3 of a lb in paint weight for other colors.

Front: 19x10 ET12, 20.2 lbs
Rear: 20x11 ET18, 21 lbs

The switch should net you ~ 34.6 lbs of weight reduction with brushed clear. Maybe 33.4 with other colors. You'll also gain a half-inch front and rear in wheel width which you can use later to run wider tires than the OE tires.

The wider tires will be slightly heavier depending on the specifics but will pay dividends in terms of performance.

Got my 18x10.5 18" Vs-5RS wheels installed today! They look fantastic, thanks Apex!

Mounted Nitto NT01 305/35R18 square. 5mm spacer up front, stock camber, seems to fit fine though only about 3mm between tire and strut tube. Can't wait to try this out on the track!

The only thing to note is the tight inner clearance between the front tires and fender liners with the 285/35-19 tires. You may get some liner rubbing around the radiator vents in parking lots at full steering lock. I haven't seen this on an M2 yet, but it was close in our testing with Michelins.

-Tom

I’ll be testing this exact front axle setup next week with the MP HAS at the default 10mm drop ride height. Will update everyone on how it goes.

MPerformance HAS lowered as far as they’ll go, but only 50 miles on it post install, and I haven’t done an alignment yet.

I do need to do something with the front liner vents…

Are these tires beefier than equivalently sized PS4S?

Thanks but that’s not what I’m asking. Didn’t phrase my question well. I wanna know if the 285 SuperCar 3 tires take up more space than 285 PS4S

[71dsp]

I don’t have any actual data, but I read somewhere that the GY SC3s were a tad wider. I do get rubbing on the fender liner vents with lots of steering input. Not sure if the PS4S get the same.

I can get some actual info when I take the wheels off to clean them.

ML-10RT now available for Pre-Order

The ML-10RT forged wheel started life as an engineering passion project. You brought it to life.

It’s the moment you’ve all been waiting for. The green flag has dropped and the Forged ML-10RT pre-sale is officially underway! Reserve your set now to ensure you receive wheels from the first production batch, and save 15% off + free shipping in the continental U.S. Due to extremely high demand, we expect a number of popular fitments and finishes to sell out, so act fast. Pre-order discounts are based on product availability, and are subject to change at any time. Please note we fulfill orders in chronological order, so the sooner you place your pre-order, the faster you will get your wheels.

Features

AN EVOLUTION OF PERFORMANCE - The ML-10RT honors the motorsport designs so many of us fell in love with during the golden era of Touring Car and Sports Car racing. However, its ancestry ends there. Our in-house engineering team pulled out all the stops to create a monoblock forged wheel that's lighter, stronger and stiffer than multi-piece wheels of the past. Utilizing the latest forging technology to offer an impeccable design, backed by Real Performance, at an obtainable price point.



SIDE-MILLED SPOKES - The ML-10RT incorporates Apex’s extra-deep, side-milled spokes. Any excess material that doesn’t add strength is carved out using a precision CNC ball cutter. Often deemed cost-prohibitive by others, this aggressive side-milling shaves critical weight, and adds a sharp contrast in the design of the center spoke area.

SPRINT INNER LIP - The ML-10RT borrows the race-proven Sprint Spec inner lip from our Sprint Line wheels, providing critical strength to the unsupported inner lip of the wheel. Adding 32% more material where it matters most. Don’t settle for under-engineered wheels, attack both the track and your cities potholes with confidence

10K TONS OF PRESSURE - To make our forged wheels the strongest we can, we applied as much pressure as possible using a 10,000 ton forge. This extreme pressure increases the strength of the aluminum by eliminating porosity and improving the grain structure.



TRUE MOTORSPORT BLANKS - Many companies use 3rd-party blanks intended for non-motorsport wheels which can severely limit sizes, concavity, spoke design, and critical brake clearance. We designed our very own blank profiles from scratch to give us total control over the final product.

INDEPENDENTLY TESTED - We don't rely solely on computer simulations or unverifiable in-house testing. We believe independent testing is critical to protect consumers in this unregulated industry. Our Touring Line wheels are independently tested by ITS at their Michigan facility following JWL standards but pushed to much higher loads and much longer durations.

MACHINED LIP - The ML-10RT is our first forged wheel to feature a machined lip, which really makes it a standout design within the Apex catalog. The lip in combination with the mesh center pays homage to the glory days of motorsport, and is sure to dramatically transform the look of any car. The best part - the machined lip has a gloss clear coat and doesn't require polishing.



VEHICLE SPECIFIC SPOKE PROFILES - The lipped design of the ML-10RT inherently limits brake clearance. Rather than making every fitment as conservative as possible, we utilized our extensive 3D vehicle scanning library to shrink wrap each fitment's spoke design around respective OEM and popular aftermarket brake kits. Leveraging our vehicle research and engineering team, we find a perfect balance of concavity and brake clearance.



BUILT FOR IMPACT SOCKETS - Don’t settle for wheels that require undersized tuner lugs or thin walled sockets. All Apex wheels accommodate over-sized race lugs and impact sockets to make swapping wheels lightning fast.

OEM CENTER CAP COMPATIBILITY - Love that OEM+ look? Us too. Our engineers went the extra mile and incorporated a flush mounted OEM center cap support into the ML-10RT. Whether you want to show off your included Apex center caps or stick with your OEM caps, the ML-10RT will seamlessly accept both.

LASER-ENGRAVED SPECS - As car enthusiasts ourselves, we know how frustrating it is to locate and decipher wheel specs that have been hastily marked on a wheel or become unreadable over time. Our Touring Line wheels have laser-engraved specs on the barrel, in plain sight, making them easy to find and read.



Pre-Order your set of ML-10RT today

Buy with confidence. With only a 25% deposit initially required for these wheels, you can Pre-Order today and lock in the deep discount and ensure you get your preferred fitment and finish early. Don’t miss your chance to be the among the first to run this all-new Apex design.

Not sure if we'll do the 19x10.5 ET18, but the 19x11 ET22 can be pre-ordered on the site now: https://apexwheels.com/vehicles/bmw/...ize=19x11-et22

You have to trick the configurator and plug in 4 19x11 ET22 rear wheels and 0 fronts, but I don't want customers with stock suspension buying the square 11s and assuming they'll fit right out of the gate.

Any plan to do 20X11 et18?

[LeggoRacing]

Ah fair point. Got it thanks. Have the vs5 in 11 on both m2 and Supra. Love the look so this would be a good add

Possibly, we're still evaluating producing 20s in general. I had wanted to launch with this wheel, but it wasn't possible on the faster timeline. For now it's just the 19s.

I'd encourage both of you to fill out this form if you do want us to pursue other fitments: https://apexwheels.com/pages/stock-notification

That lets us capture requests in an organized way and helps me put numbers to specific fitments.
