APEX | NEW 19” EC-7 & SM-10 M2 & M2 Competition Wheels


M2 Competition: The Enthusiasts BMW

With modern BMWs growing ever larger, heavier and more complex with each successive generation, the F87 M2 and M2 Competiton have struck a balance between modern turbocharged power and the classic brand-defining compact packaging and balanced handling that defined their predecessors. This sweet spot has not gone unnoticed within the BMW enthusiast community with many owners falling in love with their M2. BMW also went beyond their past brake designs with the move to the Competition models by mounting huge brakes up front to handle the additional load of an S55 powered car hurtling into braking zones. With the 2NH steel brakes being standard in the US, 18” wheels were no longer an option. We knew 19s would be the way forward with the Competition cars and were excited to plan aggressive widths with offsets made specifically for this chassis. The EC-7s were born to clear massive brakes and their classic looks naturally lent themselves to the M2 chassis which made them the obvious choice for our M2 Competition wheels.

EC-7 development:

You asked, we listened! We're excited to announce that we've developed an M2C-specific track setup that clears the new 2NH 400mm front/380mm rear factory big brake setup. Since no 18" wheel can fit over this monstrous brake setup, 19" wheels are required. Through community feedback, we decided to produce these fitments in our popular EC-7 design in widths and offsets that were specifically designed with the goal of maximizing tire width under the fenders with little to no modifications.

We referenced our existing 18” wheel specifications created for the standard M2 (18x9.5” ET28 / 18x10.5” ET40), and after much discussion and research, have decided to make a small change to the rear wheel offset that you’ll appreciate. Many M2 enthusiasts expressed concern with rear fender clearance especially with tire models that run wide. Since our mission was to provide M2 Competition owners with 19” wheel solutions that properly accommodated popular track and race tire compounds, we decided to raise the rear offset from ET40 to ET45. This small but meaningful change in offset moved the rear wheels 5mm inboard where there is room to spare while maintaining a flush fitment in relation to the fenders. The result is wheel specifications tailored for 265/30-19 front and 295/30-19 rear tires. Other staggered tire combinations will work but many popular r-compounds like Toyo R888-R, Michelin Sport Cup2, and Pirelli Trofeo R are only available in this particular front and rear size combination.

M2 CS: CCB Clearances

The announcement of the M2CS was no surprise to BMW enthusiasts. A final high-performance model to round out the top of the M2 line seemed inevitable but was still a welcome addition. Beyond the power bump, the optional ceramic brakes caught our eye. As the first M2 to be equipped with MCCBs, we wanted to ensure our wheels cleared these brakes with ease to give M2 CS owners an aftermarket option beyond their factory 763M wheels. With templates built from in-house laser scans powered by Creaform, we were able to confirm that our EC-7s and new SM-10s cleared these optional carbon brakes giving CS owners an easy and affordable way to increase grip front and rear.


SM-10s and the M2: Flow Forming Evolved

The EC-7s in our M2 Competition specification proved to be even more popular than we initially anticipated. As more and more of our customers expressed their appreciation for a wider wheel fitment optimized for their M2, we knew the community would embrace an additional design option in these sizes. Our SM-10 from the Evolution Line was the natural choice as it mirrored the EC-7’s excellent spoke-side brake clearance while bringing features normally reserved for forged wheels down to a flow-formed price point. Knurled bead seats keep tires from slipping on the wheels during hard braking and acceleration helping to keep wheelsets balanced and smooth both on track and on the drive home. Side spoke milling helps keep the weight of these wheels low and a redesigned inner lip reinforces the wheel in the most critical area of the barrel to reduce bends from offtrack excursions or unexpected potholes on the street. These are fantastic features for enthusiasts looking for the ideal dual-duty setup. Beyond the technical details, the SM-10’s modern design was well suited to the M2 chassis and has us excited for the future of APEX wheels on the M2 and M2 competition chassis!

Fitment Recommendations & Tire Availability




Staggered vs. Rotatable Square Configurations

As defined in the chart above, we anticipate the most popular setup to be the staggered wheel fitment wrapped in 265/295 tires. There are pros and cons of both staggered and square configurations, and a laundry list of contributing factors to conclude which is superior like chassis type, suspension components, alignment settings, HP and TQ figures, whether or not aero is present, etc., so for the sake of brevity lets keep the comparison high level.

Earlier generations like the E36, E46, and even the E9X M3 are typically better suited running a rotatable square setup. Not only does the ability to rotate wheels and tires on all four corners of the car have a dramatic impact on the seasonal tire budget, but these chassis also respond very well to square configurations from a performance perspective. Squaring things up is an easy way to dial out unwanted understeer while improving turn-in, and it often results in a more neutral handling experience overall. Square fitments can limit your tire width, as you are bound to what you can manage to fit under the narrower front fender arches. With the E36 (S50/S52), E46 (S54) and E9X (S65) M3 generations, the respective naturally aspirated power plants are not pumping out overwhelming amounts of horsepower or torque, therefore, with negative camber dialed in enthusiasts are able to stuff compounds that are plenty wide under the front fenders, and the rears simply follow suit. In short, by going with a rotatable square setup for the aforementioned chassis, you really aren't sacrificing rear end grip to gain all of the benefits square fitments have to offer.

Enter the F8X M generation which scavenges power through forced induction, the conversation becomes a little more interesting. It is up to the driver to decide which wheel and tire configuration best suit his/her personal skill level behind the wheel, driving style, seasonal budget, and ultimately goals and intentions when attending HPDE's. These cars can make some serious power with very simple modifications like a tune, so rear end grip becomes more of a concern. While one driver piloting an F8X M is perfectly satisfied running 275's on all four corners of the car to gain all of the benefits of a square setup, another driver in pursuit of shaving down lap times or finishing on the podium will prioritize maximizing front and rear end grip at all costs. As they say, big HP figures look attractive on paper, but you have to be able to put that power down to the pavement. This is most noticeable when applying throttle on corner exit, and cars like the Mustang GT350 and Camaro ZL1 1LE find themselves in the same predicament.

The last major contributing factor is tire availability. With 18" wheels, there is an overwhelming amount of support from tire manufactures, and for many years this diameter (and smaller) was the primary focus for manufacturers offering track and race compounds. As the industry shifts to larger brake setups and in turn larger diameter wheels, tire manufacturers are slowly expanding their 19"+ offerings. At the end of the day, you can have the perfect wheel specifications, but they are of no value to you if there aren't tires to choose from. Tire availability or lack thereof in your desired compound may influence your decision you to run a square or staggered configuration. The good news is that we are offering both solutions.

We took the liberty of listing tire options in each of the respective configurations with an emphasis on performance street tires, r-compounds, semi slicks, and racing slicks. We are really hoping more extreme summer and r-compounds become available in the appropriate 19" sizes. If we missed anything, just let us know and we will edit the list.

Although these tire sizes on paper are a little slimmer than we would like for our M2 specific 9.5"/10.5" wheels, the fact is the RE-71R's run wider than most street tires, so they would actually mate up to our M2 specific wheels quite well. The wider wheel is only going to support the sidewalls that much better.

F: EC-7 19x9.5" ET28 - 255/35-19 RE-71R
R: EC-7 19x10.5" ET40 - 275/35-19 RE-71R

► 4/25/19 MAJOR THREAD UPDATE



This week we received our first official set of sample wheels for the M2 Competition Group Buy. We have been incredibly excited to finally have the chance to show these stunning EC-7 wheels off to the community, and today we are delighted to present some of the outstanding edits from our latest photo shoot.

Our goal heading into the testing phase for the M2 Competition was to validate our fitment, and to determine what modifications may be needed when using a very aggressive tire compound on the F87. This car features our new 19x9.5” ET28 and 19x10.5” ET45 EC-7 wheels, paired with 265/30-19 and 295/30-19 Toyo

In this write-up, we will take you through our testing process, giving you a behind the scenes glimpse into what it takes to bring these purpose-built wheels to production. We are thrilled at the way these new M2 Competition specific wheels turned out, and look forward to seeing them in the wild in the foreseeable future.

M2 Competition Stock Wheels:

The M2 Competition was released with the 19” 788M wheels in the following fitment:

Front: 19x9” ET29
Rear: 19x10” ET40

Though this fitment is a great improvement over a standard 2 series, they are not designed to maximum the potential tires that can be used on this car, leading to better performance. With the massive torque of the new S55 engine, wider tires are needed to properly put that power to the ground. The stock 19x9” and 19x10” wheels are not wide enough to properly support the side wall of 265/30-19 and 295/30-19 tires, which is our recommended size for this chassis.













M2 Competition Stock Brake Clearance:

The release of the M2 Competition brought many improvements over the standard M2, including new brakes. BMW released the M2C with the new monstrous 2NH 400mm front/380mm rear factory big brake setup, making it impossible to use 18” wheels.

When reviewing the stock 788M 19” wheels, we found that even though they do clear the brakes, clearances do appear to be quite tight. The F8X M3/M4 with the carbon ceramic brakes did have a similar issue, and some customers did experience small debris or a larger rock becoming lodged between the caliper and the wheel. Our goal with the 19” EC-7 wheels was to improve this brake clearance.







APEX 19” EC-7 M2 Fitment:

Our new 19” EC-7 wheels feature the following fitment for the M2 and M2 Competition:

Front: 19x9.5” ET28
Rear: 19x10.5” ET45

Our original plan was to mimic our current 18” FL-5 fitments for the M2; 9.5” ET28 & 10.5” ET40. However, after further research and feedback from the community, we ultimately decided to change the rear offset to ET45. This small changed moved the rear wheels inboard by 5mm, still allowing proper inner clearance while accommodating aggressive 295 rear tires without the need to modify the car. The end result is a fantastic fitment, specifically tailored to run 265/30-19 and 295/30-19 tires.

We chose to test these wheels with aggressive Toyo R888R tires, to showcase what the fitment will look like when running a track focused R-compound. Up front, the 19x9.5” ET28 paired with 265/30-19 tires is quite aggressive and a touch of negative camber is recommended to avoid rubbing under compression. However, many drivers running a street focused tire, such as a Michelin Pilot Sport 4S, may be able to use this fitment with minimal adjustment to their alignment. The rear 19x10.5” ET45 is perfectly suited for the 295/30-19 tires, and is a direct fit in most cases.

This fitment is a great solution for those looking to maximize their performance, while having a spacerless fitment that sits flush in relation to the fenders.























APEX 19” EC-7 M2 Brake Clearance:

The EC-7 wheels has been known to provide some of the best brake clearance in the industry, with our 18” wheels clearing even the massive Brembo 380mm BBK. This brake clearance extends to our 19” wheels, which clear the new 2NH brakes on the M2 Competition even better than the stock 788M wheels.

As you can see in our testing, the 19” EC-7’s provide ample brake clearance both in regards to the spokes and the barrel. By further improving this clearance over the stock wheels, you can mitigate the risk of debris or rocks damaging your calipers or your wheels.



















Exterior Shots:

We love the way our Race Silver EC-7 wheels complemented the Long Beach Blue paint on this new M2 Competition. Let us know what you think of the new 19” EC-7 M2C specific fitments:

Have been an Apex fan for quite a while and the 19” EC-7 is just the ticket for my new M2C. Cups 2s are sitting in the garage waiting but alas your site suggests that my wheel of choice is not anticipated to arrive until LATE APRIL!!! That’s nuts!

I’m tying to hold out but my other choices are on the shelf ready for delivery. It wold be much appreciated if you could push production times up. It would be good to have M2C specific wheels available before the car goes out of production next year!

You may want to check Turner Motorsports for Apex wheels. Was on their site yesterday and they showed several models in stock.

Theres literally plenty of options in all different sizes lol. Spend the money on cup 2's or toyos or run ps4s if you're just using on the street. 265/30 265/35 255/35 all works in the front. 295/30 305/30 works in the rear. All of which are readily available in said brands listed above. You could get the tires faster then wheels at this point probably. You want MORE options? You bought the wrong car then. Buy a Honda Civic, then you will have 20 pages of tire options in a 205/55/16

I had a 19” track setup the last two years and ran Trofeo’s, Cup 2, R888R, RE-71R, and R7s, and am going back to 18s so I can run NT01, AR1, A052, Toyo RR, and Pirelli slicks.

Crazy thing is going to the forged EC-7 18’s with A052’s will save 30lbs of rotational unsprung weight, vs my 19” VMR’s (1/2lb heavier per wheel than 19” EC-7) and RE-71Rs.

That’s nothing to sneeze at!

It's fine for the steet, that's why I specified 'track tires'. Keep in mind we're in the track / autocross / dragstrip forum There are no decent budget or even mid price-range track tires in the right sizes. And no slicks (not that I run them). None of this is their fault of course, I just wouldn't call it 'plenty'.

Btw, I do run my RSX Type-S on stock 16" rims and yes, the tire selection rocks

Has anyone ran 265/35/19 and 295/30/19 setup with Öhlins R&T and GC camber plates on the stickier track rubber? Just want to see if that sizing works without rubbing and what the offsets they used were. Finally if they used spacers or not at all.

I believe I read the front 35 aspect ratio will rub on the R&T and others due to dropped height due and the front conical spring design. Spacers will probably fix the spring rub issue but I'm not certain if the 265/35will ultimately avoid rubbing the liner. Obviously greater amount of negative camber you dial will help.

I run a square 265/35 x19 setup on the EC-7, with the Ohlins R&T, using the Bridgestone RE-71r. Camber is 2.5 F and 1.5 R. I'm using a 5 mm spacer in front for clearance; rears do not need a spacer. No rubbing. I also run the GC camber plates
