The BimmerWorld View:
A 9.5" is a very smart fit for the F87 M2 even though it might seem like a step down from the stock 10.0" rear wheel. With a 9.5 you can still fit up to a 275 width tire which is still a lot of tire. The 9.5 fits better under the M2 bodywork than the 10.0 wheels. EC7 wheels look great on the M2 and the spoke and barrel design give generous room for the stock brakes.Spacers for the front wheels are required.
An optimized car setup begins with the perfect wheel fitment. Without utilizing perfect wheel offsets and maximum tire widths, you're compromising the performance potential of your BMW. Because of this fact, the EC-7 offers three unique face profiles ranging from shallow to deep concavity, and this results in 13 unique 18" sizes. This wide range of fitments allows for vehicle-specific caliper clearance, offsets, and tire widths, giving you the widest range of optimal setup possibilities.
The EC-7's spoke profile has been designed with a curve to provide additional caliper clearance, often clearing a BBK on applications where the ARC-8 could not - spacer-free! Note: In race applications, we still often choose to use spacers.
Another significant improvement from the EC-7 design is the increased barrel clearance that allows for the 18" version of this wheel to properly clear the Performance Friction 378mm Brake Kit. As with the rest of the APEX wheel line, EC-7 achieves its combination of strength and light weight through flow-forming technology. By flow-forming the wheel, weight is reduced in the barrel through a process sometimes referred to as "roll forging." Roll forging, while not the same as the traditional forging, is superior to regular casting. The rolling process occurs under extreme pressure, yielding a barrel that is stronger than a standard cast wheel, with certain material properties that are similar to a standard forged wheel. This added barrel strength allows for a reduction in overall wheel weight, while not sacrificing any of the strength you'd expect from durable flow-formed wheels.
Thanks to its lightweight barrel and robust face design, the EC-7 stands up well against the rigors of endurance racing, as well as your average street potholes.

- Accepts factory lug bolts, studs, or wheel locks
- Compatible with factory tire pressure monitor sensors (TPMS)
Priced as a set of 4. Apex wheel center caps included. BMW center caps sold separately.Front wheel spacers are required to clear the strut.
Without the spacers the front wheels will rub on the strut body. Spacer size will vary depending on the front strut brand - 5mm for stock struts, 12mm or more on coil overs. These wheels, like many wheels, are not compatible with 10mm wheel spacers. We recommend using 12mm spacers, as 10mm hubcentric spacers have inherent design limitations that prevent them from sitting flush. See below for product link.General Fitment Note:
these are sold as a race-fitment only and rubbing with bodywork or on suspension may occur depending on tire choice and suspension settings. We cannot verify fitment with every combination of wheel-tire-suspension. Verification of wheel fitment is the responsibility of the customer.
