7.5mm Wheel Spacers with Integrated Hub Extenders - Black (Pair)

The new M3 & M4 use a unique notched hub. Since BMW wheels are hub-centric, it's important to use a hub extender when adding spacers, but this new, notched set up does not allow for standard hub extenders to be used. Turner Motorsport has created a wheel spacer especially for these vehicles with an integrated, notched hub extended that makes perfecting your fitment a snap.  Turner Motorsport has spent the last two decades striving for ultimate performance on the racetrack, and transferring the knowledge gained from winning races onto the street. Their line of BMW performance parts combines, high quality, great value, and most importantly, superior performance that will allow you to dial in your ride to suit your driving style and allow your BMW to live up to its full potential. These wheel spacers will help you perfect the fitment of your BMW, and ECS Tuning has a full line of wheel bolts and studs to complete the package. Sold as a pair. Features: Note: Your factory wheel bolts are typically 25mm in length. To safely install wheel spacers, be sure to select wheel bolts that are longer than stock by the correct amount. Wheel bolts that are too long may interfere with other parts inside the hub, such as ABS sensors or your parking brake mechanism. Wheel stud conversion kits are also available.
