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. Yahua Performance has created a wheel spacer especially for these vehicles with an integrated, notched hub extended that makes perfecting your fitment a snap.?

Yahua Performance 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:

• Lightweight - excess material is removed to reduce unsprung weight while preserving strength
• Ingenious notch for easy removal, even on heavily corroded wheels
• Made to exacting specifications for great fitment
• Manufactured in the USA

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.
