Product Description

The H&R SK-011 is a complete TRAK+ DR Series wheel spacer and bolt kit for the 2015-2019 BMW M3 (F80), M4 Coupe (F82), and M4 Convertible (F83). This kit includes 12mm spacers for the front axle and 15mm spacers for the rear axle along with all required extended wheel bolts, providing the perfect staggered spacing to push the factory wheels outward for an aggressive, flush-with-fender stance that eliminates the factory wheel gap. The hub-centric 72.5mm center bore ensures vibration-free fitment that matches the factory hub exactly.

H&R TRAK+ spacers are manufactured from a proprietary alloy specifically developed by H&R that is lighter and has a higher tensile strength than standard 6061-T6 billet aluminum, delivering superior durability in a lighter package. The DR Series design fits between the wheel and hub, using the included extended wheel bolts to secure the wheel through the spacer and into the factory hub threads. This eliminates the guesswork of selecting the correct spacer width and bolt length separately -- the SK-011 kit is pre-configured specifically for the F8X M3/M4 platform. Beyond the visual improvement, the wider track increases lateral stability and improves cornering grip by leveraging a wider contact patch footprint. Verify that extended bolts do not interfere with ABS sensors or brake components by rotating the wheel by hand after installation. Made in Germany by H&R Special Springs.
