H&R 40555572 TRAK+ Wheel Adapters 5x112 66.5CB 12x1.5 Pair

The H&R TRAK+ Wheel Adapters (40555572) are hubcentric wheel adapters designed to adapt wheels with a different bolt pattern to your vehicle's hub. Engineered in Germany and sold as a pair, these adapters feature a 5x112 bolt pattern with a 66.5mm center bore and 12x1.5 thread pitch on the hub side, making them compatible with Mercedes-Benz hub specifications. A different bolt pattern is presented on the wheel-facing side, allowing fitment of wheels from a different vehicle make or model.

Like all H&R TRAK+ products, these adapters are fully hubcentric with a full-contact hub interface — mirroring the factory hub geometry for even load force distribution and strong lateral support. They are manufactured from a proprietary aluminum/magnesium alloy specifically developed for H&R, delivering higher tensile strength than standard 6061-T6 billet aluminum while weighing significantly less than a comparable steel unit. A hard-anodized finish provides lasting corrosion resistance and durability.

Beyond enabling bolt pattern changes, TRAK+ adapters also widen your vehicle's track width, improving stance and filling fender space for a cleaner, more aggressive look. The wider track lowers the roll center and increases lateral stability for improved cornering performance — benefits whether driving daily or on the track.
