H&R 40575571 TRAK+ Hubcentric Wheel Adapters 5x120 to 5x120 72.5mm Center Bore (Pair)

The H&R TRAK+ Wheel Adapters (Part #40575571) are precision-engineered hubcentric adapters designed to adapt BMW wheels with a 5x120 bolt pattern, 72.5mm center bore, and 12x1.5 thread pitch. Sold as a pair, these adapters allow fitment of wheels from a different vehicle make or model while maintaining the hubcentric design H&R is known for — ensuring a safe, vibration-free fit.

Unlike basic slip-on spacers, TRAK+ Wheel Adapters mount to the vehicle hub just like a standard TRAK+ DRM Series spacer, then present a different bolt pattern on the wheel-facing side. This allows non-standard bolt pattern wheels to be fitted without compromising the integrity or balance of the hub assembly.

Key Features:

• Hubcentric design — fits precisely to the vehicle hub for a balanced, rattle-free installation
• 5x120 bolt pattern with 72.5mm center bore and 12x1.5 thread pitch — designed for BMW wheel applications
• Sold as a pair — two adapters included per order
• Proprietary aluminum/magnesium alloy construction — up to 70% lighter than a comparable steel product
• Hard anodized finish — provides a tough, corrosion-resistant surface for long-term durability
• Maximizes vehicle track width — improves lateral stability, lowers roll center, and enhances handling
• Winter-friendly — suitable for use with snow tires and dedicated winter wheels

H&R TRAK+ Series Overview:

• DR Series (10–40mm track widening) — fits between wheel and hub; requires longer wheel bolts (sold separately)
• DRS Series (10–40mm track widening) — fits between wheel and hub; longer wheel studs included
• DRA Series (40–60mm track widening) — bolts to hub with included special wheel bolts; provides new threaded holes

H&R TRAK+ Wheel Adapters are the ideal solution for enthusiasts looking to run wheels with a different bolt pattern while retaining the premium fitment and safety standards expected from H&R. Whether building a track car or a show-quality street build, the TRAK+ adapter delivers the fitment precision and build quality to match.
