H&R 50625671 TRAK+ 25mm DRA Wheel Adapter Pair 5/100 - 57.1 CB Audi/VW

The H&R TRAK+ 50625671 is a 25mm DRA-series hubcentric wheel adapter designed to change a vehicle's bolt pattern, allowing wheels with a non-standard bolt pattern to be properly fitted. Sold as a pair, these adapters mount to the vehicle hub on the car side using an M14x1.5 thread and present a 5x114.3 bolt pattern with a 67.1mm center bore on the wheel side — making them ideal for fitting Audi and Volkswagen wheels (5/100 - 57.1 CB) to compatible applications.

As part of the DRA series, these adapters bolt directly to the hub using special included wheel bolts and provide new threaded holes on the wheel-facing side — no longer wheel bolts or stud swaps required. Like all H&R TRAK+ spacers and adapters, the hubcentric design ensures a full contact hub interface, matching factory tolerances for even load force distribution and proper lateral support.

• Hard anodized finish for long-lasting corrosion resistance and durability
• Maximizes track width for improved stance, lowered roll center, and increased lateral stability
• DRA series includes special mounting hardware — no separate wheel bolts required
• Engineered in Germany to OEM-level precision tolerances

Wheel Bolt Safety Guidelines:

• Verify minimum thread engagement before installation (minimum turns vary by bolt thread pitch)
• M12×1.25 requires a minimum of 8.0 turns (~10mm load-bearing shaft length)
• M12×1.50 requires a minimum of 6.5 turns (~10mm load-bearing shaft length)
• M14×1.50 requires a minimum of 7.5 turns (~12mm load-bearing shaft length)
• After installation, rotate wheel by hand to confirm full clearance — no contact with brake components or ABS sensors

The H&R TRAK+ adapter line is a trusted solution for enthusiasts seeking precise fitment when mixing wheel and hub bolt patterns. The DRA series is purpose-built for applications requiring 40–60mm of track widening and delivers a clean, factory-quality installation.
