H&R 5055665571 TRAK+ Hubcentric Wheel Adapter 5/112 57.1 CB for Audi/VW Wheels (Pair)

The H&R TRAK+ Wheel Adapter (MPN 5055665571) is a precision-engineered, hubcentric bolt pattern adapter designed to allow Audi/VW wheels with a 5/112 bolt pattern and 57.1mm center bore to be fitted to vehicles with a different hub configuration. Sold as a pair, these adapters are part of H&R's renowned TRAK+ product family and are engineered in Germany to exacting quality standards.

What Are TRAK+ Wheel Adapters?

Unlike standard wheel spacers, TRAK+ Wheel Adapters feature a different bolt pattern on the wheel-facing side, enabling the fitment of wheels that would not otherwise be compatible with your vehicle's hub. The hubcentric design ensures the adapter seats flush against the factory hub—just like an OEM wheel—for proper load distribution and lateral support.

Key Features:

• Hubcentric design with full-contact hub interface for even load force distribution and lateral support
• Adapts to Audi/VW wheel fitment — 5/112 bolt pattern, 57.1mm center bore
• Proprietary aluminum alloy construction — higher tensile strength than standard 6061-T6 billet aluminum, yet significantly lighter than steel
• Hard anodized finish for corrosion resistance and long-term durability
• Widens vehicle track width — moves wheels outward for improved stance and flush fender fitment
• Improves handling — wider track lowers roll center and increases lateral stability
• Sold as a pair

Wheel Bolt Guidelines (When Applicable):

If your application requires new or longer wheel bolts, observe the following:

• New bolts must be longer than the originals by the width of the adapter
• Bolt head style must match the original — taper 60°, round head, or flat head as applicable
• Minimum thread engagement requirements by thread pitch:
  • M12 × 1.25 — minimum 8.0 turns (~10mm load-bearing shaft)
  • M12 × 1.50 — minimum 6.5 turns (~10mm load-bearing shaft)
  • M12 × 1.75 — minimum 6.5 turns (~12mm load-bearing shaft)
  • M14 × 1.25 — minimum 9.0 turns (~12mm load-bearing shaft)
  • M14 × 1.50 — minimum 7.5 turns (~12mm load-bearing shaft)
• After installation, rotate the wheel by hand and verify it clears all brake system components including ABS sensors

H&R TRAK+ adapters are manufactured in Germany and are a trusted solution for enthusiasts seeking improved fitment, optimized stance, and enhanced handling performance.
