H&R 40655662 TRAK+ Wheel Adapter Set 5/112 57.1CB to 5/112 66.2CB 40mm Pair

The H&R TRAK+ 40655662 is a hubcentric wheel adapter set designed to adapt Audi and Volkswagen wheels with a 5/112 bolt pattern and 57.1mm center bore to a different hub center bore configuration. Sold as a pair, these 40mm adapters allow wheels with a non-matching center bore to seat properly on the hub, eliminating vibration and ensuring precise wheel alignment.

How TRAK+ Wheel Adapters Work

Unlike standard spacers, TRAK+ Wheel Adapters feature a hubcentric design on both the vehicle side and the wheel side. The adapter bolts securely to the vehicle hub and provides a correctly sized center bore and bolt pattern on the outboard face, enabling fitment of wheels that would otherwise be incompatible with the factory hub specification.

Key Features:

• Hubcentric design — full contact hub interface for even load distribution and lateral support
• Proprietary aluminum/magnesium alloy — up to 70% lighter than a comparable steel product, with higher tensile strength than standard 6061-T6 billet aluminum
• Hard anodized finish — tough, durable surface treatment for long-term corrosion resistance
• Engineered and manufactured in Germany to H&R's strict quality standards
• 40mm thickness — widens track for improved stance and handling balance
• Sold as a pair (two adapters included)
• Compatible with 5/112 bolt pattern Audi and Volkswagen applications with 57.1mm center bore hubs

Wheel Bolt Guidelines

This adapter requires appropriate wheel bolts for safe installation. New bolts must be longer than the originals by the width of the adapter (40mm). The bolt head style must match your existing wheel bolts exactly. Minimum thread engagement requirements must be met — refer to your vehicle's service specifications and verify clearance with the brake system (including ABS sensors) before use. Rotate the wheel by hand to confirm free rotation after installation.

Minimum load-bearing shaft engagement by thread pitch:

• M12 x 1.25 — 8.0 turns (approx. 10mm engagement)
• M12 x 1.50 — 6.5 turns (approx. 10mm engagement)
• M12 x 1.75 — 6.5 turns (approx. 12mm engagement)
• M14 x 1.25 — 9.0 turns (approx. 12mm engagement)
• M14 x 1.50 — 7.5 turns (approx. 12mm engagement)

H&R TRAK+ adapters are a trusted solution for enthusiasts seeking to run Audi/VW bolt pattern wheels with a different center bore — combining German engineering, premium materials, and a precise hubcentric fit for both street and track use.
