H&R 6055665571 TRAK+ Wheel Adapters 5/112 to 5/112 57.1mm Hub Audi VW (Pair)

The H&R TRAK+ Wheel Adapters (Part #6055665571) are a pair of hubcentric spacer-adapters designed for Audi and Volkswagen applications with a 5/112 bolt pattern and 57.1mm center bore. These adapters allow fitment of wheels with a different bolt pattern by changing the vehicle-side bolt pattern to a compatible wheel-side pattern, effectively expanding your wheel fitment options while also pushing the wheel outward for improved track width and stance.

Unlike simple flat spacers, H&R TRAK+ Wheel Adapters are hubcentric — they seat precisely on the vehicle hub, eliminating vibration and ensuring proper load distribution. Available in thicknesses ranging from 20mm to 25mm, they are constructed from a proprietary aluminum/magnesium alloy that is up to 70% lighter than a comparable steel product, then hard anodized for a durable, corrosion-resistant finish.

Key Features:

• Hubcentric design — fits precisely to the vehicle hub for vibration-free performance
• 5/112 bolt pattern with 57.1mm center bore — engineered for Audi and Volkswagen applications
• Sold as a pair — includes two (2) adapters
• Proprietary aluminum/magnesium alloy construction — up to 70% lighter than comparable steel
• Hard anodized finish — tough, durable, and corrosion resistant
• Maximizes vehicle track width for improved lateral stability and handling
• Lowers roll center for a more planted, confident driving feel
• Compatible with winter wheel and snow tire setups

Wheel Bolt Ordering Guidelines:

When selecting replacement wheel bolts for use with these adapters, follow these guidelines:

• New bolts must be longer than the originals by the width of the adapter used
• The bolt head style must match your existing bolts — verify taper or round head type before ordering
• Taper 60° seat — end digit 01
• Round head M12/d24mm or M14/d28mm — end digit 02
• Round head M12/d26mm (e.g., OE VAG wheels) — end digit 03
• Flat head for Porsche OE wheels M14×1.5 — end digit 06

Minimum Wheel Bolt Engagement (Safety Guidelines):

• M12×1.25 — 8.0 turns / ~10mm load-bearing shaft length
• M12×1.50 — 6.5 turns / ~10mm load-bearing shaft length
• M12×1.75 — 6.5 turns / ~12mm load-bearing shaft length
• M14×1.25 — 9.0 turns / ~12mm load-bearing shaft length
• M14×1.50 — 7.5 turns / ~12mm load-bearing shaft length
• 1/2" UNF — 8.0 turns / ~11mm load-bearing shaft length

After installation, always verify that wheel bolts do not contact any brake system components, including ABS sensors. Rotate the wheel by hand to confirm full clearance inside the hub. Note: Maximum tolerance on some vehicles (e.g., Mercedes rear axle) may be as little as 2mm.
