H&R 506556011 TRAK+ Wheel Adapters 5/112 to 5/112 57.1mm Hub Audi VW (Pair)

The H&R TRAK+ Wheel Adapters (Part# 506556011) are hubcentric wheel adapters designed to adapt Audi and Volkswagen wheels with a 5/112 bolt pattern and 57.1mm center bore. Sold as a pair, these adapters allow fitment of wheels with a different bolt pattern while simultaneously widening the vehicle's track for improved stance and handling. They are an ideal solution for enthusiasts looking to run non-standard bolt pattern wheels on their Audi or VW platform.

Unlike simple spacers, TRAK+ Wheel Adapters are fully hubcentric — they seat precisely on the vehicle's hub just like a standard TRAK+ spacer, but feature a different bolt pattern on the wheel-facing side, enabling non-OEM wheel fitment without sacrificing hub centering accuracy or safety.

Key Features:

• Hubcentric design — fits precisely to the vehicle hub for vibration-free performance
• Bolt pattern adaptation — allows fitment of wheels with a different bolt pattern than the OEM hub
• Compatible with 5/112 – 57.1mm CB Audi and VW applications
• Sold as a pair (two adapters included)
• Constructed from a proprietary aluminum/magnesium alloy — up to 70% lighter than a comparable steel product
• Hard anodized finish for lasting durability and corrosion resistance
• Widens vehicle track width to improve lateral stability, lower roll center, and enhance overall handling
• Available in thicknesses ranging from 20mm to 25mm

Wheel Bolt Guidelines:

When fitting wheel adapters, replacement wheel bolts must be longer than the originals by the thickness of the adapter. The bolt head style must match the existing bolts precisely:

• 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 rotate the wheel by hand to verify full clearance from brake components, ABS sensors, and all hub hardware. Note that maximum tolerance on some vehicles (e.g., Mercedes rear axle) may be as little as 2mm.
