H&R 40625640 TRAK+ Wheel Adapters 5/100 to 5/112 Audi/VW Hubcentric (Pair)

The H&R TRAK+ Wheel Adapters (Part #40625640) allow you to fit wheels with a different bolt pattern to your Audi or VW vehicle. Designed for vehicles with a 5/100 bolt pattern and 57.1mm center bore, these hubcentric adapters change the wheel-side bolt pattern so that non-standard wheels can be properly and safely mounted. Sold as a pair.

Like H&R's TRAK+ DRM Series Wheel Spacers, these adapters are hubcentric — they seat precisely on the vehicle hub just as a standard spacer would, then present a different bolt pattern on the wheel-facing side. This ensures a secure, centered fit with no vibration or hub stress. Available in thicknesses ranging from 20mm to 25mm, they also push the wheel outward to improve stance and increase track width.

Key Features:

• Hubcentric design — seats directly on the factory hub for precise fitment and zero vibration
• Adapts 5/100 (57.1mm CB) Audi/VW bolt pattern to accept wheels with a different bolt pattern
• Available in 20mm–25mm thickness for track widening and improved stance
• Proprietary aluminum/magnesium alloy construction — up to 70% lighter than comparable steel spacers
• Hard anodized finish for long-term durability and corrosion resistance
• Increases track width for improved lateral stability, lowered roll center, and enhanced handling
• Suitable for winter use with snow tire and wheel setups
• Sold as a pair (two adapters)

Wheel Bolt Guidelines (when ordering replacement bolts):

• New bolts must be longer than original bolts by the thickness of the spacer used
• Bolt head style must match existing bolts — taper 60° (end digit 01), round head M12/d24mm or M14/d28mm (end digit 02), round head M12/d26mm OE VAG wheels (end digit 03), or flat head Porsche OE M14×1.5 (end digit 06)

Minimum Wheel Bolt Engagement (safety reference):

• 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, rotate the wheel by hand to verify clearance inside the hub. Ensure wheel bolts do not contact ABS sensors or any part of the brake system. Note that clearance tolerances on some vehicles can be as tight as 2mm (e.g., rear axle on Mercedes models).
