H&R 50625601 TRAK+ Hubcentric Wheel Adapters for Audi/VW 5/100 - 57.1 CB (Pair)

The H&R TRAK+ Wheel Adapters (MPN: 50625601) are hubcentric bolt-pattern conversion spacers designed to allow wheels with a 5/100 bolt pattern and 57.1mm center bore to be fitted to a vehicle with a different factory bolt pattern. Sold as a pair, these adapters are engineered in Germany to H&R's exacting quality standards and are built to deliver both improved stance and reliable, long-term performance.

What They Do

Unlike a standard wheel spacer that simply pushes your wheels outward, TRAK+ Wheel Adapters feature a different bolt pattern on the wheel-facing side of the adapter, allowing you to mount Audi/VW 5/100 pattern wheels onto a vehicle with a non-matching factory bolt pattern. The hubcentric design ensures the adapter seats precisely against the vehicle hub — just like the OEM hub — for balanced load distribution and lateral support.

Key Features:

• Hubcentric design with full contact hub face for even load force distribution and lateral support
• Proprietary aluminum/magnesium alloy construction — lighter and stronger in tensile strength than standard 6061-T6 billet aluminum
• Hard anodized finish for a tough, corrosion-resistant surface
• Bolt pattern conversion — vehicle side accepts the factory hub; wheel side is configured for 5/100 - 57.1 CB Audi/VW wheels
• Sold as a pair (two adapters included)
• Compatible with both street driving and performance track use

Wheel Bolt Guidelines

When sourcing wheel bolts for use with these adapters, the replacement bolts must be longer than the originals by the thickness of the adapter used. The bolt head style must match the existing bolts exactly. Use the following end-digit reference when ordering H&R wheel bolts:

• 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 OEM wheels M14×1.5 — End digit 06

Minimum Thread Engagement Safety Reference:

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

After installation, always rotate the wheel by hand to confirm full clearance from brake components and ABS sensors. The wheel must spin freely with no contact inside the hub.
