H&R 607957251 TRAK+ 30mm Wheel Adapter 5/130-71.6 CB to 5/120-72.5 CB (Pair)

The H&R TRAK+ 607957251 is a 30mm hubcentric wheel adapter that converts a 5x120 / 72.5mm center bore vehicle hub to accept 5x130 / 71.6mm center bore Porsche-pattern wheels. Sold as a pair, these adapters allow you to fit Porsche-bolt-pattern wheels onto vehicles with a 5x120 hub, while simultaneously widening the track for improved stance and handling dynamics.

H&R TRAK+ Wheel Adapters are engineered and manufactured in Germany to exacting tolerances. Like all TRAK+ spacers, they mount hubcentrically to the vehicle — matching the factory hub interface for even load distribution and full lateral support. The wheel side of the adapter features the alternate bolt pattern, enabling a clean, precise fit without compromise.

Key Features:

• Hubcentric design — full contact hub interface mirrors the factory hub for even load force distribution and lateral support
• 30mm thickness — widens track for improved stance and cornering stability
• Vehicle side: 5/120 bolt pattern, 72.5mm center bore
• Wheel side: 5/130 bolt pattern, 71.6mm center bore (Porsche-pattern wheels)
• Proprietary aluminum/magnesium alloy — higher tensile strength than 6061-T6 billet aluminum, up to 70% lighter than a comparable steel product
• Hard anodized finish — tough, corrosion-resistant surface treatment
• Sold as a pair (two adapters)

Wheel Bolt Guidelines:

When installing these adapters, replacement wheel bolts will be required. New bolts must be longer than the originals by the width of the spacer (30mm). The bolt head style must match the existing bolts exactly. Refer to the following end-digit codes when ordering replacement 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 OE wheels 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 on the inside of the hub. Bolts must not contact any brake system components, including ABS sensors. Note that clearance tolerances on some vehicles can be as tight as 2mm.
