H&R 807957401 TRAK+ Wheel Adapters Hubcentric 5/130 to 5/130 71.6CB (Pair)

The H&R TRAK+ Wheel Adapters (Part #807957401) are precision-engineered hubcentric adapters designed to adapt Porsche Cayenne wheels with a 5/130 bolt pattern and 71.6mm center bore. Sold as a pair, these adapters allow wheels with a different bolt pattern to be fitted to your vehicle while simultaneously widening the track for improved stance and handling dynamics.

Unlike basic spacers, TRAK+ Wheel Adapters feature a hubcentric design that seats directly onto the vehicle hub just like a standard wheel spacer — but with a different bolt pattern on the wheel-facing side. This allows non-standard bolt pattern wheels to be safely and securely mounted without compromising hub centering or structural integrity. Available in thicknesses ranging from 20mm to 25mm.

Key Features:

• Hubcentric design — fits to the vehicle hub for precise, vibration-free mounting
• Adapts 5/130 bolt pattern wheels (Porsche Cayenne) — 71.6mm center bore
• Made from a proprietary aluminum/magnesium alloy — up to 70% lighter than comparable steel products
• Hard anodized finish for maximum durability and corrosion resistance
• Maximizes vehicle track width for improved lateral stability and lowered roll center
• Excellent for winter use with dedicated snow tire and wheel packages
• Sold as a pair (two adapters)

Wheel Bolt Ordering Guidelines:

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

• New bolts must be longer than original bolts by the thickness of the adapter used
• Bolt head style must match existing bolts — reference end digit codes: 01 = Taper 60°, 02 = Round head M12/d24mm or M14/d28mm, 03 = Round head M12/d26mm (OE VAG wheels), 06 = Flat head for Porsche OE M14×1.5

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 turn the wheel by hand to verify clearance on the inside of the hub. Ensure wheel bolts do not contact any brake system components, including ABS sensors. Note that maximum tolerance on some vehicles (e.g., rear axle Mercedes-Benz) may be as little as 2mm.
