H&R 509557160 TRAK+ Wheel Adapters 5/112 to 5/112 57.1mm Hub Centric Pair

The H&R TRAK+ Wheel Adapters (Part# 509557160) allow you to fit wheels with a different bolt pattern to your Audi or VW vehicle. Designed for vehicles with a 5/112 bolt pattern and 57.1mm center bore, these hubcentric adapters are sold as a pair and are available in thicknesses ranging from 20mm to 25mm.

Like H&R's TRAK+ DRM Series Wheel Spacers, these adapters mount hubcentrically to the vehicle hub — just as a standard TRAK+ Wheel Spacer would. The wheel-facing side of the adapter features a different bolt pattern, enabling non-standard bolt pattern wheel fitment without sacrificing hub centering precision.

Key Features:

• Hubcentric design — fits precisely to the vehicle hub for vibration-free performance
• Maximizes vehicle track width for improved appearance, lowered roll center, and increased lateral stability
• Manufactured from a proprietary aluminum/magnesium alloy — up to 70% lighter than a comparable steel product
• Hard anodized finish for long-lasting durability and corrosion resistance
• Suitable for winter use with dedicated snow tires and wheels
• Sold as a pair (2 adapters)

Wheel Bolt Selection Guidelines:

When ordering replacement or extended wheel bolts for use with these adapters, follow these specifications:

• New bolts must be longer than the originals by the thickness of the adapter used
• 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 Porsche OE wheels M14×1.5 — End digit 06

Minimum Wheel Bolt Engagement (Safety Guidelines):

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

After installation, rotate the wheel by hand to confirm clearance on the inside of the hub. Ensure wheel bolts do not contact or damage ABS sensors or any brake system components. Note that maximum clearance tolerance on some vehicles may be as little as 2mm (e.g., Mercedes rear axle).
