H&R 505655714 TRAK+ 25mm Hubcentric Wheel Adapter 5/114.3 to 5/112 Pair

The H&R TRAK+ 505655714 is a 25mm hubcentric wheel adapter that converts a 5/114.3 bolt pattern (67.1mm center bore, M12x1.5 thread) hub to accept wheels with a 5/112 bolt pattern (57.1mm center bore, M14x1.5 thread). Sold as a pair, these adapters are ideal for fitting Audi, Volkswagen, or Mercedes-Benz style 5/112 wheels onto vehicles with the common Kia, Hyundai, Mazda, and Mitsubishi 5/114.3 bolt pattern.

Like all H&R TRAK+ adapters, the 505655714 bolts to the vehicle hub just as a standard wheel spacer would, but presents a completely different bolt pattern on the outboard face — enabling non-stock wheel fitment without sacrificing the precision of a hubcentric interface. Each adapter features a full-contact hub surface that mirrors the factory hub geometry for even load distribution and lateral support.

Key Features:

• 25mm thickness per side — 50mm total track widening per axle
• Vehicle side: 5/114.3 bolt pattern — 67.1mm center bore — M12x1.5 thread
• Wheel side: 5/112 bolt pattern — 57.1mm center bore — M14x1.5 thread
• Hubcentric design with full-contact hub surface for even load force distribution and lateral support
• Manufactured from a proprietary alloy with higher tensile strength than 6061-T6 billet aluminum
• Hard anodized finish for long-lasting durability
• Made in Germany to H&R's exacting quality standards
• Sold as a pair (2 adapters)

The DRA-series design used in these adapters bolts directly to the hub using supplied attachment hardware and provides new threaded holes on the wheel side — no modification to existing studs required. This makes installation straightforward and repeatable.

Wheel Bolt Safety 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 (25mm). The bolt head style must match the wheel's seating surface exactly:

• 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 engagement (load-bearing shaft length) requirements by thread specification:

• M12×1.25 — 8.0 turns — approx. 10mm engagement
• M12×1.50 — 6.5 turns — approx. 10mm engagement
• M12×1.75 — 6.5 turns — approx. 12mm engagement
• M14×1.25 — 9.0 turns — approx. 12mm engagement
• M14×1.50 — 7.5 turns — approx. 12mm engagement
• 1/2″ UNF — 8.0 turns — approx. 11mm engagement

After installation, always rotate the wheel by hand and verify adequate clearance from the brake system, ABS sensors, and surrounding components before driving.
