H&R 50675662 TRAK+ Hubcentric Wheel Adapters for BMW 5x120 72.5CB (Pair)

The H&R TRAK+ Wheel Adapters (MPN: 50675662) are hubcentric wheel adapters designed to adapt BMW wheels with a 5x120 bolt pattern and 72.5mm center bore. Sold as a pair, these adapters allow you to fit wheels with a different bolt pattern to your vehicle — combining the functionality of a wheel spacer with the ability to change the bolt pattern on the wheel side. Available in thicknesses ranging from 20mm to 25mm.

Like H&R's TRAK+ DRM Series spacers, these adapters are hubcentric, meaning they seat precisely on the vehicle hub just as a standard wheel spacer would — eliminating vibration and ensuring a safe, secure fit. The wheel-side face of the adapter features a different bolt pattern, enabling non-standard bolt pattern wheel fitment with confidence.

Key Features:

• Hubcentric design — seats flush on the vehicle hub for vibration-free performance
• Bolt pattern adaptation — allows fitment of wheels with a different bolt pattern
• Made from a proprietary aluminum/magnesium alloy — up to 70% lighter than comparable steel products
• Hard anodized finish for long-lasting durability and corrosion resistance
• Maximizes vehicle track width for improved lateral stability and handling
• Lowers roll center for a more planted, performance-oriented stance
• Ideal for winter use with dedicated snow tire and wheel setups
• Sold as a pair (two adapters)

Wheel Bolt Guidelines (when ordering replacement bolts):

• New bolts must be longer than the originals by the thickness of the adapter used
• Bolt head style must match the existing bolts — verify taper (60°) or round/flat head type before ordering
• Taper 60° — 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 M14×1.5 — end digit 06

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 rotate the wheel by hand to confirm it spins freely and that bolts do not contact any brake components or ABS sensors. Note that clearance tolerances on some vehicles may be as little as 2mm.
