H&R Wheel Adapter
H&R TRAK+® Wheel Adapters: German Engineering for the Perfect Fitment
When it comes to solving complex wheel fitment challenges without sacrificing safety or performance, few names carry the credibility of H&R Special Springs. Within their expansive wheel adapter lineup, H&R brings the same meticulous German engineering philosophy that earned them TÜV certification to every adapter they produce — making them a go-to choice for enthusiasts and track-day drivers alike.
The TRAK+® Adapter System Explained
H&R's TRAK+® Wheel Adapters are hubcentric spacers that allow you to change bolt patterns for different wheel fitments. This is the core function that sets them apart from generic spacers: rather than simply pushing the wheel outward, they actively translate one bolt pattern to another on the wheel side, opening the door to a far wider selection of compatible wheels.
TRAK+® Hub Adapters convert the vehicle hub to fit wheels of like bolt patterns but different hub center bores — allowing you to fit wheels from one car to another car and retain proper center bore alignment for the perfect fit. This hubcentric design is not a minor detail; it is what separates a safe, precision-fitted adapter from an afterthought. H&R TRAK+® Wheel Spacers are hubcentric and feature a full contact hub — just like the factory hub — for even load force distribution and lateral support.
Proprietary Materials & Construction
TRAK+® Wheel Spacers are manufactured from a special proprietary alloy specifically developed for H&R that is lighter and has a higher tensile strength than 6061-T6 billet aluminum. This custom alloy is not off-the-shelf material — it was engineered specifically for the demands of wheel adapter applications. The construction results in components up to 70% lighter than comparable steel products.
H&R wheel spacers are manufactured with the highest precision on state-of-the-art CNC machines. Whether in black or silver, spacers made from high-tensile aluminium alloy feature a special anodized coating that guarantees weatherproof corrosion protection and a long service life.
Key Features of H&R Wheel Adapters

- Proprietary Alloy: Made from a special proprietary alloy that is lighter and has a higher tensile strength than T6061 to T6 billet aluminum
- Bolt Pattern Conversion: Available in thicknesses ranging from 20mm to 25mm, H&R TRAK+® Wheel Adapters change a vehicle's bolt pattern so that wheels from a different vehicle make or model may be fitted.
- Wide Vehicle Coverage: Available for a wide range of automobiles, compatible with OEM and aftermarket suspension systems
- Quality Certified: 100% made in Germany under ISO 9001 Quality Assurance standards, meeting the stringent safety criteria of the German TÜV
- Hard Anodized Finish: Constructed from a proprietary aluminum/magnesium alloy created specifically for the H&R wheel spacer program, TRAK+® are extraordinarily strong and lightweight, and feature a hard anodized coating for surface durability.
Performance & Stance Benefits
The adapter system increases track width for a sportier look, improved stability, and enhanced handling, while ensuring safe and precise installation according to H&R's high quality standards. Whether you're fitting European aftermarket wheels to a different European platform or simply seeking a more aggressive stance, H&R's lineup covers an impressive range of bolt pattern conversion combinations — from common 5x100 to 5x112 swaps to more unique cross-platform applications.
