Function and Form’s 5×100 to 5×112 wheel adapter is the ideal solution for fitting 5×112 wheels onto vehicles equipped with a 5×100 bolt pattern. Built with precision and safety in mind, this hubcentric adapter allows you to expand your wheel options to include popular VW, Audi, and Mercedes-Benz wheels while preserving correct geometry, stability, and alignment.

Each 5×100 to 5×112 wheel adapter is CNC-machined from hot-forged aircraft-grade aluminum, offering a high strength-to-weight ratio and long-term durability under performance driving. The hubcentric design ensures the adapter centers perfectly on the vehicle hub, eliminating vibration and ensuring even load distribution for safer, smoother driving.

These adapters feature a center bore of 57.10 mm, making them a direct fit for select early Volkswagen and Audi models that came with 5×100 hubs. On the wheel side, the adapter steps out to a 5×112 pattern with a wheel bore that accepts standard German wheels.

The vehicle-side thread uses M14x1.50, matching factory thread pitch for most VW and Audi platforms. The wheel-side studs are pre-installed and use M12x1.50 thread pitch—compatible with most OEM and aftermarket 5×112 wheels from Audi, Mercedes-Benz, and Volkswagen.

These adapters are available in multiple thickness options, ranging from 15mm to 25mm, allowing you to address brake clearance issues, push wheels out for improved stance, or correct offset when switching to 5×112 wheels. They’re a great option for fitment correction while keeping things safe and structurally sound.

Each adapter includes functional touches like straight knurled edges for better grip during installation and removal, as well as integrated micro-channel grooves to prevent the adapter from sticking to the hub or wheel face over time due to heat, corrosion, or pressure.

The stealth Undercover Black finish blends in behind the wheel while offering additional protection from the elements. Each set is sold in pairs, giving you what you need for one axle—add a second set for a full 4-corner conversion.

If you’re converting to a 5×112 wheel setup and want a clean, engineered solution, the Function and Form 5×100 to 5×112 wheel adapter is the safe, reliable answer.
