Zestek Steering Wheel Boss Kit – BMW F/G Series
Fit an aftermarket steering wheel to your BMW with confidence. This Zestek boss kit adapts the factory steering column to the common 6×70 PCD pattern used by many performance wheels (Momo/Sparco style). It gives a solid, centred connection for better feel and control.
Why choose this boss kit
- Enables the use of popular aftermarket steering wheels on BMW F and G Series models.
- Accurate spline fit for a secure, play-free connection to the column.
- Standard 6×70 PCD mounting for wide wheel compatibility.
- Improves driving position and feedback when paired with a quality wheel.
- Durable construction to handle daily use and spirited driving.
Fitment
Designed for selected BMW F/G Series platforms, including many 1, 2, 3, 4 and 5 Series models, plus related variants. Fitment can vary by year and trim, so please use our vehicle lookup to confirm, or check the Vehicle Fitment tab for full details before ordering.
What to expect when installing
This is a bolt-on upgrade that replaces the factory steering wheel. You will remove the original wheel and airbag, fit the boss to the OEM splined column, then bolt your chosen wheel to the boss using the 6×70 PCD pattern.
Important: This boss kit deletes the factory airbag. This may trigger warning lights and can affect road legality and insurance. Additional resistors or ECU coding may be required to clear warnings. Multifunction controls and heating will not carry over to most aftermarket wheels. If in doubt, consult a qualified technician.
