Zestek Steering Wheel Boss Kit – Toyota 86/Subaru BRZ/Impreza
Fit a quality aftermarket steering wheel to your Toyota 86, Subaru BRZ or Subaru Impreza with confidence. This Zestek boss kit adapts the factory splined steering column to the common 6×70 PCD pattern used by many performance wheels (Momo/Sparco style). It gives a centred, solid connection for better feel and control.
Why choose this boss kit
- Adapts the OEM column to the standard 6×70 PCD – 6 bolts on a 70 mm circle – for wide wheel compatibility.
- Accurate spline fit for a secure, play-free connection.
- Improves driving position and feedback when paired with a good wheel.
- Durable build for daily use and spirited driving.
- Simple, bolt-on installation with basic tools.
Fitment
Designed for popular Toyota 86/GT86, Subaru BRZ, and select Subaru Impreza models. Fitment can vary by year and trim. Please use our vehicle lookup to confirm your car, or check the Vehicle Fitment tab for full details before ordering.
Installation overview
- Disconnect the battery and wait a few minutes before starting.
- Remove the factory airbag and steering wheel as per the workshop manual.
- Slide the Zestek boss onto the OEM splined column and seat it fully.
- Tighten the centre fixing to the torque specified by the manufacturer.
- Bolt your 6×70 PCD wheel to the boss and align straight ahead.
- Check for warning lights and proper steering operation.
Important notes
This boss kit deletes the factory airbag. This can trigger warning lights and may affect road legality and insurance. Resistors or ECU coding may be needed to clear warnings. Multifunction buttons and heating on the original wheel will not carry over to most aftermarket wheels. If unsure, consult a qualified technician.
