Zestek Steering Wheel Boss Kit – Toyota GR Yaris / GR Corolla
The Zestek Steering Wheel Boss Kit is designed to let you fit a Zestek Hub to your Toyota GR Yaris or GR Corolla in a clean, safe and reliable way.
What this boss kit does
This boss kit connects your car’s factory steering column to a zestek hub. It creates the correct spacing, angle and bolt pattern so the wheel fits securely and sits in the right position for driving.
Why it matters for your GR
- Keeps the wheel centred and at the proper distance for comfort and control
- Designed specifically for GR Yaris and GR Corolla fitment for a more precise installation
A dedicated boss kit is important because it matches the spline (the toothed shaft that the steering wheel mounts on) and geometry of your specific model. This helps maintain proper steering feel and reduces play in the wheel.
Compatibility and fitment
This boss kit is designed for the Toyota GR Yaris and GR Corolla platforms. It matches the factory steering column so you can install a compatible aftermarket wheel without needing custom machining or guesswork.
As with any interior or steering upgrade, always confirm fitment for your exact model, year and trim. Please use the vehicle lookup on the Progressive Parts website or check the “Vehicle Fitment” tab on this product page for full details.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
