STG GR Yaris 21.5mm Bolt-On Wheel Spacers — Set of 4
The most popular upgrade among GR Yaris owners — and for good reason. Our 21.5mm bolt-on aluminium wheel spacers are engineered specifically for the Toyota GR Yaris, filling the arches cleanly, widening the track for improved stability, and giving the stance that the factory setup never quite delivered.
Unlike slip-on spacers, our bolt-on design uses extended wheel bolts that thread directly into the hub — making them the only type approved for road and track use. These are the spacers fitted to our own demo car, tested at events and on the road before ever going on sale.
Key features

Fitment
Compatible with: Toyota GR Yaris Gen 1 (2020–2024) and GR Yaris Gen 2 (2024–present). Suitable for use with OEM wheels and most aftermarket 18" fitments. If running larger-than-standard tyres or aftermarket arches, contact us before ordering.
Why 21.5mm?
We arrived at 21.5mm after extensive testing across different wheel and tyre combinations on our own GR Yaris fleet. It's the sweet spot: enough to transform the stance and widen the track by 43mm total (front and rear), without rubbing on standard arches under full lock or compression.
With over 290 sets sold, these are by far the most popular single upgrade we offer — and the most common first modification GR Yaris owners make.
Supplied as a complete set of 4 with all fixing hardware. Available for immediate dispatch. If you have a fitment question, get in touch — we know this car inside out.
