Cusco Rear Differential Rigid Mount Collar Front Side 2021+ Toyota GR Yaris 1.6L AWD - Blue

When you're pushing your 2021+ Toyota GR Yaris hard, especially during spirited driving or track use, you might notice some flex or movement in the rear differential. This Cusco Rear Differential Rigid Mount Collar is designed to address that by reinforcing the front side of the differential mount.

This collar is made from well-built aluminum and installs onto the front differential mount bracket. It effectively tightens up the connection between the differential and the chassis, reducing unwanted movement under load. This improved stability can lead to a more direct and predictable feel from the rear end, especially when accelerating out of corners or during hard braking. The blue anodized finish adds a nice touch under the car.

For installation, you'll typically need to remove the front differential mount bracket to slide this collar into place. It's a straightforward modification that can make a notable difference in how the rear of your GR Yaris handles when you're asking a lot of it.
