IKEYA FORMULA Rear Subframe Collars (Aluminum)

To suit Toyota ZN6 GT86 and Subaru ZC6 BRZ

Factory member bushes are designed to absorb vibration between the suspension subframe and body by flexing rubber. However, under increased traction from spirited driving or tuning, these bushes can twist excessively, causing suspension judder and reducing overall chassis performance.

This spacer kit converts the bush into a semi-rigid setup by sandwiching it from above and below with spacers, significantly improving chassis rigidity and maintaining proper suspension behavior under load. The result is sharper handling, better road feedback, and optimized suspension movement—ideal for sports driving.

Made from lightweight aluminum for maximum rigidity and easy to install without removing the subframe, making them a quick and effective upgrade.
