SuperPro Rear Subframe Insert Bushing Kit – 2013–2016 Scion FR-S / Subaru BRZ / Toyota 86 – SPF3907K

Reduce unwanted rear-subframe movement and improve chassis response with the SuperPro SPF3907K rear subframe insert bushing kit.

Designed to work with the vehicle’s existing rear subframe mounts, these polyurethane inserts fill the open spaces in the factory rubber bushings. Limiting excess subframe movement can provide more direct handling, improved rear suspension response and a more connected feel during acceleration, braking and cornering.

Because this is an insert-style kit, the original rear subframe bushings remain installed. The design offers a practical suspension upgrade without requiring complete removal and replacement of the factory subframe mounts.
