Reinforce your rear end with confidence.
This Polyurethane Rear Member Collar Set is engineered to reduce unwanted movement in the rear subframe of your Toyota 86 or Subaru BRZ (ZN6/ZC6).
By tightening the connection between the subframe and chassis, these collars improve rear-end stability, traction, and suspension response—essential for high-performance driving, spirited street use, track days, or drifting.
Whether you’re chasing lap times, sliding through corners, or enjoying precise handling on the street, this rear member collar set offers the support your suspension needs—without the harshness of solid metal inserts.
