PRECISE REAR-END CONTROL – ELIMINATING VAGUE MOVEMENT FOR PREDICTABLE HANDLING.

The Rear Member Collar is a chassis enhancement component engineered specifically for the Toyota 86 and Subaru BRZ. By converting the rear member mounting to a semi-rigid configuration, this collar addresses one of the platform’s inherent weaknesses—imprecise rear-end movement—resulting in sharper, more predictable handling characteristics.

Product Highlights

🔧 SEMI-RIGID REAR MEMBER CONVERSION
Transforms the lethargic factory rear member mounts into a more responsive semi-rigid setup. The collar inserts while retaining the original rubber components, providing increased rigidity where it matters most for chassis response.

🎯 ELIMINATES VAGUE REAR-END MOVEMENT
Directly addresses the 86/BRZ’s notorious rear-end ambiguity—the loose, imprecise sensation that undermines driver confidence. This upgrade provides tangible improvement in rear chassis stability and predictability.

⚖️ OPTIMAL BALANCE OF SPORTINESS AND COMFORT
Unlike full rigid mounting that introduces significant noise and vibration, this intelligent design sandwiches the factory rubber. Unwanted noise and vibration are minimized while achieving an appropriately sporty feel suitable for both track and street driving.

🔇 NOISE AND VIBRATION SUPPRESSED
The retention of factory rubber elements ensures that the common NVH penalties associated with rigid chassis mounting are kept to an absolute minimum, preserving daily driving refinement.
