ENHANCED TRACTION, ACCELERATION, AND CONTROL WITH MINIMAL NVH PENALTY.

The Diff Mount Collar is a performance-oriented upgrade designed for the Toyota 86 and Subaru BRZ. By converting the factory differential mount to a semi-rigid configuration, this collar eliminates the vague, sloppy feeling that compromises rear-end responsiveness—all while suppressing unpleasant vibrations and noise through intelligent use of the original rubber components.

Product Highlights

🔧 SEMI-RIGID CONVERSION WITHOUT HARSHNESS
Transforms the lethargic factory differential mount into a more responsive semi-rigid setup. By inserting the collar while retaining the original rubber mount, it provides increased rigidity where needed without transmitting excessive NVH (Noise, Vibration, Harshness) into the cabin.

⚡ RECOVERED TRACTION AND ACCELERATION RESPONSE
Eliminates the “dull” sensation caused by excessive diff movement under load. Drivers will experience more immediate power delivery, reduced wheel hop, and improved traction during hard acceleration—translating power to the pavement more effectively.

🎯 PRECISE CONTROL AND VEHICLE STABILITY
Enhanced differential mounting improves rear-end geometry control during cornering and throttle modulation. The result is more predictable handling, better mid-corner adjustability, and a greater sense of connection to the vehicle’s rear dynamics.

🔇 INTELLIGENT DESIGN SUPPRESSES UNWANTED NOISE
Unlike full solid mounts that introduce significant driveline noise and vibration, this collar sandwiches the factory rubber, preserving its inherent damping properties. Unpleasant noises and vibrations are kept to a minimum for comfortable daily driving.
