SPF4112-90K
Overview:
The Superpro Rear Differential-to-Subframe Mount Bushing Set is a direct replacement for the forward differential mount bushings, commonly referred to as the pinion mount bushings, on the Subaru BRZ, Toyota 86, and Toyota GR86 models within the specified year ranges. Designed for enthusiasts and daily drivers alike, this bushing set addresses the common issue of premature wear found in the original equipment manufacturer (OEM) rubber bushings. Over time, the soft rubber OEM bushings degrade, leading to increased differential movement, which negatively impacts vehicle responsiveness and driving precision.
By upgrading to Superpro’s high-performance bushings, drivers can expect improved differential stability under load, enhanced throttle response, and a more connected driving experience without sacrificing cabin comfort. These bushings maintain OEM levels of noise, vibration, and harshness (NVH) isolation, ensuring that the ride quality remains smooth and refined while delivering superior durability and performance.
Key Features:
Superpro’s Rear Differential-to-Subframe Mount Bushing Set offers a range of benefits engineered to enhance your vehicle’s drivetrain performance and longevity:
- Replaces soft OEM rubber bushings prone to rapid wear and degradation
- Reduces unwanted rear differential movement under acceleration and deceleration
- Improves throttle response and steering precision by stabilizing the differential
- Maintains factory-level noise, vibration, and harshness isolation for cabin comfort
- Constructed from durable polyurethane materials for extended service life
- Engineered to withstand aggressive driving and track conditions without compromising comfort
- Precision fitment ensures easy installation without modifications
- Compatible with Subaru BRZ (2013–2024), Toyota 86 (2017–2020), and Toyota GR86 (2022–2023)
Construction & Design:
Superpro utilizes advanced polyurethane compounds that outperform traditional rubber in both durability and performance. These bushings are engineered to resist the common issues of softening and degradation that affect OEM rubber components. The material maintains its stiffness and shape under a wide range of temperatures and driving conditions, ensuring consistent differential positioning and improved drivetrain feedback throughout the life of the product.
The design focuses on replicating the OEM bushing’s noise and vibration isolation characteristics while providing enhanced mechanical properties. This balance allows for a more precise drivetrain without introducing unwanted harshness or noise into the cabin, preserving the vehicle’s factory comfort standards.
Installation & Fitment:
The Superpro Rear Differential-to-Subframe Mount Bushing Set is designed for a straightforward, bolt-in installation using existing mounting hardware. No special tools or modifications are required, making it an ideal upgrade for both professional installers and experienced enthusiasts. Proper installation ensures the differential is securely located, reducing slop and improving overall vehicle dynamics.
This bushing set is specifically engineered to fit the Subaru BRZ models from 2013 through 2024, Toyota 86 models from 2017 through 2020, and Toyota GR86 models from 2022 through 2023, guaranteeing precise compatibility and optimal performance.
What's Included:
- Set of polyurethane rear differential-to-subframe mount bushings (pinion mount bushings)
- Installation instructions
Ideal For:
This bushing set is perfect for Subaru BRZ, Toyota 86, and Toyota GR86 owners seeking to restore or enhance their vehicle’s rear differential stability. It is especially beneficial for drivers who experience sloppy throttle response, excessive drivetrain movement, or noise and vibration related to worn OEM bushings. Whether you are a spirited street driver, weekend track enthusiast, or daily commuter wanting improved drivetrain precision without sacrificing comfort, this upgrade delivers reliable performance and longevity.
