SPL Parts Solid Subframe Bushings
2013–2020 Subaru BRZ / 2017–2020 Toyota 86 / 2022+ Toyota GR86
SPL SSB FRS
Overview:
The SPL Parts Solid Subframe Bushings are precision-engineered upgrades designed to replace the factory rubber bushings on the Subaru BRZ, Toyota 86, and Toyota GR86 models. These solid aluminum bushings eliminate the unwanted flex and free play found in stock subframe mounts, providing a more direct connection between the subframe and chassis. This upgrade is ideal for enthusiasts seeking improved suspension precision, reduced wheel hop, and enhanced drivetrain response under torque and suspension loads.
By stabilizing the subframe, these bushings help maintain optimal suspension geometry during aggressive driving, track days, or spirited street use. The included slide-in shim system allows for fine-tuning of the subframe height, enabling drivers to adjust roll center and anti-squat characteristics to suit their specific setup and driving style.
Key Features:
Engineered for performance and adjustability, the SPL Parts Solid Subframe Bushings offer the following key benefits:
- Replaces soft factory rubber bushings with rigid billet 6061 aluminum for zero subframe movement
- Eliminates subframe “bounce” under drivetrain torque and suspension load, reducing wheel hop
- Slide-in shim system allows precise adjustment of subframe height to tune roll center and anti-squat
- Raising the subframe compensates for lowered ride height by improving roll center at the expense of increased anti-squat
- Lowering the subframe reduces anti-squat for improved traction, with a trade-off in roll center position
- Includes optional rubber isolation washers to minimize noise and vibration transfer to the chassis
- Now compliant with Formula Drift regulations, allowing OEM height setups while remaining legal
- Complete kit designed specifically for one vehicle, ensuring proper fitment and ease of installation
- Made in the USA with high-quality CNC machining for consistent precision and durability
Construction & Design:
The SPL Parts Solid Subframe Bushings are crafted from billet 6061 aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. CNC machining ensures tight tolerances and a perfect fit, eliminating any slop between the subframe and chassis. The design incorporates a slide-in shim system that provides adjustability without compromising structural integrity.
Additionally, the kit includes optional rubber isolation washers that can be installed to reduce noise and harshness transmitted from the subframe to the vehicle’s cabin, offering a balance between performance and comfort. This thoughtful design approach makes the bushings suitable for both street and track applications.
Installation & Fitment:
Installation of the SPL Parts Solid Subframe Bushings requires removal of the factory rubber bushings and replacement with the solid aluminum units. The process is straightforward for experienced enthusiasts or professional installers familiar with suspension components on the Subaru BRZ, Toyota 86, and Toyota GR86 platforms. No permanent modifications to the vehicle are necessary, and the included shim system allows for quick adjustments to subframe height during installation.
This kit fits the following vehicles:
- Subaru BRZ model years 2013 through 2020
- Toyota 86 model years 2017 through 2020
- Toyota GR86 model years 2022 and newer
What's Included:
- Billet 6061 aluminum solid subframe bushings (complete set for one vehicle)
- Slide-in shim system for adjustable subframe height
- Optional rubber isolation washers to reduce noise and vibration
- Installation instructions for proper fitment and adjustment
Ideal For:
This upgrade is perfect for Subaru BRZ, Toyota 86, and Toyota GR86 owners who demand sharper handling, improved suspension response, and reduced drivetrain-induced wheel hop. It is especially beneficial for track enthusiasts, autocross competitors, and anyone who has lowered their vehicle and wants to fine-tune suspension geometry for optimal performance. Drivers seeking a more connected and predictable chassis feel will appreciate the precision and adjustability offered by these solid subframe bushings.
