Eliminate unwanted subframe movement and fine-tune rear suspension geometry with the SPL Solid Subframe Bushing Kit for the BRZ, FR-S, and GT86. These CNC-machined aluminum bushings replace the soft factory rubber mounts to drastically improve chassis control, throttle response, and overall handling performance.

The kit includes shims to adjust rear anti-squat and correct roll center for lowered vehicles, making it ideal for track, drift, or aggressive street setups.

Features

Eliminates Subframe Deflection
Factory rubber bushings allow excessive subframe movement under braking, acceleration, and cornering. This leads to inconsistent handling, poor throttle response, and wheel hop. SPL’s solid aluminum bushings remove this deflection completely, locking the subframe securely to the chassis.

Adjustable Anti-Squat Geometry
Includes 0.25″ and 0.33″ shims to modify the subframe’s installed angle. Adjusting anti-squat helps manage weight transfer under acceleration and can improve traction, suspension consistency, and aerodynamic efficiency.

Roll Center Correction
Lowered vehicles can experience unwanted roll geometry changes. This kit provides correction to bring the rear roll center back into alignment, reducing excessive body roll and maintaining suspension effectiveness.

Rules Compliant
The default install orientation retains OEM subframe angle, making it compliant with regulations from organizations such as Formula D.

Benefits:

• Adjustable anti-squat and roll center correction

• Significantly improves suspension response and stability

• Reduces or eliminates wheel hop

• Increases drivetrain and throttle response precision

• Never needs replacement like rubber bushings

• Lightweight: 3.91 lbs (1.77 kg) installed

Construction and Materials

• CNC-Machined 6061-T6 Aluminum Bushings and Spacers

• Precision Rubber Isolators (minimize NVH while maintaining stiffness)

• Complete hardware included

Solid subframe bushings will increase NVH compared to OEM rubber. More road and drivetrain noise may be transmitted into the cabin, especially when paired with other solid-mounted components. However, reduced drivetrain slop improves responsiveness during throttle and clutch inputs. Harshness over bumps may also increase slightly, but many drivers consider the trade-off worthwhile for the performance gain.
