PERRIN Rear Subframe Lockdown Kit for 2015-2026 Subaru WRX/STI & 2022-2026 BRZ (PSP-SUS-531BK)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2026 Subaru WRX, 2015-2021 WRX STI, and 2022-2026 Subaru BRZ models.
The PERRIN Rear Subframe Lockdown Kit (PSP-SUS-531BK) is engineered to eliminate the compliance and "slop" inherent in the factory rubber subframe bushings. By solidifying the connection between the rear subframe and the vehicle chassis, this kit ensures that suspension geometry remains stable under extreme loads, providing more predictable handling and sharper turn-in response.
Removing this unwanted movement is critical for performance driving; it prevents the subframe from shifting during high-G cornering or hard launches, which directly improves power delivery and chassis feedback. This bolt-on solution replaces or reinforces factory mounting points to create a more connected driving experience without the need for a full subframe removal.
- Reduces subframe and drivetrain movement during acceleration and braking
- Enhances throttle response by minimizing energy loss through bushing deflection
- Provides a more rigid chassis feel for track and spirited street use
- Engineered for a precise fit with included high-grade hardware
- Manufacturer Part Number: PSP-SUS-531BK
