Perrin Performance Steering Rack Bushings Subaru WRX 2005-2014 / STI 2005-2021 | PSP-SUS-564

The Perrin Performance Steering Rack Bushings (PSP-SUS-564) are a direct-fit upgrade for the 2005–2014 Subaru WRX and 2005–2021 Subaru STI, engineered to eliminate the vague, imprecise steering feel caused by worn or soft OEM rubber bushings. Designed for performance-oriented drivers and motorsport enthusiasts, these polyurethane (PA) bushings reduce steering rack flex and improve steering response, giving you sharper, more connected feedback through every corner. Whether you're running spirited canyon roads or competitive track days, this is one of the best Subaru WRX/STI steering rack bushing upgrades available.

Key Features & Benefits

• Polyurethane (PA) Construction – Significantly stiffer than OEM rubber bushings, reducing steering rack movement and improving directional precision without sacrificing street drivability.
• Sharper Steering Response – Minimizes lateral rack deflection under hard cornering and braking, translating driver input more directly to the front wheels for a confident, connected feel.
• Reduced Steering Vagueness – Eliminates the "dead zone" or slop commonly associated with aging OEM rubber bushings, restoring or surpassing factory-fresh steering feel.
• Direct OEM Replacement – Engineered to fit exactly where the factory bushings live — no drilling, no modification, no fabrication required for a straightforward installation.
• Long-Term Durability – Polyurethane resists oil, grease, road grime, and environmental degradation far better than OEM rubber, ensuring a longer service life even under demanding conditions.
• Track & Street Proven – Developed and validated by Perrin Performance, a trusted name in the Subaru performance community for over 20 years, with products tested on some of the most demanding circuits in North America.
• Retains Rack Position – Helps keep the steering rack properly located in its subframe cradle under aggressive load, contributing to more consistent alignment geometry during hard driving.
