Product Fitment:
2014-2021 Subaru WRX
Whiteline’s comprehensive performance kit is designed to enhance drivetrain responsiveness, shift feel, and power delivery for Subaru vehicles. The kit includes a Billet 6061-T6 aluminium pitch stop mount that replaces the soft, OEM plastic and rubber design to reduce engine and drivetrain movement, resulting in sharper throttle response. The Positive Shift Kit inserts into the factory gearbox mount to firm up shift feel and reduce slop. Differential insert bushings improve gear shift precision and power transfer by maintaining pinion angles and reducing torque loss. The rear crossmember insert bushings reduce excessive compliance and misalignment for improved rear-end stability during cornering. Finally, the shifter bushing kit eliminates the soft OEM feel, providing precise, clean gear shifts with reduced risk of missed shifts. Designed for easy installation and ideal for DIY enthusiasts, this kit delivers significant performance gains without the need for full bushing replacements.
