Perrin 08-10 STi/WRX / 08-09 Impreza 2.5 Rear Differential Lockdown System

*SHIFTER BUSHINGS* *Eliminate the Sloppy Feel* PERRIN bushings eliminate the sloppy feeling during quick gear changes, giving the driver a more precise feel when shifting. Especially that crucial 2nd-3rd shift. See the Shifter Bushing at work HERE. *Stiff 88a Durometer Bushing* PERRIN Shifter bushings are a hard polyurethane bushing which eliminates slop but allows natural drivetrain movement. Simply replaces the OEM rubber shifter bushings with an easy install using simple hand tools. *SUBFRAME LOCKDOWN SYSTEM* Add drive train rigidity and precision to throttle input to your Subaru with our PERRIN Performance Diff Lock Down System. *Differential Lockdown* The PERRIN rear diff lock down (DLS) consists of 4 urethane bushings that lock the differential by stiffening the front and rear mounts for zero movement under extreme conditions such as drag racing and road racing. This DLS removes the twisting movement from the rear differential which can cause a “squishy” or spongy feeling at the point of initial acceleration. *Subframe Lockdown* The subframe lockdown kit includes 2 urethane bushings, two metal sleeve washers and 2 bolts. They work together to solidify and lock the rear subframe in place, eliminating all driveline slop and that annoying thud from first to second gear. *DIFFERENTIAL LOCKDOWN SYSTEM* Add drivetrain rigidity and precision to throttle input to your Subaru with our PERRIN Performance Diff Lockout Kit. PERRIN Differential Lockdown kit consists of 2 aluminum plates and 4 urethane bushings to completely remove any and all movement from the rear differential under all conditions. From performance street driving, to road racing, drifting or drag racing this will handle and improve it all! Under these conditions the drivetrain (diff included) will twist and move causing a “squishy” or spongy feel at the point of initial acceleration. The PERRIN rear diff lock down (DLS) locks the differential down for zero movement.
