Perrin Subframe Lockdown For Differentials - Kit

02-07 Impreza / 02-07 WRX / 04-07 STI

Description:
Add drive train rigidity and precision to throttle input to your Subaru with our PERRIN Performance Diff Lock Down System. This kit consists of (2) kits in one, the DLS and SLS. The DLS (differential lock down system) consists of 6 urethane bushings to lock down the rear differential support beams. This helps remove movement from the rear differential under extreme conditions such as drag racing and road racing. Under these conditions the drive train (diff included) will twist and move around before it starts to turn the wheels causing a "squishy" or spongy feel at the point of initial acceleration. The PERRIN rear diff lock down (DLS) locks the differential by stiffening up the front and rear mounts for zero movement so when you push on the gas, the car goes with no delay.

Also included in the kit is the PERRIN (SLS)Subrame lockdown kit. The rear subframe on the 02-07 Impreze/STI/WRX is mounted to the chassis with rubber bushings. Under extreme conditions like road racing where high cornering forces are seen, the subframe moves around causing a loose feeling in the car. This also can cause the alignment of the wheels to change, also causing a feeling of looseness.

As you can see both the SLS and DLS goes hand and hand and can make a noticeable difference on your 02-07 STI/WRX/Impreza.
