2002-2007 Subaru WRX/STI Subframe and Differential Lockdown Kit by Perrin Performance
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.
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.

Customer Reviews
I bought this kit mainly for the lock down bolts, i prefer to just replace the whole bushing instead of stacking bushings like the kit wants you to. But perrin/energy suspension are reputable brands so its fine to do just a personal preference! Like all my other reviews here are some tips and 1-10 levels!
1} use a thread restoration kit (thread chaser) try to reframe for using a tap. as taps are for cutting threads, chasers clean threads, and alot of oil. napa carries a whole kit for about $115, thats a tool i would make sure you own, i chase all my threads.
2} PLEASE USE JACK STANDS, A GOOD JACK, AND LEVEL SURFACE! you are going to have to drop/move the rear end components around so please be safe, and carful.
3}ANTI-SEIZE EVERYTHING! i cant stress anti-seize enough. if you plan on keeping the car for a long time, anti-seize everything that dont require lock tight!
4} always follow OE torque specs, you dont want your suspension components to tight they may bind, and definitely dont want them to loose!
Whole kit 8/10
skill level 4/10
special tools 1/10
I recommend using a thread chaser before installing the bolts. The bushing rings slide right in. Had to do a little prying on the rear diff, but all in all, it was simple. Definitely a cost-effective alternative to Group N or full poly bushings.
