    PERRIN Subframe Lockdown Kit ( Part Number: PSP-SUS-525)
    It made a difference 2 months ago
    After installing the kit, it made the car feels more solid while driving around town. The only complain I have is the bolt, my mechanic has to shave off some part of it to fit in my Sti's subframe hole.. Other than that, a good upgrade.

    Installed with hell of a YouTube video. Seems to help take out the shake you feel from a stop to take off.

    does the job but not without concequence 4 years ago
    the bolts are great. they improve handling significantly making directional change more precise and the car more connected and less sloppy. the diff bushings on the other hand. i installed only the front ones when i did the bolts as thats all i had time for and they made the diff whine at highway speed cruising so loud i wanted to take them back out the next day. if i were to do it again id get the bolts by themselves. the bushings may hold the diff in place better but i dont feels its worth all the extra noise unless it was a race car or something. this is my daily however.

    Excellent 4 years ago
    I lifted my 2006 wrx wagon and with these I noticed a huge difference in the back end of the cars handling. Even though it was a Wagon and Lifted 1 it made a huge difference, best money ever spent. Love it.

    • Q: Sound  LuisF_WRX2 years ago

      I've read that after installing this kit there should be a sound in the rear diff that suppose to be normal. What of noise is this? a howl? rumble? knock?

        A:  We wouldn't be able to say if your car would make a noise with these bushings. But upgraded bushings tend to be more solid than OEM and will have more noise transfer throughout the vehicle.

    • Q: Figment with4EAt?  Jackstand Johnny3 years ago

      I have a 2002 WRX wagon with a 4EAt auto trans. Will this rear diff lockdown kit work with the 4EAT or is it just for the 5MT? Thanks in advance.
