Bolts and subframe bushings worked fine. But the rear diff carrier support bushing inserts didn't help at all, the bushings were so shot. Had to replace the whole part, instead. Over-all, decent product, even though some parts are arguably useless. Installing the rear bushing inserts wasn't easy, either.

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.

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.

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_WRX7 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 Johnny8 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.
