    Huge Improvement  7 years ago
    4out of 5stars

    My stock bushings were absolutely shot and my car would pull to the right at hard acceleration. I replaced my OEM bushings with these. Huge difference! My car is so much more stable. There is a noticeable difference in the corners as well! Only reason for 4/5 stars is for the NVH. The vibration noise was much louder than expected. Not enough to uninstall them, But enough to annoy my girlfriend.

    Nice product 7 years ago
    5out of 5stars

    I had these installed on my 07 STi along with the Whiteline rear diff bushings. All I can say is that there is ZERO clunk coming from the diff. I am not sure how much NHV the outrigger bushings are responsible for because I did the read diff bushings at the same time, but I can tell you I do get a good amount of noise from the rear at freeway speeds, but no noticable vibration. The only downside to this product is the noise, but if you can't sacrifice some noise for better performance, you probably shouldn't consider this upgrade.

    • Q: Stand alone?  Quenton942 years ago

      Could these stand alone or must they be reinstalled in the bracket? I have a torque solutions support bracket (see image) and am not able to squeeze the old bracket inbetween
      • 1 of 2 people found the following answer helpful

        A:  These bushings replace the stock bushings in the rear diff support outrigger position, we cannot confirm fitment with the Torque Solutions support bracket.

    • Q: a question about where these bushings go ?   Dj l.3 years ago

      so i am very confused for some reason on where these bushings go compared to where the whiteline Rear differential bushings go ? do these go into the bracket that hide in the subframe that connect to the diff ? or on the subframe itself ?

    • Q: install  BNBMotorsports5 years ago

      when you install these bushings do you still need the plate that goes in between the oem bushing and the chassis? or do these eliminate those now?
    • Q: How much louder are we talking about?  mrdr708275 years ago

      130K+ miles on my 04 WRX and I'm sure these are worn out by now. I would like to get some feeling back in the car since the rear has been a bit sloppy feeling. Koni struts are also worn out. Replacing those too under warranty. How much louder with these bushings be compared to stock rubber units being noiseless? Is it loud like an aftermarket exhaust or loud like a window air conditioner? Thanks, Mike

        A:  The sound level will not be drastic, and maybe not even noticeable to some people inside the vehicle. Generally and normal driving you wont notice much, and at more aggressive driving the drone of the exhaust cancels out most other noises.

    • Q: Different?  ShagginWagon4106 years ago

      these are different from the bushings that come in the perrin lockdown kit with the subframe bolts right?
      • 2 of 3 people found the following answer helpful

        A:  These bushings install in the same location as the Perrin lockdown kit, but they are mounted differently. You could use both together, but both would be overkill in my opinion.
