    They're Great 3 years ago
    5out of 5stars
    It's taken me a while to review this item, since I wanted to see how they really improved the handling of the car. I have them set up at the neutral setting. The car does feel more planted when taking turns at high speeds, although there's still some bump steer, a lot less than with the stock bushings though. Yes, they are very noisy and when you hit a bump/pot hole/road reflectors... you will hear and feel it. I have 22mm front and rear sway set to the stiffest setting, Tein S. Tech Spring Kit and plenty of whiteline bushings. Install, it wasn't too hard as long as you have access to a press to remove the old bushings and install the new ones. Although the instruction don't explain how to properly line them up, if you have any suspension knowledge, you can figure it out. I did not have my car aligned after the install, but I hear that its a must. I just have not had any issues.

    • Q: 2011 WRX Fitment  FoolyCooli1 month ago

      It says it'll fit a 2011+ STI, but would it also fit a 2011 WRX? What's the difference between the two that keeps the 2011 WRX off the list of fitment?

        A:  Whiteline lists this as the 2011+ STI, but only 15+ WRX. I'm not sure why they made that designation, but that is what we were given by Whiteline.

    • Q: Caster & camber change  Nick Q.1 year ago

      These bushings add positive caster by locating the ball joint mount further forward, but by doing so does it also increase or decrease the track width? i ask because my tires are just barely touching my fenders at full compression and i am already running -2.6 degrees of camber so if this will push the ball joint farther outward i will need to run more negative camber for the same clearance which i do not wish to do.

        A:  I spoke with Whiteline, they said when adjusting caster, it will not impact track width in any way.

    • Q: How noisy  parf9092 years ago

      People say these bushings are "noisy" and "harsh riding". Do they actually spoil a daily driver car? How noisy and harsh are they? I want better steering and handling but not at the expense of something that takes the enjoyment out of driving the car.

        A:  The NVH of this going onto the car would not be horrible. It would improve the feeling of the car.

    • Q: Number of units inside  Paul3 years ago

      Hi, just wonder, does it comes with 2 units in the kit?
    • Q: Difference  jomartes3 years ago

      What's the difference between this one and the old one (WHI KCA425M)?
      • 0 of 0 people found the following answer helpful

        A:  It's looking like they updated the design just slightly for an easier install and a longer durability.
