Bushings Upgrade For WRX
Chris adjusts the rear toe by turning the adjusters on the Whiteline links. The camber is also adjusted here.
Chris then adjusts the front toe.
Next, Chris measures and adjusts the front and rear camber.
The front camber is adjusted at the camber plate and the rear, via the Whiteline lateral links. Once the camber is set, the toe settings are touched up as the camber has some effect on them and vice versa. We set the front camber at negative 3 degrees with 1/8″ toe out. The caster ended up being 4 degrees positive up from the stock 3.5 degrees.   For the rear, we had the camber set at 1.5 degrees negative with zero rear toe.   This is a good aggressive but still streetable alignment setting for an AWD car.
Finally, Chris adjusted the sway bar end link lengths to get rid of every bit of bind in the sway bars.

With our WRX’s suspension all setup and ready to go, we went out on a test drive. Boy, were we impressed! We were worried about all the hard Whiteline bushings increasing the cars NVH, but amazingly we could not detect any more noise, vibration or harshness. Perhaps it was because all of the old stuff was in such poor shape that it was all loose and rattly.

When letting out the clutch we were amazed at how smooth everything was and how the jerking and drivetrain snatch was nearly completely eliminated by the firmer bushings and pitch stop mount. The shifting went from awful to great since the free play in the shifter was gone. We could really feel the shift gates and detents.

Most impressive were the improvements in handling. The car’s body roll, pitch, and squat were all greatly reduced. Corner exit traction was amazingly improved with the better bushings, anti-lift kit and the rest of the suspension doing its job properly. The best thing is that understeer has been eliminated! Even the hard to get rid of low-speed understeer of AWD cars has been eliminated, the car now does 4 wheel drifts. Now our old and previously worn WRX can hold its own with some of the best handling cars in the MotoIQ fleet!

If you have an older WRX you owe it to yourself and your car to refresh those worn out suspension components with Whiteline’s urethane bushings. Combine them with the Whiteline anti-lift and roll-center correcting kits and your car will feel better than new and handle much better than it was originally designed to. We highly recommend these parts.

Stay tuned, next we tackle the old worn out and beat brakes on our Project WRX with a significant upgrade from StopTech!

  1. I have a lot of the same parts on my 2005 WRX and absolutely love them. One question, if you needed to replace the rack is there a reason you guys didn’t upgrade to the 2015+ rack? There’s a bit of fabrication needed to make it work on a GD but I’m really glad I did it.

    Keep the GD WRX updates coming, I’m really enjoying them.

  2. Hello MotoIQ. I’ve just wrapped up doing front lower control arm front, front ALK, rear lateral links, and lateral arm bushings from whiteline in my 1999 Subaru RS. I have already had the Roll Center Adjuster kit a few years now.

    I haven’t driven the car yet, but what is your take on these parts “binding”? There’s a lot of info about urethane binding on the net, but I figured Whiteline has taken this into account…or have they? Thanks in advance!
