    I just wanted to give you kiddies some word since I am bored.
    The STi rear knuckles allow more camber adjustment than our regular Impreza L/RS. I noticed this when we where replacing a friend's '04 STi rear strut tower. We gave it TOO MUCH camber when we put it back together. I thought this was pretty neat because I was never able to do this with my Impreza L wagon.

    NOW I also have the whole STi rear knuckles on the BC Racing Coilovers. I am able to go MAX negative camber; more than my stock L knuckles. What I did was had the car on jack stands, use the floor jack to load the knuckle via jacking it up before tightening the two 19mm strut bolts/nuts. This gave me abouts 1-1.5* negative camber.

    Nice to have an advantage with STi stuff. ALSO the front ball joints are different between JDM Spec C and regular JDM STi because of their control arms. JDM Spec C has aluminum control arm which uses a different ball-joint(same as USDM STi w/ aluminum control arm), and regular JDM STi uses the same ball-joint as WRX/Impreza for steel control arms.

    I'll get some pics of the camber in the rear.

    Those control arms can be flipped giving you .5 degrees more caster then stock. I believe that applies to 04-06 USDM STIs only. The control arms where changed for the 07s removing a good portion of caster.

    Eibach camber bolts give me up to 1.75 degrees of negative camber in the rear, and they were only $28 ;)

    Put in some of the whiteline rear subframe lock bolts. It helps align the subframe and keep you from having too much cross camber. I'm at -1.7 and -1.5 L/R respectively if I remember correctly.

    I will eventually.. but when I installed them seeing as there was no adjustment per se I pushed with one hand and used impact with other.. where it tightened is where they stayed ;)
