Since I finally broke down and bought some new tires, I wanted to make sure that I corrected the front camber that has been killing the inside edges of the front tires after I installed my Eibach springs over 10K miles ago. I was able to squeeze 11K miles out of the fronts by flipping the tires on the front wheels, but if I did not do that I would have only made it to only about 6.5K miles.

My camber adjustment was maxed out and sitting at -2.0 degrees, which I knew would kill the front tires for my street driven GTR. I wanted to preserve the ride so I was hesitant to go with new upper control arms with heim joints. Also those these types of adjustable front arms can be quite expensive. So I was searching on the net and found these inexpensive Whiteline bushings that noted that noted that I could add +/= .5 degrees of front camber. The bushings installation was quite easy and after getting a quick check of the front alignment, I did gain the .5 deg of camber and am now sitting at -1.5 degrees. My caster increased a tad bit, but is sill in spec and the ride has not been affected as far as I can tell.

If anyone is interested, I ordered the bushings online from Speed for Sale and they shipped from SoCal and arrived at my work in NorCal in only a few days.

Just ran into a very minor issue. On the front end, in addition to the new Whiteline bushings, I have the Eibachs and 20mm spacers. The Whiteline bushings pushed the top of the tires out just enough such that my tires rub on the inner fender lip when I hit medium sized bumps. I am going to try a thinner 15mm or 10mm spacer instead of the 20 mm spacer that I have been running for a long time.

Sweet upgrade.
Did you need a press to get the old ones out?
Were these hard to align?
How much caster did they add, this is a good thing in my opinon.

Yes, you need a press to get the old bushings out. I can see where it would be difficult to align, but since I was looking for maximum adjustment of reducing camber it was quite easy to do. I noted that the bushings are asymmetrical, so I decided to install them such that I was getting near to stock caster. I saw less than a degree of increased caster. However, if I were to flip the bushings, I can see getting much more caster, as was one of the goals of Whiteline as quoted below on their description of their parts.

Caster is the backward or forward tilt of the steering axis. Vehicle manufacturers are aware of the advantages of caster and as each new model is released the amount of caster specified increases. High levels of positive caster equate to dynamic negative camber on turn when you need it most. Whiteline continues to put heavy emphasis on additional positive caster when designing new suspension packages.

Looks like you have the bushings set to the max caster position, as the inside of the A-arm is moved toward the rear due to the thinner bushing being toward the rear of the car. Moving the upper A-arm toward the rear will increase caster as it tilts the vertical motion axis rearward. If the bushings were equal thickness, you would get stock caster.

This is the exact setup I was thinking of doing. I'm glad I read the post. I didn't think the camber would be that crazy with the modest drop of the Eibachs but -2.0 is pretty hefty.

At -1.5 I hope you are seeing some better tire longevity.

Assuming you're liking the whole setup now that you got your spacers dialed in too?
