What onzedge has written is good information and should absolutely be followed.

I just had Swift springs, SPL camber links, and SPC toe bolts installed yesterday. Today, I had the car aligned. The tech was able to put the rear wheels almost exactly in the middle of the stock alignment specifications, which is probably adequate for a car that is not tracked (-1.7 / -1.6 camber and .12 / .13 toe). I'm sure the SPL/SPC parts guaranteed this outcome, so I recommend that you get these parts if you get the Swift springs. It's the smart way to go for $300 in parts.

The front wheels, however, are a different story. The front camber and caster are not adjustable unless you buy the SPL front upper arms, which cost $700+. Most people choose not to go this route because this will effectively double the cost of lowering your car. Also, they are not as necessary as the rear suspension pieces.

Anyway, the tech was able to set the front toe just about perfectly (.07 / .08). Excellent. The caster is 5.1 / 4.8. The left-to-right variance is a bit high, but okay. So that brings us to camber. I knew beforehand that the negative camber would increase when lowering the car. I had the car aligned 700 miles before I installed the springs, and the front camber was -.8 / -.9 at that time. The max spec is -1.4, and I was fine with going to that point or even slightly higher (maybe up to -1.8). What I didn't expect was the cross-camber variance I got of .5 (-1.2 / -1.7).

Again, as far as I know, the only way to change the camber and caster on the front wheels is to buy the SPL front upper arms.

So my questions are these: Is there any detriment to having cross-camber and cross-caster variance? If so, how big does the variance have to be?

I hope that people will find this thread useful and that it will save them time when researching Swift springs.
