Maybe I'm reading the sheet wrong but it says current camber -2.4

Yep that's what it says. I am not a fan of my wheels cambering, which is what I am getting in my rear. It's not even about the tire wear it's the look. I was happier with my stock 18s and spacers.

Camber arms will get you were you want to be. I run -2.7 in the rear but I like how it looks and my wheels are flush. I could go more towards stock camber but then I would need to install toe bolts.

even with less of a camber, you'll need spacers. Those wheels won't look as good without spacers

Not sure your driving style; mine is more straight line/with wide open acceleration from a stand still.... I'm only running about -0.5*rear camber & factory-0.8*F
I'm sure your alignment guy dialed the eccentric bolts on the camber arms as much as he could (shortened distance,to pull bottom of tire in) they have markings on them,,,,but when you go more positive on the camber (wheel lean out) you in turn give yourself more toe (wheels point in) .
Your toe setting is great; I have basic Kinetix rear camber arms from Z1 & have them shortened as much as I can (without having too much + toe)
My toe eccentrics are adjusted all the way negative & I adjusted the camber as far positive as I could, without letting toe get too positive.
One adjust directly affects the other.
As far as the front,upper arms are needed for that correction.
Good Luck & be sure your Toe adjustments stay very close to where they are now.http://uploads.tapatalk-cdn.com/2016...b6a87b6f85.jpghttp://uploads.tapatalk-cdn.com/2016...240df07a63.jpg

I have the SPL upper control arms and the lower bushings too. As for noise. It's no worst then a noisy set of tires. I can't really hear the increase in noise. But I can fell the difference in steering feel. :tup: :driving:

For alignment settings. -2.4 in the rear is a lot unless you are tracking the car or going for the wild camber look. I'm tracking mine with 345/30-19 on a 12" rim with a camber setting of -1.75.

Thanks for the help just got my spl package today. I'm going to have them installedo Friday then get the alignment. This may be a dum question but do I have to get all 4 wheels aligned or just the rears? I have my old h&r spacers and will see how the outcome looks. Worst case scenario I will use them. I ll post pics after the install

All 4 yes. I've been there and I've asked the same question.

Yes, do all 4. Because your thrust alignment may be off. When you set to rear toe, the front toe will be off in 98% of the time.

Also, you never even mentioned your wheel or tire specs?
