Let me start by saying I'm dropped on Eibach Pro-kit... after getting an alignment, here are the results:





1.) What is SAI and Included Angle? Why would the front right side be perfectly in range and the left side be so out of range? How do I correct SAI/angle?

2.) Why is their such a large difference in the front left and right camber? I can deal with -1.5 (it's only 0.3 out of range afterall), but the -2.0 on the right side is pretty extreme.

3.) What are my best options for correcting the camber in the front and rear? I've heard of SPC, Cusco, Stillen and SLP (which I can't find SLP anywhere when I search). Is there one that is more reccomended over the other? Also why are they so expensive? This is my first Nissan product, I've previously owned an Integra GSR, Prelude, RSX, Civic Si... all of which I am used to paying like $200 to get all 4 wheels in alignment. Ths G35 products range from like $400 to $800 for only the fronts?!! That's brutal...


Thanks for the help everyone.

 

its SPL.

thje camber adjustment in the front is very limited, so thats why theres a large difference. You'll need front control arms to fix that. Like you said, they are $$$ (~400), no way around that.

rear arms are cheaper (~100$).

These arent 15k$ hondas. you pay alot for the name and parts follow suit.

it all depends if you want to spend 500$ or just want to replace tires sooner. 2 degrees isnt all that extreme, but not the best handling either.

 

SPL... got it... lol, yea that will make it a little easier to find if I had the name right to begin with. I just purchased a brand new set of Michelin PS2's that ran me around $1250 so I would definately like to preserve the tires.

Pricing on most everything else I've looked at has been fairly comparable, so that's when I saw the camber kits my jaw dropped... oh well, if it's gotta be done it's gotta be done, the car looks 100x better dropped so what's a few hundred bucks more to get it properly aligned? So is there one brand that stands above the rest? From what I've searched around and read, SPC people have sensor issues and lights on the dash, Cusco don't have enough positive camber adjustment (though SPC appears to be .5 positive adjustment as well?)...

And anyone that can answer my question about the SAI/angle thing would be a great help too. Thanks!

List and explains all terms

SAI/Included angles are the result of the springs/shocks angle changing vs true vertical.

Did you get a reference alignment the day you bought the car to make sure it complied with FSM NOMINAL brand new? Buyers forget that a brand new car may not meet specs due to boat/truck transport to dealer or never perfect from plant, always pay to check brand new.

The other problems may be the alignment machine itself when was it last calibrated?

 

No I did not check the car when I purchased it, I am not the original owner. I picked it up and brought it over to my local Infiniti and Nissan dealership (I know the managers) and had them run an inspection on it, same as they would do as if they were going to certify it for resale on their lot. Everything checked out, though I never asked for a printed sheet of alignment specs or anything else. I also didn't have the car aligned at any time prior to dropping the car.

As for the alignment machine... I can only assume it to be true. It's at a local Ken Towery's Autocare shop, the manager there heads up the local SCCA events, thus he discounts and caters to almost everyone locally that either runs SCCA or on the local car forums.

Back to the SAI thing... from my understanding, a variance between the two numbers may be an indication that something is bent? What exactly would I be looking for? I'm not experiencing any pull at any speed, car drives straight. It's the number itself that raises my paranoia.
