Driver Front:
Camber: -1.4
Toe: xx
Caster: 5.4*

Pass Front:
Camber:-1.5
Toe: xx
Caster: 5.7*

I would suggest running the Rear camber at -1.1 drivers side and -1.2 passenger side.

I don't have enough grip up front. Why would I want to reduce front camber?

My plan is to go with a front camber kit, and I think I'm going to try to run around 2.5* of camber up front. I'm also looking to go with a square setup, which should help dial out understeer as well.

Why do you suggest different camber on each side?

Less on the drivers side because with you in the car, it evens out

I do alignment with me in the car...it's the only way to do it right.

No not the front camber but the rear. Different camber on rears based on non adjustable control arms up front. It makes the rear the 0.3 difference from the front.

So if you have up front (drivers side) -1.4 then the drivers side rear should be 0.3 difference which places it at -1.1. Same would go for the passenger side, whatever the non adjustable front is then minus 0.3 and you get your setting for the rear camber. Therefore no matter what the fronts are reading on camber the rears would be 0.3 difference on both sides on the rear.

As far as the 0.3 degrees difference goes, thats about normal for a front engine rear drive street car. The reason you need more negative camber up front....that's because the car has a front biased weight distribution (as front engine cars usually do). That means that in corners, the front is going to have more inertia than the rear, so it will fight you a bit when you are turning. That means that it will want to understeer slightly. To fight that tendency, we add a little more camber up front than in the rear.

It's only a suggestion as it appears you have a grip on the issue and a sound plan of attack to resolve it. Don't mind my yammering, I am still learning this stuff and I know you have more knowledge and experience.
So as to not throw a monkey wrench into it, I will gracefiully bow out and listen and learn.

That's far too upright for the front, and especially the rears. I'm thinking about running 2.1-5 out back and 2.8+ up front. I'm probably running a more aggressive setup than most though.

Control arms here we come! Sounds good on the camber setup, front and back. Let us know how it performs.

I am going to get another alignment done before the run on June 18. I wish I had upper control arms...but the piggy bank was busted after new springs and tires.
