But the rear was bad outside was 80 middle was 90 and inside was 119 all that with -3 neg on the rear.
I will be ordering the SPC kit that takes -1.25 degree maximum out
I guess, I will settle for -1.75 on the rear.

Great!!! ... once you get the tire temps optimised by getting your camber right, you know that you have got your contact patchs close to optimised. To help initial turn in, you can play a bit with front Toe out to get the response you are looking for.
How low are you on the C/O's ... anything below 1" of drop and the roll centers start to get funky ... beyond 1.5" they pretty much go below-ground. You have to go nuts and compensate with high spring rates to keep the roll moments minimised.
I would reccommend that you get the car corner balanced ... this will allow you to better analyse what is happening (from a handeling perspective) as the car will respond evenly and repeatbly under all conditions (RH / LH corner Braking / Accelerating) This will help you make educated decisions on what next in the setup needs to be addressed in each stage of the corner (Entry / Mid / Exit)
You can then start to look at Spring rates, spring rate stagger (F/R), swaybar sizes and stagger, and Damping to tune the transitional and steady state charateristics thru all stages of a corner.
