Those with the front SPC camber kits, how much camber do you have now after the install? Also, please mention how much your car is lowered.

Those with the rear SPC kit, has anyone gotten their camber to -1.5 without issues? -2.0 is too much for me in the rear.

I prefer factory alignment specs is possible.

My car is lowered 0.75" front and 0.5" rear. I have SPC front and rear kits. My alignment is for aggressive street and occasional track use. The specs are:
-2.2 front (toe neutral), -2.0 rear (toe -0.15). Seems to be working well for me.

Bringing the front camber to around -2 will greatly improve turn in and reduce understeer. In the rear, -2.2 is the inner limit of acceptable camber range according to factory.

The SPC kit can add a lot more camber than it can subtract. Before I lowered the car I was at about -3.0 front, -1.6 rear, but you could probably get between -1.5 and -2.0 up front. Lowered it could be more difficult to get the front within stock alignment range with the SPC kit.
