Will Slotted rear rotors help with nose dive?
I've never seen such small and sad looking brake pads for the rear, it's no wonder these cars nose dive so bad when hitting the brakes. I have new blank rotors in front and I'm willing to try anything to get the brake balance a little better so it doesn't nose dive so bad. I've replaced the springs and struts 500 miles ago. Will the slotted rotors help the rear to grab a little more than the front?

Changing rotors in the rear has nothing to do with nose dive. I will tell you right now that if you change the rear rotors, you'll still get the same dive. Slotted means little for actual brake distance and front/rear bias.
If you want to reduce nose dive, then either lighten up the front end of the car, get insanely large brakes setup in the rear (which would upset the braking balance considerably), or firm up the front suspension via stiffer springs and/or higher damping shocks.
My friend has the NF210/KYB combo and they a very soft combo. Basically just a bit higher spring rate than the OEM springs. You're going to get nose-dive with this setup unless you get something else.

Nose dive is more a function of weight transfer and suspension geometry.
The front brakes do most of the work anyway, so having the weight mostly
transferred to the front wheels is actually desirable.

Yes, suspension stiffening is the best way to stop your nose diving, however, if you do manage to divert/increase braking force to the rear you will severely reduce your braking distances!
Your cars front brakes have between 65-75% of your cars total brake force, so when you hit the brakes the cars center of gravity shifts forward and forces your tyres harder into the road. Just think of the days on your bicycle, when you jammed on the rear brakes the back wheel skidded and when you jammed on the front brakes you stopped very quickly as the center of gravity pushed into the front wheel and into the road.

Correct me if I'm wrong, there are ways to adjust the power distribution of the brake power between the front and rear brakes within the master cylinder by adjusting the proportional valve.
