Default Bad nose dive after strange coilover install

Well im not sure what i need to do so any help would be great, i just installed strange SA coilovers with 275 springs. When i ran Friday night and got to the big end as i got on the brakes hard the front end seemed to nose dive more than normal and the air dam drug a little. I have the front right height set to 26.25 and the front left set to 26.75. Do i need to raise the car some more??

Also i have a bmr torque arm and the mount for a th350, i have the cross member mount for the torque arm set all the way at the bottom, is that ok??

How many clicks were you from full soft? Front end of the car also might be heavier than you think for 275's.

The part number is S5271. I ran them on full soft the first pass thats when it did it. So I tried turning them up and still did it, I did get on the brakes pretty hard but ive never hit the air dam before doing that. The car weights 3085 without me in it, and that was before removing the power steering, so maybe a few pounds less. The battery is relocated to the rear, all the ac is gone, and front bumper support is gone.

I would have guessed the full soft to be part of the issue. What is the ride height in the back?

Stock spring cups still installed or removed in the rear? When you say you tightened the shocks down in the front how many clicks did you take them in from full soft?

If it is clarksville I run there on occation and don't bottom out on the brakes but I take long way around.
