Is it the UCA or the Spring???

I need some help y’all, I’m building a bracket car for the wife and I’ve run into an interesting situation. Long story short, the new springs have pushed the car to the stops on the UCA. I’ve tried two different sets Moroso “Trick Springs” currently on the 47130 spring. This is the lightest spring Moroso sells for our cars and it’s still on the upper stops with the motor installed (see pics). Too many folks run this spring for it to be the issue (I think…). So now I wonder about the design of the Summit brand UCA? When my buddy and I (400lbs total) stand on the frame horns I only get about 1” of drop. I won’t be adding that much back to the car in sheet metal, WTH??? Here is the current configuration with links to the parts being used, any help / recommendations would be much appreciated

Most of the threads I see about the moroso springs, everyone says the trimmed them to get the ride height where they wanted it. Could these be made long for that purpose? Or are they supposed to be direct replacement springs? I know nothing about the moroso springs.

Moroso springs usually need to be trimmed by cutting a half or so coil at a time. But if you don't have all the weight on the nose "WAIT" till you do. Let them sit at race weight including the fluids too for a day or two. The springs will settle some. Then trim the springs 1/2 coil at time till you get your desired ride height. Hope this helps.
