If you were to then run that same spring with a true type rear, that bumps things up to over 3.00 hertz. Based on my calculator, you would need to go back down to 7-5k or 400lb to 300lb spring range if you wanted the rear to feel the same as when you were running the divorced set-up with 13k/750lb springs. I don't know how aero effects this as I have been focused on autocross, but I imagine you need to run on the stiffer end of the range since you have a force pushing down on the car.
I would love to see what he comes up with. Have my math checked so to speak.

Thanks you input as my friend as there is a lot experience on here singularly and collectively. I want to respect Dan's consulting and so I will let you know what he provides me given our agreement once I give him all the data he has requested. I will tell you this! Your calculations are totally in line with his rough estimate..."Quick math is lettings me like if you have 14k front springs, you need to be around 5-6k in the rear."
Cheers!
