So Menscer wanted you to go stiffer than 250? They just want the spring to hold the car up to ride height with no energy in it. Yeah, there is a 9.4’s second ZL1 Camaro running in the class that has a good 500-600 hp on me and about the same nose weight. He’s running a stiff front spring, he doesn’t need any help getting it to transfer and the rate of transfer is within his shock tuning window. Each car is so individual.
