Now i run KYB KG4741 with 309 psi Moog spring (can't find the number) cut at 12 inch . It's pretty stiff and not bouncy at all . It give 2.5 inch lift . I run this setup for stage rally but it's streetable . KYB KG4741 are stiffer than Bilstein 24-025386. The shock valving and spring have to fit together in order to have a great ride . If the car is bouncy le shock valving is to weak for the spring rate .
