Does anyone have the spring seat heights for LS 400 shocks? I want a set of B6s on my 430! Bilstein tuning should be fine since the weights of the cars are close, along with F-R distribution. I know they use a stepped bushing sleeve on the bottom of the rears on the 430s and sleeve widths may be slightly different, but those issues should be easily overcome. And if I end up with an inch or less drop, I’ll be happy. I realize spring rates have a lot to do with these types of modifications but I’ll take that chance. It also appears the extended and compressed shock heights are not the same, but they are close, and it’s another chance I’ll take.
