IMO I wouldn't run the cargo coils as they are variable rate. I have always used stock springs and haven't had any issues. Old schoolers used to run a reg spring on driver and cargo on passenger to help with the g-body twist, along with the addition of an airbag on pass side. As for the 90/10 lakewoods, they been around a long time and I myself used to run them on the street with no problems but they are obviously not for u if ur planning on driving like ur racin on a road course like Watkins Glenn, LOL. The ones that are a pain in ur azz are the comp 3ways that can't be adjusted unless u remove them. Dbl adjustables are the end all answer but as tommy said-expensive. I actually have strange single adjustables on all 4 corners and they have been great. They have allowed me to dial in my launch and my reaction time. I went with the single adj since I didn't want to try all the different combinations that are capable of trying. And since my car always hooked, I was lookin for some more simple tuning that was able to be adjusted in the car with the turn of a knob instead of removing he shocks to do so. I see you are in Livonia, where are u planning on running? Empire dragway? I'll be there for the 1/8th mile shoot outs on Sundays. Look me up if ur goin there.
