How low can you go?

Rjs - what kind of ride quality do you think you will end up with those rate springs. They "seem" pretty stiff. What are your usage intentions for the car? How much suspension travel will you have front and rear? I know you've made extensive alterations to drop the body down as I've followed your build since day one... your another one that needs to get busy posting up some updates!
I'm trying to set my car up to be a jack of all trades so it will suffer in some performance aspects more than others, but, handling is my foremost goal.
I set my ride height up for 25.25" at the front wheel well lip and 27" at the rear wheel well. That will give me 5.75" clearance to the "lowest hanging fruit" under the car, one of which is that damn dropped sump oil pan. Wish I had the $$ for the new Milodon road race pan but that gold finish must be 24K.
