Good debate guys. I have no experience with coil-overs, but if they require frame mods, I don't want to do that.

I measured the ride height. I get 9" in the front and 12" in the back. Not sure how its showing 9" in the front, with the front wheel so deep in the fender? It's a 26.5" tire in the front, so maybe that comes into play? The back is raised 2.5" to clear the 275 Nitto drag radials. It doesn't hop or hit the tires, but is a little stiff out back. I would have to change the rear tires to take the spacers out of the rear suspension.

How do you choose springs when going from a drag set-up to a road-handling setup? I'd like 9-10" in the back and 8.5" in the front with it all sorted out.

From what I've seen, every car is a bit different, so it's difficult to make a blanket statement for ride heights. 1 inch drop springs can do a lot of different things depending on what springs were in there to begin with, and how worn and sagged they are. Most aftermarket springs advertise a 1 inch drop, but I'd bet that they all sit different.

Anywho, my recommendation is to try to find some pics of cars that are running the suspension setup that you're interested in.

Relevant ride height specs for my car:
67 LeMans
SPC springs
Front: SPC upper/lower control arms, full stack of SPC spring shims, 0.5" taller lower ball joint, Bilstein HD shocks, Hellwig front sway bar
Rear: UMI boxed LCAs, UMI rotojoint UCAs, 69 Chevelle 12 bolt, Hellwig pro-touring sway bar
Wheels/tires: Trans Am Race Engineering Superlites, 17x8, 4.5" backspace, 0 offset. BF goodrich SportComp2s 245/45/17 25.7" diameter
Last pic wheels and tires have same specs but are Cragar Soft8s and Firestone Firehawk Indy500s.

I really like that stance! What is the ride height?
How do those wheels/tires fit the wheelhouses? Any rubbing or did you have to roll any sheetmetal? My Ford 9" is stock width at 60" drum-drum. Is your rear 60" wide?

Just started pulling the steering linkage apart. The center link and one tie rod end is wasted.

While I'm in there, I'd like to swap the steering box for a quick turn box. What are my options for a bolt-in quick turn box?
