Speedway G-comp suspension

I love how folks refer to coilovers as "modern". The Mustang II suspension design, which pretty much all of the coilover conversions are based on, is 40+ years old too. They're just springs and shocks, there's not one thing fancy or more "modern" about them. Same for 4 link, 3 link, triangulated 4 links, all of those suspension designs much older than most people realize. The "Ram Rod" '49 Plymouth drag car was running a multi-link rear suspension in 1958. Ram Rod - The High And Mighty - Hot Rod Magazine

"The Plymouth also featured what may have been the first adjustable four-bar rear suspension in a drag car. For inspiration, the chassis committee drew from the Jaguar XJC, one of the last great live-axle sports racers. But with a twist: According to Ramcharger Bill Shope, the Ram Rod used a telescoping left upper link. The setup was intended to work as an offset three-link on acceleration, reverting to a conventional four-link under braking, when the slip-link bottomed out. "

Challenger's can be lowered more than A-bodies will using the torsion bar adjuster. The geometry on the E-bodies is slightly different so they have a little more available travel if they're at a comparable ride height as an A body. I had my Challenger lowered to the point that my above the steering link headers were only 3.5" off the ground. I raised it up about 3/8" from there because I got tired of dragging on speedbumps and driveway transitions. It runs 275/40/17's all the way around, 1.12" torsion bars, FMJ spindles, the B/R body 11.75" disks and an 8 3/4" rear. I even ran 2" drop spindles on this one for awhile before I realized I could lower the car that much without them. The limiting factor on running these cars low isn't the torsion bar suspension. If you run torsion bars large enough to actually handle the tires that will fit on these cars you can lower to the point that header and exhaust clearance is a problem for anything that sees any kind of street time. Here's a shot of my Challenger, you can see I have the tires well tucked into the fenders. And the tires on this one are only 25.6" tall.
