To get the wheel openings down to 24" and still have suspension travel you'll have to use drop spindles. With the standard spindles even using 1.12" torsion bars won't be enough to keep off the bumpstops. My challenger sits at 25" to the tops of the wheel openings, and even with 1.12" torsion bars and short bump stops I still bottom occasionally. Not enough to require raising the car, but I can't go much lower. I only have about an inch of travel from the frame to the bumpstops at that height. The travel at the wheel is about twice that, and I would consider that pretty close to the minimum for a street car. But to get to 24" you'd only have about a half inch from the frame to the LCA, and the control arms would be at a pretty severe angle. You'd have less than an inch of up travel on the suspension at the wheels. Your tires are taller than my 275/40/17's too, so your really your numbers would be even worse to get your ride height that low, I'm basing the travel on my car.
Not sure what you run for exhaust, but with headers and that fender height they'd be less than 3" off the ground. For a static height that's just too annoying. I ran my car with about 3.5" from the ground to the header flanges for awhile, it was a pain in the butt. The headers dragged on every speed bump and parking lot tradition. At 25" to the wheel openings the header flanges are a little less than 4" off the deck on my car, which is enough that they don't constantly drag. I knocked my entire exhaust system off my car on a speed bump when I was running at the lower height, I had to fully weld the entire exhaust to keep from pulling it out of the clamps all the time. You can do it with the drop spindles if you want, but it's not going to be practical if you're driving the car frequently on the street.
