That modern look....

I pretty much assumed they were. There's no way they're streetable at the height shown in the pictures, and that usually means they're bagged.

Which is fine, as long as you don't mind springing for the Alterkation K member, 4 link rear and airbags. Which I would wager would cost close to $10k, just in suspension parts. It costs a lot of money to look that cool...

The torsion bar and leaf spring rear can be made to handle just as well as a coil over set up, and you can get pretty low and still be streetable. But you definitely can't get THAT low. And I still think that you can look pretty darn good and handle really well with a set of 18's without going the airbag route.

I agree, there's nothing wrong with installing an air ride suspension. The Demon is an Alterkation (I think you mentioned that before), but I don't think they offer an airbag kit for it anymore. Ridetech only sells them for LX, B, and E bodies and they are very expensive.

A lot of people in the import crowd do it for the look when parked. Get the car as low to the ground as possible so that the wheels barely don't touch.

I agree with the Torsion bars and leaf spring statement. Great thing about the T-bar suspension is you can adjust ride height without swapping springs. Just look at cars like the Green Brick or the Red Valiant (now known as the Red Brik). Both successful track cars utilizing stock suspension points that look good and run 17" wheels. I'll be going to 18" wheels within the next couple months with my torsion bars and leaf springs, hopefully. It should look nice. I'm excited. :D
