First off, I'm with the other guys about running leafs because they're so darn cheap and easy.

If I wasn't going to run leaf springs on my cars, I'd do a truck arm setup.



Truck arm setups are simple, easy and effective. NASCAR guys have used it for years. It's even popular with some of the grassroots pro-touring guys. It is basically the 1963-72 2wd Chevy truck rear suspension.

There's lots of information about them out there on the internet.
