well, I'm not gonna be hauling anything in the bed or towing anything, or doing any type of racing. . . ever. I'm building this purely for a fun driver. I put a IFS in the front with 2" drop spindles. I want it to sit a little lower than stock and handle descently too, so I want something in the back that will provide a good combination with the IFS. I figured some type of 4 bar or 4 link would be the best way to go.
If leafs would work ok with the IFS considering my goals for this car then I'd like to take that route because of the cost benefits and ease of installation.
