For a DD notchback, what would you recommend? I like the idea of the IRS since I can make some money back with the sale of my old rear, but is it the better choice? I want something that will handle well, ride smooth, and be able to hand some power. I'm not that worried about the drag strip anymore, I just want a car that rides smooth. I have a drag suspension on the car now, and I'm becoming sick and tired of the crappy ride/handling the car has.
