I have had the Eibach drag kit and it worked good. It comes with one bag, so just put it in, the springs are tuned for it. My only complaint is that the front sat way to high. I would cut half a coil off to start before you even install them. Also, they are a pain in the *** to get the fronts in since they are quite a bit longer than the stock springs.
I don't know if you will be able to pull the tires on drag radials though. But I've had both, and the Nittos work well and last a long time, but the BFG's work a little better, but don't last even half as long. If you want to pull the tires, buy some slicks.
