Dont get your hopes up too much. They definately make the car feel more solid in the rear when lauching, and help some as far as launch goes, but the thing that helps me the most with the launch are the front struts and no front swaybar. That lets the front lift quicker to put weight on the rear. I also put a bigger rear swaybar on the car to keep both rears planted evenly. I already fixed the torque box, but I'm going to get that kit to really strengthen it. Im waiting to see if I can get just replacement bushings or If I need new LCAs.
Im building my car for the strip, so I'm setting the suspension up for the launch. My friend has a bullitt mustang, and he is setting his up for maximum autocrossing, therefor better cornering, but were both getting aftermarket control arms to keep the rear in the right spot.
