I did do back to back test on steel (13#) vs alum (10#) driveshafts, zero improvement. In my case, I have a pretty low HP high RPM combination so if anyone would improve, I would have thought it would have been my car.I also have all the lightweight rearend parts. I really don't think there is any performance difference in any of it. That being said, if I were starting over, I would buy the lightweight stuff anyway. It just seems that intuitively it is better to have the lightest rotating parts regardless. At least it gives you the opportunity to run lighter or put sprung ballast in the car if needed.
