yeah, they are very heavy! I think the fronts are about 45 lbs, and the rears are almost 50 something pounds! It sucks power that's for sure.
I think if you take 10 lbs of Rot. weight off it's like adding 1 hp or maybe its the other way around, 1 lbs = 10 hp. I don't feel like doing physics problems now, maybe tomorrow I'll figure out how many watts it saves. either way a good forged wheel can shave 18-20% off your cars' unsprung weight which is great for the suspention and making hp...
