I very much doubt you will see any measurable difference in performance, same with gun drilled axles, alum spools and lightweight driveshafts. I did a same day back to back alum vs steel driveshaft test (13# vs 10#) and saw zero performance difference. That being said, unless you are on a budget, I would do everything within reason to reduce rotating weight regardless. For what it's worth, I just ordered a new 3rd member and paid the extra for the lite weight parts so am taking my own advice.
