Now we need you to weigh that AFAM rear sprocket and see the difference for us, please? I know on the 636 going +2 on an aluminum was a huge difference (636 is 520), maybe as much as 4-5oz just by judging the feel. After weighing the rotors I'm hesitant to go away from the steel rear if Sunstar was able to make the carriers for the rotors so light...maybe the sprocket is light too?
Personally, I did tell a slight difference going to the rear wave and Ti rotor bolts/rear caliper bolts, but I also set my preload correctly on the same day...which could be a better explanation...sorry.
I still want to change the front caliper bolts and pinch bolts to Ti, maybe the rear axle nut too. I was lazy and didn't weigh the sprocket nuts, but could weigh the stockers...I put aluminum sprocket nuts on the 10r.
Since I wont be getting the rotors and I've heard the Brembo isn't worth it, woodcraft rearsets it is!
