I assume your car is a base car (1997 in your sig). I have a base 986. Running base 987.1 cast hole rotors in front (saves 1lb per corner over oem 986 rotors). Zimmerman 986 drilled rotors in back. Can’t run base 987.1 cast hole rear rotors in back unless you want to give up the parking brake. I have no issues with stock size base pads.

Weight savings is over new rotors. Apple to Apple comparison. Used rotors have material removed, so the weight diff might be closer to 8oz (just a guess)
