Less weight?
I don't think so...
Front disc brakes weight more than drum brakes, i think those rear disc brakes are the same?
If you go to drag race, weight counts...
I wan't those rear discs too 'cause my wife is an happy with the drum brakes at circle track, she love's to drag race and she love to race at circle track but our 10" rear drums get a little wild at the circle track...
Has somebody buy those rear disc and put it to the scale to get actual weight?
