just make sure if you get them cut you take them to a place that does drums all the time .
i have seen places try to just do a fast cut on the drums and call it good .
well that's not good .To rough of finish is bad. The car will take longer to stop as well.
Drums need to done in two steps 1 cut fast clean up and 2 slow finish.
Don't accept any less.
also try adjusting shoes up to where the drum can't be removed easy but still spins with slight drag.
