I'm on B8s and swifts, and still feel like I'm on the front bump stops too much, so I've bought a set of new mounts, and plan to shorten them 1/3" or ~8mm. I've shaved the internal bump stop of bilsteins (b6) previously, on E46 m3, but am chosing this route instead since there's a known solution (besides installing camber paltes with thinner stack heights).
My father is an actual machinist, and I assumed this would be no big deal. His concern was that the steel bearing being encapusulated in rubber will deflect. He suggested just taking a hack saw to it, even attacking it from different points to ensure a straight cut, then cleaning up on the belt sander if necessary, would be best.
Perhaps the rubber is so stiff that it doesn't deflect enough, in the lathe, to be dangerous, but will the cut be even enough?
It also seems relevant to mention that even if the cut (by hand, hacksaw/sawzall) were not perfectly parallel to the top plane (top surface that mates to shock tower), the rubber will slightly deflect to correct, and not so much that it would cause pre-mature wear. Your cut needs to be good enough, of course.

When I did this several years ago, we chucked it up on the lathe and turned it down ~10mm, without issue...FWIW.
BTW...Most E36/E90 camber plates are same stack height as stock, or even a little taller, unfortunately.
