thanks. looks like i'll just go with a set from lisle.

you're right about the set screws. BMWs are hex patterned and
can sometimes round out. removing them early on and using some
anit-seize will cure this every time and you'll never have a
problem again.

that also bring up an interesting point - if VWs have them, why
not audi?
