I've threatened it several times with my big car aluminum front drums...but never pulled the trigger. They had quoted $265 each plus shipping at the time. I think there is another company that does it, but J&G is the one most folks know.
Had a set done by them. They were perfect when done. Not cheap but I thought price was ok. They also arched some shoes for me for those drums. I also got some rear aluminum dru.s from a G body done there for my GS.
Yea they quoted me $305~325 each,...can't justify that much on drums for this particular car,..I did however order the MP 11in rear drum kit
