Go to dealer and ask them to search for these parts under E39 Aerodynamic package. I recently installed an M-Tech bumper for my 540IT, and they found them there, previously, the part guy kept searching under M5 bumper category, and couldn't find them.
Shawn, here's the link to the brake H/D mod http://www.bmwm5.com/greg/brake_ducts/
you might find some others that posted too...
But in that link the part #'s are listed, as for the rings they are from Home Depot, they are Sweethart sink drains.
I posted a pic of mine below. Keith
Hello guys,
It's with great regret that I have decided to list my Brembo BBK up for sale. I had a few family personal things come up and having the extra cash would really, really help. BBK is complete minus the caliper brackets but I can assist with ordering them directly from Race Technologies...
Unrelated and cannot vouch for seller but this seems like a good deal. I ordered one yesterday and waiting for it to arrive. The cheapest i could find was about $100 shipped.
