Wow, thankyou everyone here for the quick replies. The Australian dealerships over here can get almost any part, but they are often very expensive. I normally get my parts from bmaparts.com in the USA, and after shipping costs and buying the parts they work out to be about 50% off the australian BMW dealer cost. Also buying rare parts from a BMW dealer in Australia often takes up to 4 weeks to ship them over from Germany, so its a lot cheaper and quicker for me to deal directly with gentlemen who sell the products directly.
Do the heat shield rings come with the caliper rebuild kits? If they don't I assume that I can re-use the old rings for the new pistons. The pistons and the rubber boots look okay at the moment. I just want to rebuild them so the calipers are new again.
