My local ABS brake shop has quoted me $169 per MX83 rotor. The 4 Brembo rotors are going to cost me AUS$570 (Inc freight) and be delivered in 3 days.
I'm not worried about the delivery taking longer, so I'm now waiting on a price for the "6 week" delivery time.
With these prices, the Brembo's will be cheaper than the local alternative.
Please let me know if / where I can get a better price then the ABS quote. I'll be calling a few places tomorrow to make sure I'm getting the best deal. I agree that each manufacturers standard "lumps of iron" must be pretty similar in quality, but if I can get the "best" cheaper, then why not.
