QFM (Queensland friction material) are an Australian owned company. K500's are a "sports" pad (rated from 0-500degrees C) and have a very nice bite to them, even when cold. Last time I was able to get my hands on some, I think they were around the $125 mark for a set, but for that price you can get A1RM's from gsl rally apparently.

My brake supplier has started to wind down stocking QFM parts, as apparently for OE replacement pads, there has been alot of issue's with noise & dust complaints (not 100% sure exactly).

For me personally, it is not worth shipping pads interstate, when there are fully fledged companies who can do it for cheaper including shipping (as they already have active accounts with freight companies, that I do not)
