hey andrew. i see you’re in brisbane i bought my first set from a brake specialist in Capalaba while up there some years back, but recently got slotted RDA rotors and EBC red pads from my local PEPS auto parts.
i did all the enquires first with RDA in Brisbane who referred me to PEPS down here in southern sydney.
look up rdabrakes.com.au
footnote: after a month of bedding in the discs and pads i did some serious braking at speed down Bulli Pass south of Sydney, those who are familiar will know how steep and long it is and it’ll test how much brake fade you’ll get by the bottom, i was extremely pleased with how good they performed to say the least. all up they cost $550. well worth it
