A fellow I work with who is a mad oldschool revhead (Also Has a 265 Charger and a Javelin along with a BMW 635CSi) has recently turned his attention towards imports, and has gone and bought an Australian delivered Mitsubishi 3000GT, he's completely in love with the car, althought I think it's becoming apparent that it's quite hard to get bits for it. He's tried to get a set of mags for it, he did find some but it seems that they're one of those cars that are really hard to get bits for. Thing is, these cars are huge in the US, so if you're patient and don't mind dishing a bit extra for shipping there's a world of parts over there for 300GT's/GTO's.
BUT.... if you need to replace the calipers, it looks like they run identical Sumitomo's to R33 GTS-25t's/R32 GT-R's
