I have r34 calipers and r33 rotors for $400. Front rotors are 296mm and off the top of my head I can't remember the rears. From memory I think the r32 front rotors 278mm, so this is a worthwhile upgrade. Front calipers come with pads. I can't remember if i have rears, I can't look into it right now as i am at work.
Located in Ipswich, but can drop off to springwood.
Cheers Jason.
