Jess,
High Performance world imports AVO's, reasonable price, Ians manual should have part No.s (02) 9630 2333.
If you have the $$'s go for Koni or Ohlin.
High Performance also import Wilwood master cylinders. Race brakes worth talking to as they will match bore size to the brakes you want.Best if you sort brakes and master cylinders together.
Go for the best quality brakes your budget can handle. Also recommend braided lines.About $6K for quality calipers and rotors all round.
Make sure the float switch ( for the brake fail light) screws onto the master cylinders. It dosent with the Wilwood which requires some modification.
Congrats on picking a CR. THere are plenty of CRs on this forum in various stages of build so feel free to ask for advice.
