For anyone after an Exedy clutch you can call Kevin on 0296730988 who runs "SBC" (Specialised Brake & Clutch - located at St Marys, Western Sydney).
He has organised group buys before (DBA Rotors etc) and is currently working on a new website displaying his products. I've found his prices to be quite nice and he also has displays at car shows, drag racing, trackdays etc.
Give him a call, tell him Ben sent you or mention SAU and he'll fix you up with no BS.
PS. He has asked for information on sponsoring SAU formerly but did not recieve a response from any Admins otherwise you'd see his banners splashed across SAU everyday
