Here is some info from the research I have done for myself and also Ash (Secaboy). Please double check listed part numbers before ordering. Rotors:- Front Genuine rotors are modified PBR Corvette C5. The PCD holes are elongated to give us the required 5x114.3mm PCD instead of 5x120mm. Also the rotor has a hub locator ring fitted to reduce the centre diameter from 71mm to 62mm. Part numbers to be updated. Aftermarket rotors for the TRD Aurion are not available as a direct replacement, C5 Corvette rotors are available from DBA & RDA. These rotors will need to be modified the same as the genuine PBR sourced rotors. DBA part number is DBA 067 (standard). 4000 & 5000 options available. RDA ??? Rear At the moment it looks as if genuine is the only option. The genuine rotors are PBR made. Part numbers to be updated. Pads:- Front & Rear Genuine pads are PBR sourced. In the sales literature for the TRD Aurion they are listed as Ferodo HP1000 compound pads. The pads themselves are marked PBR performance, which are according to PBR literature capable of being used from high performance street up to and including club level motor sport. These pads are quite hard on the rotors and have a very high dust output. Aftermarket options appear to be very good as the pad shape for the TRD Aurion is shared with the Corvette C5/C4, some HSV's and the XR8 Falcon. I have found the best way to find pads is to look up '01 C5 Corvette for the front and '96 C4 Corvette for the rears. i) Bendix part numbers are F) 7599 and R) DB1354 ii) Hawk Performance part numbers are F) HB247x.575 and R) HB112x.540 x=compound, Street compounds F=(HPS) High Perfomance Street, Z=Performance Ceramic. iii) EBC part numbers are F) Red Stuff - DP31162C or Yellow Stuff - DP31162R and R) Green Stuff - DP21167 or Red Stuff - DP31167C or Yellow Stuff - DP41167R Currently Im using genuine rotors front and rear with Hawk Performance Ceramic pads. I have found these to be much quieter and a huge reduction in dust compared to the genuine pads. After almost 5000km I do feel that these pads are also as good if not better than the genuine pads in braking performance. I have had one small issue with the anti squeal shims on the inside rear pads moving and causing them to touch the back of the park brake drum. They appear to be just attached with a double sided tape and the piston does not press squarely due to shim being a different shape to what is fitted to the genuine pads. They were easy to remove and would recommend anyone using the Hawk pads to do the same before fitting.
