I just ordered a rear Bilstein shock from Tirerack. It seems that there's NO brokerage fee for orders < $100! Tirerack appears to have an arrangement with UPS where you pay all fees including GST upfront so that there are no costs COD. Even for orders > $100, it seems that they charge a greatly reduced brokerage fee.
They carry Brembo rotors but not PBR (they carry Hawk). On another note, I just went from PBR Metal Masters to Axxis Ultimates. Both are made by PBR, but the Ultimates seem to produce a lot more dust than the Metal Masters. Now I miss those Metal Masters
