I believe you will hav the to upgrade the brakes yourself. No real point going from the sv6 to the SS brakes in my opinion.
The 'super duper brakes' are Brembo's which can be upgraded aftermarket which is probably a good option. For the VE you could import brakes from the American Cadillac CTS-V which are Brembo's front and rear. You could even import 6 piston front 4 piston rear with only having to change one minor thing. Not too sure if the brakes are still compatible with the VF.
A forum user by the name of Bonners is probably the best to talk to or GSL rally sport (sponsors).
