To elaborate on the VE kit.
The calipers and pads are VE items, the rotors are not. They are specifically for the intended model to suit the VE calipers. I believe the rotor to suit the VR-VS is actually a Ford Territory blank drilled to suit the Commodore PCD. The VE being twin piston and having less displacement as the VT caliper gives increased pad pressure over standard VR-VS calipers.
The VB-VP kit comes with hubs as well so that the rotors become "floating" like the later models.
The VE kit comes with either 298mm or 322mm rotors, 16" is the minimum recommended for the 298mm and 17" for the 322mm. These days it's less of an issue because most people already have larger rims anyway. The rotors are also curve slotted and dimpled.
It all comes down to what people are prepared to pay when upgrading brakes. If you want to spend a LOT more time and replace more parts and don't want to spend the money on a true caliper and rotor upgrade, then go VT. But the VE is a better option as it works straight out of the box without having to cut and shut anything else on the car. There is no need to modify mounting brackets for boosters, or pushrods for the m/cyl.
I am all for DIY, and especially for saving money. But sometimes people will pay for the convenience of a 1 hour job as opposed to spending less but having the "upgrade" drag into days chasing down one problem after another.
Good on you for doing it on the cheap, but you are still yet to get it working properly? I'm not knocking anybody for choosing to do a VT upgrade, I only pointed out there is a much easier and better option available.
