Which brakes would be better 215i twin pot or VT

[shanhsv]

Im thinking about putting better brakes in my vs Calais V6 but not sure which way to go about it. Theres no power upgrades and I don't go racing around everywhere, I just it to quicker when I need it to. With the vs twin pots can I just change the caliper, bracket and rotor or do I need to change booster and stuff as well.
I know vt brakes are cheap to buy but by the time I get the rest of the stuff for the conversion, it'll cost just as much as the vs brakes. Seems price wise there doesn't seem much difference.

VT rotors and pads would be cheaper with more options then a HSV only caliper in the end i reckon when you need to replace them down the line.

VT brakes with the VT master and booster.

That way you can still fit your spare wheel on.
Thats what I'd do if I ever bought another Pre VT commodore
