You would need the VT booster modified to fit the VS.

The VS booster will be fine to use.

Just put the diff back together and fit it to the car. When it comes time to fit the brakes, fit the ones you have there.

As above the VY booster won't bolt up without mods to the firewall and pedal setup. A great upgrade instead is to adapt a VT-VY master cylinder to fit the VS booster. Guide here, I've done this a number of times: https://www.calaisturbo.com.au/showthread.php?t=134762

Especially handy if you're putting VT calipers on as you'll end up with more pedal play - the VS master isn't really suited to a bigger caliper with more fluid displacement

I have VT fronts, VT mc and VT booster in my VP. I needed to modify the bracket and booster but not the firewall. Mod to the booster is just to weld up the hole in the push rod and re-drill it a little closer to the booster. The bracket is modded as described by Marco. He also offers them for sale. It's a good upgrade. Much lighter pedal needed with a good progressive feel and much better stopping power. I only have the 298mm VT rotors under 15" CSA rims. The rotors are straight slotted and not sure I would bother with them again as they whir under high speed braking. Marco reckons curved slotted are better in that regard.
