Well being RB powered they can absolutely hammer with only a little modification
stock they're comparable in acceleration with a stock R32 I'd imagine, a little quicker than a stock import R31
but yeah there's not many stock ones left these days, most of them have a decent exhaust and intercooler stuck on them, more boost, computer, injectors yadda yadda
a lot of them on the road are 13-14 second quarter cars or better these days from my experience
handling and braking..... live axle rear hurts, Australian R31s are closest in design and handle better
Braking they have 4 wheel discs as opposed to n/a VLs which are disc front and drum rear
I think the turbo ones have bigger front rotors and corvette calipers
Similar size to R31 and R32 front brake setup i'd imagine
