apart from wanting ventilated front rotors instead of the standard "solid" ones....
I know an airplane engineer in Australia fitted ventilated discs from a Ford Sierra (afair) on his Bagheera (which he btw converted to RHD) - and the pictures I saw were very impressive.
However nice that could be, I think you would only really need them if you took your car for track-days ... Having driven very enthusiastically around a track for 5-6 laps, saw my brakes fade - but then a cool-down lap restored order.
But I doubt you'd ever need this much stopping power on normal roads - but then again, people drive like maniacs in your part of the country,. I've heard :-)
My car has EBC GreenStuff pads, and that was a revelation - a subjective, rough guess says 25% more stopping power, which was completely unexpected. I only got the GreenStuff ones on as I heard they didn't produce the same black dust as normal pads, and I dismissed the claims about better braking power as the same marketing rubbish as fuel additives.
