Brembo Brakes

Hey Guys,
Just regarding brakes.The stock front brake calipers on my R1 has six pistons currently..i'm considering changing to brembo brake calipers and know they only have 4 pistons.. the question is, is it worth really spending the money on brembo brakes??.. are they over rated and should i just invest in really good pads like endless pads..Is adding brembo just a bling factor or will i really feel a great improvement in my braking...Lastly, do we know of importers, suppliers and retailers of brembo in aus..tried looking but hard to find..thanks
