UPRATED BRAKE KITS / AP v BREMBO

[Hotshot 5]

I would like to know the weight of the AP (CP-5200) 4 pot / 330mm slotted disc & the Brembo Grand Turismo brake kit of equivalent pot & disc size. Want to know which one is lighter.
Also understand Brembo G.T. has a 4 pot but comes in 350 or 355mm disc I am not sure.
I am looking for the lightest uprated 4 pot brake system in the market. Any suggestions please.
