Yup it's all about heat dissipation and tyre grip more so than size/brand
If you want to stop better put in better quality fluid/pads.
If you want to stop better for longer upgrade your rotors/calipers.
I have the DBA4000 Slotted Rotors, overhauled calipers, braided lines, brand new master cylinder + cusco brace and good pads/fluids and I didn't have any issues when down at Wakefield last however... I noticed that when I backed off and did some cool down laps that my brake pedal went all mushy however soon as I got back up to pace the pedal came straight back... now that I find -extremely- weird.
