It all comes down to the weight of your car.
I run GTR Brembos all round.
2 piece alloy hat DBA5000 rotors up front and slotted rotors down back.
We use Ferodo DS3000 pads all round and Castrol R synthetic fluid with Goodrich stainless steel braid lines all round.
Master cyl is matching GTR.
No booster is used.
Pedal ratio altered from 4:1 to 6:1.
My car weighs around 1250 with me or fuel.
I couldn't ask for better brakes. Circuit sprints/Targa Tasmania, street sprints, whatever, its a fantacstic combo.
I use them hard, very hard, but the rotor's peak temperature is perfect, right within the Orange range on the heat paint on the rotor.
I drag the brakes a little on the warmup lap to obtain good temps, but also find it stops just fine when I'm not given the opportunity, say, a street sprint or hillclimb.
Highly recommended if your car is around that weight.
