Once you get better tyres the brakes dont need to work anywhere near as hard as you can carry more corner speed,
Get some QFM Comp 9 Pads, for track days, at $190 for the fronts they are hard to beat price v performance, and some very good brake fluid (I use Motul RBF600 race bike fluid) and maybe have a look at the UAS air deflectors. and cut away the factory dust shrouds round the rotors.
As Matty Said, learn to drive the shit outta the car before adding power,
Ill be running matts Big f**k Off turbo...but at like 7psi untill I get a handle on the car.
With 235rwks and good tyres you WILL go sub 1:10s in a 33 gtst
