Just for an idea on pricing (i've spent $2,000 on my brake system this year alone).
From www.racebrakes.com.au (with member discount)
* RB74 front pads = $175
* COMP2 rear pads = $125
* 4x Goodridge Braided front lines = $360
* 2x GTR G-Kit T-Piece = $30
* Front 4 Piston Caliper kit = $110
* Rear 2 Piston Caliper kit = $77
* Front and Rear Caliper Overhaul = $200
* 2x Caltex GP600 DOT5 Fluid = $58
* Install, bed in front and rear pads = $55
* Paint Caliper and Rotors = $65
I gotta take my car back tomorrow coz things still aren't right (possibly fault in my Master Cylinder) but after a recent trackday experience i've learnt that while its fun to go fast if u can't stop ur in big shit.
My advice if you are wanting to increase your braking performance on a budget:
* RB75 front pads
* COMP2 rear pads
* Caltex GP600 DOT5 fluid
Bendix Ultimates = ~ 90c - 380c
RB74 = 0c - 580c
You should notice a siginificant difference over the standard components and you won't get fade on normal street driving.
