Thanks!
I got the brake calipers, bolts, etc from Holden Parts, and the rotors & pads from GSLRallySport
I did explore getting the brakes painted, but if I was going to do it at all I would do it properly which means taking them apart, getting them powdercoated, then rebuilding them! Sorta not worth the time/money, and I can live with silver!
On another note, got a 3.7 diff put in last week, after a day or so of getting used to it, I love it! Accelerates much faster, and much more drivable in all gears! I will post the difference in quarter mile times when I get a chance to retest!
