Im still yet to be talked out of the UAS upgrade thou... $1595 for 330mm with 4 pot HSV caliper & briaded lines. Plus the availability & price of you-beaut pads for HSV calipers is pretty damn good. No master cylinder upgrade required.
In fact most brake upgrades can be done with just having the master cylinder & bias splitter re-valved to suit.
Yes they were the next best option in my opinion but since I dont live in OZ it would've worked out to 2 and a half times more by the time i got it here! '
Plus I prefer how the wilwood calipers look
That caliper looks bloody hard to clean
