Hey, I have an NA import Qs S14 which is 4stud. I assumed it has s13 rear brakes but it doesnt, its cable to caliper not drum for handbrake and s13 disks, calipers and pads are bigger. My rear pads are down to metal so I want new disks and pads, don't want to swap out for different brakes yet. Where can I find some disks and pads? Euros obviouslt dont stock them does anyone know if other models will fit?
