Thank you Dean. Yes, the purists camp love the OEM look, as I assume you are. However, the owner wanted something a little bit more personalized, and he chose these.
Isn't the "single piston caliper rear brake" just the handbrake/parking brake? - ie it's really nothing to do with the car's normal braking system at all?? You seemed to have gotten a bit confused here... or did I miss something somewhere??
Like you mentioned Mark, it doesn't have anything to do with normal braking, but it's interesting that the setup is two types of brakes calipers and pads in the rear.
