G'day guys, beel lurking on the forum for a few years now.
Just thought i would add my experiences to the KSport discussion.
I got the first fit of Ksport 8 pot fronts AND 4 pot rears on a supercharged V6 Mitsubishi.
In summary found Ksport and AB Motorsport to be very reasonable to deal with.
They were the only company interested in fabricating a front AND rear setup for my car.
I could have fronts in any shape or form that I wanted in a few brands , but only KSport agreed to make rears as well..
(the rear handrake drum assembly is the show stopper for most brands)
Fortunately I had a full rear axle off a wreck for them to use as a mock up for the prototype.
They picked it up from me in Geelong and freighted it to Sydney...at their expense....both ways.
They returned it two months later, complete with a full 8 piston front / 4 piston rear kit which includes high quality braided lines etc....instructions, washers,spacers,etc etc etc
I was impressed with the quality of the kit and still am 20,000k's later.
But...It's for a street car with ocassional private road use...but it is a 13.xx second supercharged vehicle running 12 psi, so it does frequently stop hard.
Around Geelong and melbourne i often saw obviously very capable cars with great looking Brembos at the front and silly looking hand red painted rear calipers.
With Ksport I have four high performance brakes, that stop like a mountain goat at the edge of a cliff.
About the only criticism I can make, and it is a trivial one, is that the installation manual is a poor English translation.
"Install bolt XYZ very tight, do not" You get the idea.....LOL
I say they are great value for money and perform well.

Here's a couple of pics of the drivers side.
