The kit actually comes from Greg Vogel from G-Spec in the U.S.
I can't remember how much it was, as I got it last August, but everything bolts staight on to the original mounting points.
You have to remove and discard the back plate, as it is too small, but the discs bolt on (they come drilled to 4 stud already), the calipers bolt onto the same place, and both the handbrakes cable and stainless brake lines fit straight on as well.
As for the finished article...
I have just a few things left to do, including fitting the heavy duty driveshafts, fit the coilovers and fit the front, lower wishbone PU bushing.
Give me a couple of weeks, and it will be done.
Cheers
Dave
