(N1 GTR) No these have never been fitted to a skyline before they are straight off a GT1 car.
(Scooby) There are no part numbers on the AP Racing web site as you can not buy these as they where made for the GT1 sereies cars, but they use the same pads and parts as another ap caliper, a ap 59?? some thing and they where used for one season.
Im selling them as im know getting 8 piston Brembos, i think you might be gettig me confussed with Stu that had a pair of these for sale as well for $1800!
(craked) You can't even compair these calipers to Ksport calipers, New These caliper are over $5000 and I'm not joking.
