So.. trying to find someone reliable/affordable to machine dogbones etc. for my V8 Supercar alcons is proving to be a bit challenging. (My calipers https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-ash4/1094662_10153125748100301_2119536866_o.jpg )
The Alcon extremes (http://www.jdl-brakes.com/alcon-adv-extreme-brake-kit-front-6-pot-o365x32-nissan-skyline-r32-r33-r34-gtr.html) appear to be a much easier upgrade as they come with all the parts ready to install.
Aside from running a smaller rotor, what are the main differences between this kit and the calipers I already own?
Brakes are for a 32 GTR track car, mainly doing sprints.
