Mine are finally in, just never updated, working great. I have a slow fluid leak, probably from the rear break lines. They are SS lines but I don't think they are the right ends for the caliper. Something is leaking, and I haven't had time to go back and look takes about 3 weeks to get the light on in the dash.
All in all, looks much better, e break works and car looks modern. I have the doward front calipers fomr the cobra and i'll finally stop bitching about them because they are SOOO much better with pads that bite less. The Hawk HP+ were terrible and way to grabby. I've put centric ceramics all around since i'm not tracking anytime soon, and the breaks feel very modular.
This upgrade isn't really an upgrade IMO since realistically, you really really have to push the car to the limit to tax the stock rear brakes. IMO it's more for looks than anything else for me.
