I was looking on google at brakes for the CL9 / tsx and came across an interesting upgrade. Acura RL calipers with a machined bracket and 350z discs. Actually looked very easy to do and they were nice big callipers too, I wonder what that setup would perform like? Some photos below The caliper, looks sweet! The brackets, these are a little different to the ones from a company called fastbrakes, but you get the idea.
