I guess the question is what do you mean by best? Do you mean provides the best stopping power, or is the best bang for your buck, or will clear a 15 inch rim? If you are looking for best, you would probably be looking at something like a Baer 13" rotor kit with 6 piston calipers, if you are looking at budget contacting someone like Dr. Diff may be the best route. For me I am going to be piecing my front together, and ordering a Dr. Diff rear kit as I want to maintain my 15 inch rims, but want the stopping power of hydraboost and viper front calipers.
