We run that size tire (Hankook RS3 soon to be RS4) on the race cars. Both cars are running 15x8 +25 Enkei classic wheels. Both cars have ~2 degrees of camber in the front and the fenders are rolled. One has EX knuckles and brakes, the other has regular Si knuckles with a Fastbrakes adapter, GSR caliper and Corrado G60 rotors. Good luck finding brakes that don't squeal and actually work. Both cars are turbocharged (one is a D16 the other is a B18) and make about the same power you are planning for, you'll work the hell out of the brakes if you're beating on it.
Both cars have 90-91 Si rear brakes and OEM 7/8" MC. I prefer the smaller MC for the pedal feel, but that's really your preference. Both cars have adjustable aftermarket prop valves and complete custom brake hoses, but the one with EX brakes ran a 4040 and a stock valve previously, we balanced it by testing and playing with pad combinations. Your needs may vary, our cars are usually racing up an incline so the braking needs are different than a street car or flat tracker.
