Would you like me to dig up picturw\es of cracked power slot rotrs? I have bunch's ,Drilling weakens any rotor, I have pictures of cracked Porsche 959 rotors down to cross drilled civic rotors. Cross Drilled rotors do not decrease stopping distance, no one has ever been able to proves this. Cross Drilled rotors do improve pedal feel, but improved pedal fell does not equal improved stopping distance.
If you took your car with brand new autozone Blanks pads and fluid; measured the stopping distance it would be the same or less than your car with crossdilled rotors with the same pads and new fluid. Read these pages http://www.stoptech.com/technical/ There is a lot of great information on brakes there, Willwod even says in the liturature that the cross drill the rotor for looks not to improve stopping distance... I have never seen any one truly fade brakes driving on the street with good fluid, if you are then you are druving your crazier on the the street than any one. With good fluid and good pads and new oem replacement rotors my stopping power of the del sol is awesome. But what do I know I only drive on Road Course for 15 to 20 min sessions where I am constaly brakeing from 110 to 45 mph for 10 to 20 laps... and I have yet to fade my stock brakes (with better pads and Dot 5.1 fluid)
