Not trying to argue with you on this but....the main point of the OP posting this thread is to steer people away from spending excess money on a braking system for minimal gains if at all. I think it's been proven time and time again that good pads, and also, good rubber, will yield you much more noticeable braking results as opposed to overall rotor / pad size. BBKs do handle heat dissipation better as the increased surface area naturally would. But truly it's all about the pad material and how good your tires are, period.i just finish reading synopsis of 2006 SAE's (Society of Automotive Engineers) technical book "The Effect of Rotor Crossdrilling on Brake Performance"
it does not tells me if the drilled rotors are prone to crack vs blank rotors, but it did confirmed x drilled rotors are functional, x drilled rotors are not cosmetics. so sae's engineeer's are wrong then ?
I live in socal as well and you should NOT be boiling fluid from DD'ing. I would say there is something wrong with your brake system. The only time me or any of my canyon buddies have ever managed to straight boil brake fluid was from doing runs for nearly an hour straight at nearly the capacity of the car, this was also on dot 3 when we we're newer to the canyon scene. Now we all run racing dot 4 or 5.1, never boiled fluid since. Brake fade? Yeah, definitely... after 15 minutes on cheap pads that'll happen but we're all running better pads and blanks now and we haven't boiled and there will only be fade when we're really pushing it. For DD'ing I've never heard of or experienced anything near brake fade, hell even Napa ceramics won't get to the proper "ideal grip" temperature from normal driving.stop tech's x drilled rotors are cheaper than blanks & slots...
and if the test results are correct, even 10% temp reduction is a big deal in so cal, during summer time, just few hour of local drive will cause brake fluid reach boiling point.
i'm not sure how hot the rotors are.. but if i can reduce 500f down to 450f for everyday driving, i think it's good upgrade.
here is another test conduct by DOT, about brake system temperature.
