I have respect for your track experience and have stated that I agree with your claim of braking improvement on the track. I just don't agree that it transfers to the street to the inflated degree of your original claim.

All this talk of track grade pads and rotors when the OP simply wanted a street pad/rotor set. Lol.
The heat dissipating benefits of a 2 piece rotor and frictional operating range of trackable pad would not be perceivable (nor suitable in terms of pad compound) on the street.

^Haha. I fear I started something. I kind of saw it coming after reading all of the other threads pertaining to this topic. My bad.
I don't claim to know much about brake components. In fact, brakes are the weakest part of my technical knowledge. I tried to make a humble approach for that reason. I wouldn't replace the stock set up if I didn't already need new rotors. Since I do, I was just wondering if this set was a waste of money, in the opinion of our well-knowledged community, or if I should just stick with the stock set up.
One thing can be said...we are a passionate bunch. This speaks volumes for our love of our cars. Nothing wrong with that. Just remember, at the end of the day, we're all missing pistons, and that's bad ***!

For street use rotors are rotors, and unless you need to upgrade to curved vane or 2-piece rotors, find the least expensive OEM blank you can and go with it. Rotors are a wear item. Try http://zeckhausenracing.com/ for quality OEM blanks by Centric rotor. For a more expensive curved vane upgrade try http://www.racingbrake.com/v/main/ve...asp?model=RX-8

Believe me, I'm listening to what you have to say, but from my vehicle engineer perspective, it's a little hard to believe a rotor change could halve the stopping distance of a car. Notice I'm trying to brainstorm reasons; from a logical standpoint your claims don't add up to simply the rotor change. Acceleration, or deceleration in this case, is the square of force and so to halve the stopping distance would require FOUR times the stopping force. A simple rotor change would leave the lever arm of the braking system the same and so clamping force should not change. The only way I can see it happening is the superior thermal properties of the two-piece eliminating fade, but that is a lot of heatsoak for the standard rotor to go through. You might have claimed to see it first hand, but remember this is the internet, and more than that, as an engineer I really want to know the REASON WHY. I'm not willing to simply accept X comments at face value unless I find the logic behind it, and I'm trying hard at the moment to do so.
maybe we all missed the variable where he used those components on a rx-8 with a weight thats reduced in 1/2
that sounds logical enough to me...

I see where Lion is coming from, trying to look at it from an engineers perspective but instead of trying to analyze things I like to actually go out and physically do things. People fail realize that slotted rotors actually help your pads grip more because they literally cut away at the pad. Also, our cars weigh a pretty good deal less than stock too, just over 2600lbs.
I do realize that 90% of the people on this forum will never experience what this car can actually do on a track at full race speed...I was just sharing my experience of drilled/slotted rotors from a race speed perspective.
