Cross Drilled, Slotted, Both or OEM
That is the question. I need rotors and trying to figure out what i want or what i need. Would like something good for the occasional autocross, mostly street, maybe something good for spirited driving. Obviously price is a factor so something not real expensive. Please let me know what you think. Thanks.

drilling serves no purpose other than looks. if your rotors are frequently super hot the holes might actually decrease rotor life due to uneven heat. on top of that it kinda makes you look a bit like a tool. slotted is the best if you want high performance brakes. so +1 for powerslots

RacingBrake slotted for me - happy with them so far, but I don't track/AutoX. Haven't ever heard a bad thing about them though. Brice at Fluid got me a solid deal. And they look pretty good imho.

Blank or slotted is the way to go. I just got some RacingBrake slotted rotors in the mail and I will be taking my 8 to auto-x and a track day next month, so we will see how they hold up.

Blanks are fine, slotted OK, drilled just bling. The rotors aren't the weak point in the RX8 brakes. The only change you need for the track are pad and fluid ugrades. For the street the RX8 OEM brakes are excellent.

OEM rotors are very good.
Slotted, with internal curved vanes such as Racing Brake Sport, can dissipate heat a bit better (and look cooler too).
Hawk Ceramic pads really do reduce noise and dust, but the OEM pads are very good for street use.
Drilled rotors are pointless and potentially weaken the rotor structure.

you can buy the "Centric Brand" OE replacement blank rotors online for around $50 each, anything else on a street car is a waste of money and of no performance value
be careful who you call a "tool" when there's no mirror around for a reality check ....

So ever since I changed my pads/rotors, I have noticed a really interesting phenomenon.
With the OEM pads and rotors, I had a ton of brake dust, especially on the fronts. Obviously it's a bit hard to quantify, but I'd say the fronts had almost 2x as much brake dust on them as the rears, in general. This isn't a big shock, of course.
However, once I put the new pads on (Hawk Ceramic) for front and rear, and swapped the front rotors for slotted RB rotors, I've noticed not only a dramatic decrease in dust on all 4 corners, but also that my fronts are now noticeably LESS dusty than my rears. I'd say now that the fronts only have roughly 2/3 the dust of the rears, a huge change from what I previously saw.
The only difference is that the fronts have slotted rotors, while the rears do not. I cannot think of any reason that the front pads would produce any less dust than the rears, since they're the same brand and compound. But for whatever reason, my fronts are less dusty than my rears now. It seems to me like the slotted rotors would have to be a contributing factor to that, because how else could you explain it when that is the only difference?
Am I nuts?
