Alright, I have seen these on Ebay as well but I don't know much about rotors. I am not going to ever take my car to a track. I basically think that these look much nicer than the original rotors. Is it truely likely they could crack under normal driving?

dude, you can drill the rotors you have on the car now for less than that, like, free.
you can't really say what they're gonna do (they might just break in normal use, but maybe they'd be just enough), but what's for certain is that they're plenty worse than the stock rotors the way they are.

As they wear down, they will be apt to crack, even on the street. How soon and how much depends on a whole lot of variables (like how hard you are on the brakes, your average driving situations, the pads you use, how well the rotors were drilled, the quality of the rotors to begin with, etc.). It has been known for cracks to appear rather quickly on normal street driving on poorly done rotors.
And I mentioned this in another thread, but you have to make sure that they used a proper pattern. If they did not use a proper pattern, and drill accurately, the pads and rotors will wear unevenly, braking performance will suffer significantly, groves will appear, and you will be replacing pads and rotors very quickly.

Those black rotors sure would look nice on my black 8... I bought some cross drilled and slotted brembo blanks for $100 for 2 and drove them for 80K without issues on my last car. I think thats the route I'll go when its time to replace my pads.

What would be a "smart" purchase for a drilled and slotted rotor, not being used on a track. I have seen posts about Rotora (I think the offer a slotted type only, not sure though) Also what can I expect to pay for a set of quality rotors?

I was over at the Racing Beat Open House and they had Power Slot Brakes over there. They have a good slotted, vented brake rotor (had dimples in it for the faux crossdrilled look). They have it in their brochure, and we had talked about it with them. You have to be careful about this as these are what are stopping your car. Unless it is Brembo, Baer, etc. (especially from some company I have never heard of, on Ebay) you really have to question whether they are up to spec, will they crack at the first sign under hard driving. What specs are they manufactured under ?

I gots 'em......
I bit.
The drilled (special order - drilled only, no slots) rotors arrived recently, and I am quite pleased with the initial quality.
They are 'Centric' brand, not one of the Brembo/StopTech echelon brands, but not exactly no-name either.
The rotor surface looks good, the drilling and balancing holes are nicely finished, the mount surfaces are machined smooth and the vanes inside are clear and free of 'flashing'. Weight is 18.5 lbs.
I am quite happy with the deal, the price was great, and I will only be using these for 'Bling & Pimpin' purposes
, with my newly polished-up alloys. Track days will be back to Mazda stock.
Will keep you posted as to how they hold up long term.

I found this on a news group:
He wasn't the only one who mentioned how easily the drilled rotors tend to crack. They do look cool though.
Cross-drilled rotors can be a problem: they crack _extremely_
easily in hard use. Originally they were introduced for
non-endurance racing as a single-use solution when maximum
braking power was required, combined to (marginal) weight
savings of removing material from the rotor.
They're _not_ suitable for a street-driven weekend racer as
the point of all is to keep mileage to an absolute minimum
and have only poser-value because of their looks.
Slotted rotors are something else, ie. quite good for track
use and quite allright on the street as well if you can put
up with fairly quick pad wear.
Still, the way to go is a pair of flat, vented rotors with
good racing pads (Ferodo, AP, AXXIS etc.) - I've tried just
about anything from stock cross-drilled rotors to current
flat Brembo rotors on my GTR and so far I've liked the
combination of non-slotted, non-cross-drilled NISMO rotors
and AXXIS racing pads the best. A 6-pot AP brake update
is well overdue (the car is under-braked with the current
setup) and I'll probably get to that this spring.
Using standard, vented 14.4" rotors that come with the kit,
that is.

Delicate.....
I agree completely, they can be quite delicate, even hazardous, but don't forget the immortal line - "they have poser-value only" !!
Poser value........mmmmm!
The seller was the same as that link, 'R1 Concepts'.

either way great find for the price.
i have had a bad experience with some brembo cross drilled in my tII
but at that time i abused the car regulary so i may have something to blame.
anyone got the slotted ?
or cross/slotted ?
