I know I need some new rotors and have been looking around. All I have found are cross-drilled and/or slotted ones. At Nopionline.com I found them the cheapest at basically $85 a piece for "Powerstop" brand. Does anyone know of any rotors that are cheaper, regular or cross-drilled/slotted. Thanks.

I too would like to know. I need to find some rotors for a decent price before I can do my 5 lug conversion.

Check to see if brembo makes some for the RX-7. They should make OEM replacment blank rotors for the FC....

Looked at brembo and didn't find anything.

I've heard of people ordering (I think) the powerslot and having them arrive in brembo boxes. It might have been a different brand tho

So is $85 a piece the best I can do for any rotors?

IMO unless you like replacing rotors I would not recommend cross drilled rotors for the street. They are much more oriented towards track racing and replacement every season. Cracking and/or shattering are common when driving hard and exposed to the elements such a snow or rain. Things that for the most part they are not exposed too on a track.

However slotted or dimpled rotors are fine for street use.

Expect to spend around $120 a rotor for good slotted or dimpled rotors.

Hey Ice, do you know where I could get regular rotors? If I am spending close to $100/rotor I will get drilled or slotted ones but if I can spend under $200 for all 4 I'll prolly get regular ones.

My local Napa auto parts store ususally has the 5 lug front rotors for about $60 USD each, and rear 5 lug for $55. I would think that some of the others like Kragen or Pep boys should be able to get them as well as they are all made by Bendix.

If I get rotors on-line or shipped to me, I will also get them turned before I install them. I found that if they have been shipped and dropped once or twice that they tend to warp within 1000 miles.

But if they get turned first then they don't seem to warp as easily.

The more material, the better the heat retention/absorption a rotor has. So any time you drill, slot, or turn a rotor, less energy can be absorbed and then dissipated.

Cross/Slotted rotors are used primarily to prevent gas build up as the pads wear and give the gas somewhere to go (instead of floating on the surface of the rotor and keeping the pad from fully contacting the rotor).. Modern day pads don't produce nearly the gasses that they used to.

I'm running the Non OEM rotors from mazdatrix, going out to inspect them now, but I don't expect any problems from Wednesday's test day.

IOW, dont' spend a lot of money on slotted/crossdrilled rotors unless you want that look.. Nothing wrong with that, but if you think they'll work significantly better, they won't.
