The rears are going to be slightly more expensive than the front rotors due to the additional cost in the aluminum hat. The hat is machined from a massive chunk of billet aluminum, that is expensive from a material standpoint. The iron section is also not a standard dimension, this also significantly increased the manufacturing cost having to have the irons custom made.

Just to confirm. These will be listed for $728 regular price. But we will list these on special for an initial offering at $648 plus shipping. Again, to also confirm, this is for the PAIR of rear rotors. We have a limited number of sets available at this time.

Amazing price Dustin

But even more importantly, which way do they spin?!

The internal vane direction dictates the direction of rotation...which is what I think someone mentioned previously.

If you plan on installing brake ducts that are mounted close to the hub, you want the vanes to slant towards the rear of the car. Inside (hub edge) leading. This will allow the vane to "scoop" the air and spin it out through the middle of the disc. \\\\

If you do not plan on installing any brake ducting, then it really does not matter. However, a 19" or larger wheel will have additional clearance between the wheel's barrel and the rotor itself. These will allow air to be scooped and pulled into cool the hub/wheel bearing....in theory. ////

The vanes are designed to scoop air and force it through the rotor. The rotor will perform this action, regardless of which direction you choose. However, if you do install brake ducts in conjunction with the rotors and install the rotors in the wrong orientation, the ducting will be work to its full potential.

I hope I have answered your question.

Yes. I have never seen this suggested before, I think that would be an interesting test with some equipment to measure temps in both orientations. I will probably stick with the industry convention on orientation regardless of ducting or not. Thanks for the reply.

Please let me know if I still need to change...Is it because of the slotted directions? Thanks for the heads up Depointfive0..

It's the internal vanes that determine the proper installation direction. The direction of the slots on the rotor surfaces is irrelevant.

Z1 posted on this earlier in the thread and they recommend that the outer vanes point to the rotor....I switched mine after being told this by SSFirehawk.

Yeah, that's a great price!

I forced my credit card info on John without knowing the price, lol
I'm very excited to get them. I might "be sick" when they come in...

If we're using "crisis" in the way the British use the word, then yes

I already had a crisis in my pants when I saw that these were so close to being up for sale.

If we're talking about at home... I've genuinely had too many, lol. "Sick" is easier to pawn off at this point

Z1, will these be available with j hook design?

If so, I'm ready for front and rear sets.

I highly doubt it. I don't think Z1 makes any J-hooks at all...
I believe that's an AP-Racing thing that Stillen does too because they are the AP-Racing sellers as well as work with them directly to make products for consumer cars
