Z1 2-Piece Rear Rotors????

edconline · 04-22-2014, 08:19 PM

Haha the RB ones are 4lbs lighter a corner than stock, but an extra pound/side is 2 whole pounds! And that price

Should have my set tomorrow. Can't wait to get them on.

Dumb question... Correct me if I'm wrong but the rears are gonna sell for $650?? Aren't they smaller than the fronts? Dunno why they'd be more expensive.

The rear rotors were more expensive when RB debuted them too, I'd imagine they cost more to produce and develop seeing as they have to retain the ebrake.

It's R&D costs as well as how much of a BITCH it is to make...

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..

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...

Z1 2 piece rotor set front & rear installed with new pads,SS lines & Moto fluid

There seemed to be some question as to the weight of the rear rotors. My bathroom scale shows a 5 lb reduction from factory to Z1.

Tip on the install. you will probably have to back off the star wheels adjuster on the emergency brake. Check the tension on the brake assembly before re mounting the tires. On the rear I used the old caliper pins as the ones Z1 sent in the kit were too long and looked silly stickin out of the caliper.

She will be getting a wheel alignment tomorrow & then brake break in.

Nice! I think the rotors are directional I'm not 100% sure but u might want to check it before doing the alignment and brake in...?

They are.

And slam1918 installed them wrong if I'm not mistaken
