Yup, the J-Hook is advertised as being a 'patented AP Racing design'.

As mentioned above, the J-hook design is a patented design by AP Racing.

We have some other ideas bouncing around, but nothing even close to being put into motion at the present time. These rotors have been a few years in the making as is. We are in no hurry to make any additional revisions just yet.

follow up
 
I sent pix of the new rotor install to Z1. Jon from Z1 came back to me via email later in the day and said swap the fronts. Shannah also sent a follow up and said Z1 will label the rotors which should avoid any future questions. I swapped rotors this evening, test drove, did some 80 to 20 aggressive braking & put her to bed for the night.

Installed and ready for AutoX tomorrow. :tup:

Shadezz 05-13-2014 01:03 PM
Thanks John...I'll get you some pics of the install and finished look!!! (Side note..the badge didn't come with 3M on the back, but I'll get some and just cut a custom piece for it.)

Just put mine on as well as some z1 extended stud spacers 20mm

I am hearing the rear brakes rub on the disk and the car does not move as freely as before. Something is dragging...Im thinking the ebrake shoes

Any tips or help on how to fix this?

I wouldn't drive like that. Go adjust the boot adjustment thing. It's on the top of the drum, you can access it through the hole in the rotor, and flip it up

Not driving it at all. I have adjusted the boot thing about 5 times already. I have tried just about every click setting and it still makes noise. Seems to only be the drivers side

you can hear it with the rear jacked up and spinning the wheel by hand...something is dragging

something else I found interesting. adjusting the star all the way up or all the way down and it will stop the wheel from moving completely.

Ohhhhhhhhhh, ok.
Is there resistance?

hard to tell by hand. but in reverse when I pull out of my garage I normally roll right out and now it wont move without giving it a little gas. its a very minor sound/resistance

Super Werty 06-01-2014 06:19 PM
adjusted it again and went for a trip around my hood and I dont feel any rolling resistance backing out, but the noise is still there. Just sounds like a pad touching the disk. You can only hear it with windows down at speeds below 10mph

Im hoping its not the shoes rubbing a hole through the hat from the inside out

slam1918 06-01-2014 07:54 PM
check the thin backing plate on the front's. You may have bent it slightly and it's rubbing on the rotor.
Take the rear tires off and rotate the disk. Recheck the ebrake shoe & make sure all is in good order.

Super Werty 06-01-2014 08:06 PM
Thin backing plates on the front of what? can you elaborate please

slam1918 06-02-2014 06:16 AM
behind the front rotors there is a thin metal plate that keeps dirt from flying onto the rotor. If you remove a front tire you can either feel & or see it behind the rotor. I replaced my front struts at the same time and accidentally bent the plate so it was making contact with the rotor and made noise at low speed.

The dust shield? No I didnt bend those. There is no noise coming from the front rotors. It's all in the rear. The ebrake shoes are rubbing slightly on the disk. Im going to take it apart tonight and try to solve this.

Super Werty 06-02-2014 06:05 PM
Ok I pulled everything off expecting to see wear marks on the inside of the disk where the ebrake shoes grab and....nothing. Looked perfect inside there. My adjustments on the star were perfect on both sides. No visible drag or wear marks anywhere on the disks at all.

Could this just be the pads sound on a rough new disk? I just have never heard this noise before on new disks. If I go and hand turn my front wheels they are completely silent.

This is what it sounds like while driving...

Mine made a similar noise before I bedded the carbo tech's in but the posi quiets did not. I would just try to bed them in if there is no sign of wear.

Thats what I'm thinking. Just went out and did a few hard stops. Seems the noise is starting to quiet down with each stop.

Shadezz 06-03-2014 01:45 PM
Thanks Z1!! Shes stops on a dime now!! I'm having some high res shots taken this Friday..Can't wait for you guys to see them!!

You installed them backwards!

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.
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.

Super Werty 06-03-2014 08:18 PM
Just flip them.. it only takes 30 min

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.

Agree..i'll get them switched tonight. Thanks for the heads up guys!!:ugh2:

here we go again.....Z1 said they would mark the rotors L & R....my thread show pic's of wrong & correct
