Cobra rotors with 300ZX pads...not satisfied..anyone else?
i installed the mustang cobra rotors tonite with my 300ZX calipers. I think i got some bad rotors cause it wobbles alot. Double chcked my work a few times and still couldnt figure out the wobble. Got the rotors off ebay so maybe its junk...also when i brake initally it clunks a bit....Im wondering iif the Mustang bolt pattern is different or i got wrong rotors or what...i dunno

Hmmm, maybe it is the rotors, does it only wobble when your braking?
I helped Jeff when he installed his for the first time and it went really smoothly. After the pads bedded it stops very well and is really nice. He bought his rotors from Napa.

Yea, I got Cobra brembo blanks and I do get a wobble at about 60-70 mph. My only guess is messed up the hub-centric ring when I reamed out the middle of it. Had to take a dye grinder and make the center hole bigger to fit my hub in other words; was a tight fit and I had to use a screwdriver + hammer to get it on all the way. Just make sure you have to rotors up against the lugs in the direction the brakes will drag them also. Had mine centered till I decided to panic stop from 120........the rims were tightened down big time but the rotor still shifted up against the lugs, lol. Well, if ya have anymore questions just lemme know and I'll be glad to help ya out.

The rotors probably need to get turned. I bought Brembo blanks from one of those nissanparts websites and installed them and there was a massive vibration, drove to the mechanic and he put them on the lathe and they needed to be turned. It happens unfortunately.

Update: The clunking is still there. Mostly when turning or under acceleration.
i went back to my old brake setup and its still clunking. The only other thing that i changed was the passenger side axle. Seems unlikely that it could be a defective axle but ill check it out i guess. Dunno what else it could be.

maybe....its waranty so ill change it today and see. That MT90 that leaks out after every axle change does add up tho...

You dumping and replacing all the fluid each time? Reuse the fluid if it's new. And just top it off. Just make sure to drain it into a clean container.

These guys are running [edit]COBRA[/edit] rotors, which the link has preselected.

realistically, it would have been so much easier to juss buy a brake kit and slap it on the car. what i like most is retaining the 300ZX caliper cause it says Nissan on it. That sparks alot of interest with people i meet or talk to.

KMax mentioned he had to enlarge the inner dia. of the ring. Unless he got a odd ball set there shouldn't have been a need to enlarge the inner diameter. Sure you might need a screw driver and a hammer to install the ring flush onto the hub but it's not that tight where it can't come off with the same screw driver and hammer. KMax set-up I can see why it might wobble. If I remember correct, didn't KMax go the local parts store route (he can speak for himself)
Even though I have yet to install my set-up I also went the local parts store route to keep the price at a minimum. ($30 a piece) I can't remember the brand name (throw out the box many moons ago) but I would say it was a Bendix or Wagner rotor, definately American made.
What type of rotors did you get from eBay, was if a off the wall name brand. Did the ring fit tight into the rotor before you installed it.
But now since you mentioned you put your original brake set-up back on and it's still cluncking. It may not be Cobra/Z32 related, as I'm sure you've comtemplated already. You also mentioned the rotors were hitting the wheels studs. What type of lug nuts are you using, is it the acorn type lug nut?
When you put the rings onto the hub and then the Cobra rotor onto the hub (as a test fit) sure the rotor can turn which will hit the wheels studs. The Cobra wheels studs holes are larger than the dia of the Max wheel studs. But once you install the wheel and proper lug nuts everything "should" center up. I say should because I have yet to actualy install mine. I'm also saying all this just incase someone else may not know.

hey Mike, weather is lovely over here, not as nice as Florida im sure tho. anyways, my problem with the clunking ended up being a defective axle. ive fixed it already and no more noises. The only noise i do hear now is when im moving maybe 1-2mph and i brake lightly i hear a very slight clunk from the rotors. i wonder if theres a way to center the holes for the wheel studs and if that would do anything.

[ Speaking of that, hey Matthel besides that slight clunck you're getting at 1-2mph what's your second opinion on this set-up? Also, what wheels are you using with this set-up? Are you using any spacers with the wheels? ]
The way I look at it, if this set-up didn't work for whatever reason then I'll just slap on the Z31 caliper and milled rotor and be happy. As they say "Nothing beats a failure but a try" "No harm no foul" Not only that but I'll take the valueable lesson I learned from this and know what to apply or not apply to future project cars. (I'm not giving up on my Datsun 510)
I'm also trying to see if I can source out a better 13" rotor (with out going custom) with a more friendlier hat offset that will move the calipers inward away from the wheel spokes. Doing this will increase the dollar factor which I was trying to keep at a minimum. Oh well

hey
besides that slight clunk noise im happy with the brakes. Good initial bite, stops good, 13" rotors fills up the space good. im runnin Advan Model 7s and i have a decent amount of clearance. I hear Tantrums are almost exact copies of Model7s

I don't have the "clunk" either Turbo. I wonder what's going on?
As far as a different hat offset. Sure but now you will require a not so simple relocating bracket. One of the reasons for the Cobra rotor was the 10mm more offset. This allowed him to use an approx 10mm thick bracket and still center the rotor inbetween the pads. If you want to use something with ie.. 10mm less offset, you will now need to design a 2 dimensional bracket. Since each mounting area probably has to be let's say 10mm thick, you now have to start with a 20mm piece of steel/aluminum and have it cnc machined/flame cut. Then have the holes drilled.
It would be better IMHO to find a set of lighter weight 2 rotors that have the same OD and offset of the Cobra rotors but have the hats the same lug/hub bore of a 3rd/4th gen maxima.

Since breaking in the pads and all, ive gotten a chance to test out the brakes more, pretty happy with the performance. Im looking into getting those Eraispeed 2 piece rotors. Just to clarify, the horrible clunk noise i had was actually a defective passenger axle and nothing to do with the brakes.
