please please look into the vr4 rotors b/c i have heard that these rotors will fit under some 16" wheels. and that would be a big plus for me

chmercer · 10-04-2006, 08:56 PM

vr4 rotors bust off at the hub, bad stuff.

You really think the rotor will move after you torque down the lugnuts??

I've run the cobra rotors without the lug spacers (with the "slop"), autocrossed it for a full season, done track days, etc,. I assure you, the rotor isn't moving back and forth.

Only if your lug nuts were torqued to like 2 ft-lbs, the rotors would only move in one direction and stay there. Only when you go in reverse and hit the brakes, would the rotors rotate in the other direction relative to the wheel.
But if your lug nuts are at 2 ft-lbs at anytime, you should sell your car and go buy a tricycle.

I'm running the cobras with Z33 wheels (17"), there's plenty of clearance left all around the brakes.

timtiminy · 10-05-2006, 12:21 AM

Slidin240Wayz: I doubt 3-4in extensions would be necessary, probably 1in would do it maybe 2 at the most.plus you wouldnt want all that extra line risking the possablity of it getting caught up on anything.

okay so are vr4 rotors a bad way to go? seems to be a possibilty for 16in rim guys...would only be good for z32 calipers and they will have to be offset like the R33 brackets are in the pictures.

slideways2004 · 10-05-2006, 07:02 AM

what else i was thinking about the cobra rotors were get them redrilled with the right size hole. they'll be the same bolt pattern just with the smaller hole. then it will look like a 10 hole universal wheel. i think this combined with the hubcentric ring would make it really stable

chmercer · 10-05-2006, 11:01 AM

the fact that the holes are the wrong size dosent matter at all as long as you have a hub ring. as long as the thing is centered itll be fine. now if you tried to run them with no lug spacers and no hub spacers, it would probably shake like crazy.

wilfonzo · 10-05-2006, 11:41 AM

those "r1concept" VR4 rotors are the same price as the autozone "duralast" cobra rotors... VR4's = more bang for the buck

chmercer · 10-05-2006, 11:51 AM

as i already said, vr4 rotors are a shitty design that is prone to breakage, like everything mitsubishi makes. I hardly see how they are more bang for the buck considering they are smaller than cobra rotors. also the cobra rotors wont kill you.

hella "bang for your buck".

Mirage · 10-05-2006, 12:44 PM

good thing you gave the whole story, wouldn't want sheep to be mislead or anything

http://www.team3s.com/FAQbrokenrotor.htm

3/s owners know powerslots are shitty for the car, the owner himself claimed the porterfield was below spec on rotor thickness, a cryo treated rotor, which makes metal brittle, after 3 track days, one guys occurance, on non stock calipers. I cant think of any other occurances the 2 years I read 3si

-former '93 vr4 owner here

i'm up for any form of ecr33 brackets, be it track or cobra, but i'd lean towards track if it was one or the other.

wilfonzo · 10-05-2006, 12:48 PM

point made, i guess cobras are the better buy then

or those porsche calipers are just hella strong.. j/k

dude, shut up. vr4 rotors are shit. there is like a million instances of them breaking off at the hat. that was just the first thing to show up when i searched broken vr4 rotors. im not going to waste my time googling up a heap of pictures for you.

timtiminy · 10-17-2006, 03:25 PM

what does everyone want??

Slidin240Wayz · 10-17-2006, 04:52 PM

Stick with the good stuff, z33.

Carlos

ixfxi · 10-17-2006, 05:19 PM

i have the track model z33 brakes.

they are god fucking heavy. not sure if i am going to keep them. both the calipers and rotors weigh a ton. it be more cost effective just getting a nice quality wilwood setup.

toledo240 · 10-19-2006, 02:24 PM

hey guys im running the z32 rotors right now on 4 lug setup, If i take interested to go 13" rotors would i might want to consider the upgrade to 5-lug??? 13" is a bit bigger, yet the 4 lug is space pretty far out at 114.3 so i just want to know your opinons if it could withstand that size of rotor?

turtl631 · 10-19-2006, 06:29 PM

Do the brackets for Z32 calipers with Cobra rotors, you'd be filling a niche that is currently vacant for a really affordable big brake setup. All the cheapasses who can't afford expensive Z33 rotors and R33 calipers, not to mention Brembo, Wilwood, etc. BBK setups will go for it. Myself included.

Vlasic · 11-20-2006, 07:05 PM

please, Please, PLEASE make some brackets for cobra rotors. Ill buy thoes brackets in a second if you made them. Brackets for Z33 rotors are already available.

For all of you who are concerned about using cobra rotors because of having to use a hubcentric ring and the larger lug holes; Just go look at the Maxima guys. When they upgrade to z32 calibers they use the cobra rotors and no one has ever had any problems of complaints about them. There is nothing wrong with using hubcentric rings, neither is having a rotor with larger lug stud holes. One the wheel is torqued down, the rotor isnt going anywhere.

CylonFrakker · 11-20-2006, 08:46 PM

has anyone considered lexus 1995-2000 LS400 rotors they are like 12.6" and are 5x114.3 the stud bore should be about the same. Also consider the Supra TT rotors which are just about 12.71" and can be had cheap from RockAuto.com $16 bucks a piece. Good luck and let us know. Migh also consider an adapter for Supra TT calipers or LS400 calipers they have larger pistons and are pretty freaking good. I would also recommend the LS400 calipers from 1995-2000 they are the best to use because they are alumium.

turtl631 · 12-13-2006, 05:43 PM

This guy seems to have vanished, which sucks because I was looking forward to having some brackets to use the $25 rockauto.com Cobra blank rotors. What were those pics he posted; did he actually make some prototypes?

Vlasic · 12-14-2006, 02:33 AM

Ya i was looking forward to them too. I was gonna go with the Z33 rotors, but the SPL bracket is so expensive.

timtiminy · 12-16-2006, 08:22 AM

I still have everything in the works guys. sorry about not keeping up with this thread. it has been a hassle trying to find someone to do small machining runs and still be able to keep the cost down the problem i am running into is that noone wants to do 50 pieces they want to do 5000 pieces and when i do find someone that will do a small run they want a ridiculous amount of money per piece, so that in turn will increase the cost to the consumer/you guys and i dont want to do that. My whole reasoning for making these is to offer a great product for a great price. hopefully things will start to pull through. I still have to talk to someone i know who machines so at the very least he can make a few brackets for those of you who are serious about buying them in the mean time till i get a good size run made. I'll try my best to keep all of you updated.
-Tim

turtl631 · 12-16-2006, 03:08 PM

Cool, thanks for the update. I appreciate trying to keep the price down, because frankly, I'm not gonna buy these if they're close in price to the SPL ones.

timtiminy · 05-21-2007, 12:46 PM

okay well i finally got some brackets cut. waiting on the hubrings. hopefully a week or so and i'll have the kits ready. here is a pic of the 2 brackets. sorry it has been forever....

timtiminy · 05-21-2007, 12:51 PM

I like the fitment of the z32 caliper with the bracket and cobra rotor. there is practically no pad overhang. the r33 bracket is a different story....there is about 5mm of pad overhang so i redrew the part and hopefully i can get them remade, as i am not happy with the fitment right now. I'll post pics of the z32 caliper mounted with the bracket and cobra rotor once i get my camera working again...dont know what happened?looks like the shutter is stuck closed...??

babowc · 05-21-2007, 01:51 PM

nice..
put medown for a cobra bracket

MyLevinGTZ · 05-21-2007, 07:23 PM

i too am interested in your setup. I have R33 brakes and hubs all around so i'd be interested in the bracket for the cobra (or what ever) as long as it's for the R33 caliper. hardware included. i can source rotors unless you can get em cheap, no biggie.

please email me if you get this sorted out because i've got a terrible habit of not tracking these threads.....

[email protected]

thanks again, good job on doing all this work too.

timtiminy · 05-22-2007, 11:06 AM

okay i got the camera working. the shutter was stuck closed or something...I took the thing apart and opened it up, put it back together and it seems to work...dont know if i jacked something up that i dont know about though...I'm not a digital device repair man...
Here are pictures: first one is the z32 caliper mounted on the bracket and the cobra rotor on the hub. second is showing the pad overhang on the z32 pad with the cobra rotor. its very minimal only 1mm at the most.

turtl631 · 05-27-2007, 10:52 PM

Lookin' good. I'm down for a set of Z32 caliper/Cobra rotor brackets and hubrings as long as the price hasn't gone way up. I have 17" Z33 wheels now for daily driving so I don't have to worry about wheel clearance, hooray. Email is rrozyckATgmailDOTcom, shoot me an email when they're done and you've got a customer.

harleys · 05-28-2007, 12:33 AM

i'm also interested. put me on the top of the list.

Lordrandall · 05-28-2007, 04:52 PM

timtiminy - I don't know if it is too late, but I have a friend who makes the Cobra brake hub rings for Maximas. They would fit 240's as well.

If you've already made the rings, no big deal.

What's the latest with brakes that will fit under 16" wheels? I have the z32 brakes already and some r32 GTR wheels.

Thanks!
