I was just told that because of the legend rotors being thicker than stock ITR, I need a longer bolt and washer in order to bolt up the NSX calipers to a stock ITR brake setup (pads and rotors).

Did any of you guys use nsx calipers with stock itr rotors? I don't plan on getting legend rotors till after these stock itr warp at the track.

here's the mass thread on nsx calipers.

Everyone is running Legend GS rotors but I don't see any info pertaining to keeping the stock itr rotors. Maybe on me

Thats because they are the same..........

 

I believe the Legend GS rotors are thicker in diameter.

Stock ITR = 32mm
Legend GS = 38mm

 

No. 23mm, 23mm, and 28mm. Stoptech rotors were 25mm.

*sigh*

NOT true. ITR rotors are 23mm thick, and Legend GS/NSX rotors are 28mm thick.

 

Yes my mistake.

I meant 23 vs 28. Thanks.

So what do I have to do in order to make these "bolt on" to stock ITR rotors?

There's even pictures.

 

yes but that is for the Legend GS rotors.

I am looking for info on how to bolt these onto stock ITR 23mm rotors.

RTFT!!!!!

Rodney even took pictures and detailed description of his setup!

 

I just read through it again and rodney seems to have some good info but no specifics.

Just posted that he is using stock itr everything with the nsx NA1 calipers.

But there is a problem that you loose 5mm of pad life but gives you more clearance.

I just want this setup to fix exactly like stock until I pick up the GS rotors.

Thats exactly what you want, isnt it?

You should throw away the pads at 5mm left anyways. Besides what you lose in the use of pad thickness, you will gain back in evenly worn pads at the track. Its a wash in pad life.

True that. This will suffice till they warp at the track.

How's this to bake your noodle... rotors dont "warp"....

In fact we had this same problem, commonly diagnosed as "warped" rotors... was just a material problem. Cleared up after 4 days of street driving.

 

Was this using the same pads as the ones that were tracked?

How were the rotors when they were hot at the track?

I have heard of this "ghost" warping...

Yes. We didnt even take the wheels off.

Thats where the problem showed up. Got worse all day sunday. Then went away after some street driving.

 

I have NSX calipers on my ITR..93 spec, i just bolted them up and went on my way...am i not suppose to do this?

 

quite a difference there

 

i'm running the legend calipers..but it didn't come w/the legend brackets..so i have to use the stock itr brackets...thus running ITR rotors.
i forgot who, but someone here on HT was nice enough to send me their old pads for free. i took it to a machine shop and had them grind it down to exactly 5mm thick (to counter the 5mm difference). rubbed the grease all over it..and put it inbetween the caliper piston and the actual (new) brake pad. works like a charm.


sidenote: does anyone know if the stock ITR brackets can handle the larger Legend rotors? i was told it wouldn't

 

This sounds like a bad idea. A very bad idea in fact. I would not recommend doing this. If you've ever seen brake failures or things come apart at high speed....

 

thanks for the input RJ!
i agree i thought it was a bad idea..but honestly it's been holding fine, even after a track day... but a friend of mine who runs a lot of track days (and also a mechanic) w/the same setup. i figure if it's fine for him, it would definitely be fine for me.
i wouldn't know how it would fall apart if it's secured in the caliper and is the exact same shape/material as the backing of a brake pad?
