Sorry if this is in thw wrong forum. I tried the EG/EG but they suggested I tried here since many of you have done it on the ITR.


I'm trying to put NSX brake calipers on my EK hatch. I know many people on this forum had done it on their EG/EK and Integras.
This is my problem...
The caliper will bolt up to the knuckle, no problem here.
And the rotors (I'm using the 11.1" inch NSX rotors, redrilled for 4x100) will fit on the hub, no problem here.
But When I try to install the caliper on to the knuckle with the rotors on the hub it does not fit It semms that the rotor is too big?? Any ideas? I took some pic to illustrate the problem.


I don't see why it wont't fit?



calipers will fit with out the rotors.




the rotor is 11.1" which is what everyone is using.

 

WOW! Are you usin early calipers w/later rotors? Later NSX has larger ones. Maybe the reach on the EG knuckle is shorter then SI, GSR, Type R etc...
I just measured my rotors and they are also the 11". You may need to change out the knuckle. I've never swaped NSX to EG before but, I do know that the certain high fuel economy EG, EKs use very small front brakes. These knuckles do have a diffrent part #, maybe this is why. Just an idea...good luck

mikehonda: who likes the NSX brakes

 

Not positive but I believe it only works with integra knuckles. Can someone confirm this?

 

will only work with " Integra sized " 4 lug

non ITR
99-00 Si
and some others, not sure what other cars came with same size brakes

 

also, why NSX rotors?

you should be using redrilled prelude rotors

And at the very least removing the dust shields.

lol

 

The NSX calipers are a direct bolt on to an ITR using a Legend GS rotor. (and a 2mm washer)

The factory brake rotor stock for your car was I beleive 9.1"

You will have to either machine a bracket or swap front knuckles.

Contact Brian at Fastbrakes http://www.fastbrakes.com I am sure he can help

actually, the nsx cailper is a direct bolt on to the itr knuckle setup case closed. no need for anything else.

agreed.

 

I think the problem is with the rotors, not the calipers. I gave Willard a set of NA1 (NSX) rotors to play with and he said the offset was really weird.

To my knowledge, the only person who got NSX <U>rotors</U> to work is Bruno (Darkteg); here is his thread (maybe it might help):

https://honda-tech.com/zerothread?id=874351&page=2

now the first thing that pops out is the 14mm difference between the NSX bracket and the hub bracket. i need to fabricate a stainless steel 14mm washer for each bolt.

second, each of the bracket bolts need to be longer (at least 38mm)

 

Try using a redrilled prelude VTEC rotor or a Accord V6 rotor, both of which are 10.6".

 

You guys should look in this thread Marcus (MrHeelToe) got one of his suppliers
to have Legend rotor's drilled to 4x100 not redrilled.

I know this doesn't directly correlate to you R owners but I figure it may help
someone.

Autozone $23 rotors + high temp paint, if you have to.

 

yeah yeah , rub it in
that rotor is not an option for me

prelude rotor, redrilled $60
replacement rotor for my two piece $90
these other rotors from heel toe $124....yikes

 

you need knuckles from a abs model car.

OT:so if i bought nsx calipers right now to replace my stock ones..it would bolt on my ITR rotors with no prb and no clearence probs?
any yr NSX?

my head a splode....

yes. you can use the ITR caliper carriers too, I think you have to with the later NSX calipers.

Your pretty sure for someone that is incorrect. Yes the NSX caliper will bolt to the ITR knuckle and will work that way.................but its not correct. The rotor is not centered in the caliper. To properly install them on a ITR knuckle you will need a 2 mm thick washer between the caliper and the knuckle. This will ceter the caliper over the Legend rotor and help prevent uneven pad wear.

my prelude vtec rotors, originally 4x114.3, are 11.1". not sure what year prelude you're talking about, but i bought 95's from napa for 20 bucks each--lifetime warranty too.

 

After posting this I realized I was wrong..

Inserting foot into mouth now..

incorrect? ummm... okay. funny, been on my car for 2 years, prior to that on yasu's itr for 3 years. no uneven pad wear. stock itr carriers, stock size itr rotors

lol...

 

You are using stock ITR rotors (23mm thick?) vs my old set-up with Legend GS rotors (25mm thick?)

Ok so with ITR rotors it is a direct bolt on, With Legend GS rotors it requires a 2mm washer.

Mistrial

Thanks for everyones help. Dropspeed you are correct I have a DX so my stock rotor is 9.1" I forgot that the EX are 10.1" stock which mean their mounting tabs on the knckle will be slightly longer than the DX ones whicj will clear the 11.1" Prelude/NSX rotors.
To confirm I tried the NSX caliper on my friend's 99 EX and yup the tabs are slightly longer on the EX.
Here is a pic
