I know this topic has been beat to death but I have some quick questions if someone can help, I am doing the ITR 5 lug convo on my 99 GSR, and I am looking into the NSX caliper upgrade.

I AM using 15 inch stock ITR wheels, so I have two questions.

I know I need to buy the NSX caliper and bracket, but can I use the stock ITR rotor I have? Or should I upgrade to a NSX or Legend rotor?

Do I have to use the pre 96 NSX calipers to fit in a 15 inch wheel? I heard that the 96+ does not fit in anything smaller than a 16 inch wheel.

Thanks guys!

 

Also any info on the rears? Can I put NSX rear calipers on stock ITR rear rotors? and will the bracket fit?

 

yes, you can use the 15" oem ITR wheels (on your 5-lug conversion) with stock ITR front rotor with NSX calipers if you use the ITR's 23T bracket.

you must use the bracket associated with the rotor.

the 23T is meant for a rotor which is 23mm thick (oem ITR, prelude VTEC).

the number on the bracket (ie., 23T, 25T or 28T) determines the size of the rotor it will accept in millimeters.

the issue is the clearance of the hanger and offset of the rotor.


1. ITR 23mm rotor, use the 23T bracket
2. NSX 28mm rotor, use the 28T bracket

NA1 (91-96 NSX) & NA2 (+97 NSX) front calipers both accept the same brake pads (same size as ITR)

NA1 & NA2 NSX front calipers have:
1. different size pistons sizes
2. different brackets (NA1 vs NA2)
3. brackets interchangeable

15" oem wheels = NA1 or NA2 calipers + 23T brackets + 11" 23mm rotors (oem ITR)

1.) If you continue to use the stock ITR rotor, you want to use the stock ITR bracket.

2.) All NSX calipers have the same overall dimensions. Only the piston size changed between the 96 - 97 model year. The brackets also changed, but that doesn't effect you since you're using ITR rotors. For example, I'm using 97-05 NSX calipers with the smaller 11.1" diameter, 25mm width rotors from a '97 Acura 3.0CL.

 

ive had nsx calipers on a 4lug with some SI


u just need the rear brackit off the itr's

 

THANK YOUUUUU! I have never had a question answered to well! thanks dude!

 

Theres no way I can do it myself? Cause that's kinda pricey not including calipers.

 

that's nice, BUT why clutter this thread?

let's stay on topic here:

the OP needs info on
1. rotor set-up for NA1/NA2 front calipers on his 5X114.3 knuckle/hub on oem ITR 15" wheels
2. rear NSX calipers on 5X114.3 ITR rear trailing arm

what? yo stop posting mis-information smh

negative...the NSX rear calipers (stamped 14CLP15V) will NOT bolt-on to the rear ITR caliper brackets

 

de nada

agreed; it gets really expensive really quick.

when you tally up all the costs of obtaining:

the NSX rear caliper & pads
fastbrakes kit, adapter bracket & 11" rear rotors
$320 (plus s&h)

the NSX rear calipers will not bolt-on without a custom adapter bracket & 11" NSX rear rotor


NSX rear calipers on ITR 5-lug
https://honda-tech.com/forums/acura-integra-type-r-8/rear-brake-upgrade-my-type-r-2836406/

imo, the NSX front calipers/11" rotor/23T bracket + stock ITR rear calipers/10.2" rotor
(5X114.3 trailing arm) are more than adequate and functional

there's not a whole lot of info or feedback out there for the 11" NSX rear caliper swap.

the NSX 11" rear set-up is really meant to balance out any front bias from 11.8" front rotors & larger BBKs.

keep in mind, the all four NSX calipers set-up all around on an NSX was designed for a mid-engine RWD;

while a NSX front & back on our front mount engine FWD integra/civic, might create some rear bias

(although it has never stopped me or anyone else from trying)

 

Will the fastbrakes set up fit the rear with my 15 inch wheels?

 

How hard is it to to custom make the bracket? If I was to do so should I use a ITR rear bracket or a NSX rear bracket?

 

i dont have any specs on hand, not 100% sure of the rear 11" NSX calipers' offset (with the adapter bracket) in relation to the oem ITR wheels. if it is an issue once it's installed; most likely, this can be easily remedied with spacers

 

Fastbrakes.com is the only company who makes the adapter kits.

besides fastbrakes, BrakeExpert (who is no longer on this forum) fabs up custom adapter brackets, for NSX rear calipers

 

you must use the rear NSX carrier/bracket for the rear NSX calipers

look at the pic below...the ITR rear bracket physically wont fit on the NSX rear caliper

again, the NSX rear caliper is NOT a bolt-on, it requires a custom bracket.

Ok I think i got everything I need, thanks again, would you say this is worth it vs a real big brake it or a stock ITR setup? I'm doing it more for looks than anything not gonna track the car, but I'm trying to see if the cost will make sense. I can't find a rear big brake kit for 5 lug anyway.

 

depends on your goals, your car's purpose (& how much money you're willing to part with...lol)

here are the facts:

1. 94-01 integra (regardless if LS, RS GS, GSR) in 4X100 comes equipped with 10.3" front brakes & 9.4" rear disc brakes

2. the ITR 5-lug (in 5X114.3) comes from the factory with 11" front brakes & 10.2" rear brakes. the ITR's front & rear caliper pistons are larger than the integra caliper pistons

3. aftermarket set-ups
a. such as wilwood, spoon, stoptech, mugen, brembo
b. adapter brackets (ie., aem, fastbrakes.com, etc) to keep stock calipers on custom rotors, etc

keep in mind, upgrading calipers will increase your rotor size plus add weight

increasing unsprung weight raises the load placed on controlling the motion of the wheels and tires during acceleration

 

the brakes from the ITR can be modified & duplicated for 4X100 for much less than the cost of a 5-lug

 

form over function

if you're not tracking the car, dont bother; you wont see their full benefit unless you're on a track.

it seems like a lot of money for some bling, the only difference you will feel is better modulation which is pedal feel.

unless you track your car often you wouldnt notice

for the purposes of daily driving:

the brakes on your 99 integra GSR's brake system are more than adequate

your 99 integra GSR brakes would benefit from a quick inspection & fresh parts.

you might want to consider:
good set of pads,
new blank rotors,
some grease,
fresh brake fluid & tires.

Thanks dude ur answers are really well written! Right now on the GS-R I have brembo rotors from and back drilled with hawk pads and its amazing stopping power! I love it, like I said the only upgrade reason is 5 lug for looks and wheels and NSX for purely looks. I know its all the wrong reason to do it but I just want something nice, in case in a couple of years I want to track the car.
