Here is a little picture...still need to take care of a few things...

'90-91 EX knuckles
'92-96 Prelude 11.1" rotors, redrilled to 4X100
Type-R calipers

Some grinding necessary....need to take pictures of the grinding, next time I'll have pics of it installed.

What else gets installed...
1" MC
Integra booster
new prop valve

 

does the prop valve control the pressure of the brake pistons left and right? by chance? or should I look elsewhere for uneven braking pressure, sorry 2 threadjack

 

That's awesome!

I'll be there soon, but probably with NSX or Legend calipers.

Did you do the 4x100 redrill, or have a shop do it?

good stuff austin

 

Austin always has the coolest stuff.

 

Very cool, stopping power yo!

Prop valve controls front and rear bias, iirc.

if you have uneven left/right brake bias, then you might want to check the lines and calipers.

hth

k, i thought that's what the prop valve controlled, lines are new, one caliper is newer than the other, i guess the drivers side is ragged out now, might just replace both at the same time

 

.....do the siR knuckles or 91 ex knuckles have mounting points for abs sensors?

 

I rock the exact same setup on my street kaa

And don't your rotors warp every other week?

 

what year integra powerbooster is used? 90-93?

I had mine done at a machine shop. Removal is .115 to .118 inch (apx. 3mm).

dam those are some huge brake rotors lol..

do you really need a 3000lb cars stopping power..??

 

Here you go buddy, been there done that.
I did mine with no grinding necesary when I did the type-r calipers, w/prelude Rotors, and Kosei K-1's

crx bart. on your write up it says that u cant use the civic ex mc 15/16 cuz they have diff bult pattern. im using the 15/16 off the 91 civic ex. i did the same swap but stayed with the 10.3 setup. im running the 91 si rex prop valve also.

Have you tried fitting the ITR calipers under factory 15" wheels without milling the caliper bracket (I'm talking about where it <u>attaches to the knuckle</u>, as per the picture I posted above)? Did you run into any clearance issues with the inside of the wheel, or uneven pad wear?

I'm asking this because the clearance with that setup & the factory wheels is very tight. I have had the 15" Si wheels, and two different sytles of 15" integra wheels mounted with that setup.
I also went through 2 sets of pads & rotors. Pad wear was normal - in fact, I still have my old pads.

I now run the 94+ rotors/calipers on EX knuckles (which I would agree there is no machining necessary on those, including of course the EX brake setup).

You know what you are right, I almost forgot about it. I did grind the caliper mounting plate. Where the mounting threads are, it edges out about 1/4" I grinded that flat, then it fit right up. I just used a bench grinder, and a belt sander to grind it smooth.

 

wilwood 4 piston calipers for me

 

Does a brake upgrade of this kind only work with EX knucles? What can a guy do with the si/dx knuckles? (I have a swapped HF)

fastbrakes, other than that upgrade to ex knuckles.

Aren't NSX calipers like 7lbs each??? from what i heard?? thats goign tob e some heavy brakes

 

I'd swap to the NSX calipers and lude rotors if they were cheap enough ( which is kinda impossible ).

On the other hand...

I saw on "sports car revolution" that they lost something like 10whp by upgrading the brakes on there mugun project acrua RSX-S, and that's not counting the weight of the caiplers, that's just power lose from increased rotor size.

But you gotta stop before you can go...

I choose a cheaper, more "in the middle" route. 10.2 inch DA brakes all the way around ( 9.5'' in the back ) with steel braided lines. Still waiting on the MC/brake booster to come in the mail, which is also off a DA.

The legend calipers are deffinately going to look huge from what I've seen pics of, but your still only going to be able to stop as fast as your tired let you, so I hope you have some toyo prox RA-1s...

If I could do it again, I would probally just do 10.2" EX brakes on my REX. As it stands now, w/ the lude, accord wagon, civic ex hybrid, I can only fit 15" wheels, which kinda blows. I'm sure cutting down that mass on the outer diameter would help also, but nothing beats jambing those bitches on at like 85 with no brake fade, and breaking your occupant's collar bone. I love doing that test on people.

</TD></TR></TABLE>So what did you do Austin? Pull your old ITR brakes off and mod them for the rex? So what is your R stopping on now? BTW I found some OLD pics of your first R at Sac raceway. I still love the shots of those Mugen's....
