I have a '90 CRX Si, currently with Integra front spindles, rotors and calipers. I plan on doing the Accord Big Brake upgrade with the wagon 17c115vn calipers and 23T brackets. My question is what car runs the largest diameter 4x100 rotors?

same ol Steve

VW Corrado 4 cylinder(G60) cars use 4x100 11'' rotors that bolt on thats what Fastbrakes uses

kess

I need 11" rotors so this will work.

CRX Toad

With that setup you have to use the 11.1" rotors. Nothing bigger will fit. Also I use the Legend or Prelude rotor and redrill it 4x100 I have yet to see the Corrado rotor work properly without the Fastbrakes kit.

kess

So you take the rotors to a machine shop to have them drilled to 4x100? Because I cant be that precise with just my drill press.

Will Brembo or someone else sell me blanks, so I can get them drilled properly?

kess

So where can you go to get 'blank' rotors?

And what year Legand rotors work on this swap?

88Hatchy

these are on my buddies CRX. I forge the P/N and exact size.

kess

Hatchy PLEASE get me the specs on this system? I have concidered NSX calipers for some time now. I have contacted several companies and no one yet has any source for blank rotors.

PM iskate2, it's his car. He should be able to get the info.

Talk to Brian.

Thanks Targa - great link. Just wish I could pick apart Fastbrakes systems so I could put it together myself. Seems like Im always tweaking something...

Hatchy, thanks for the link to iskate2. I have PM'd him but I also emailed you asking about the system. Oops!

Anyone know the setup to put NSX brakes on a CRX? That would be my ULTIMATE setup for track days! Also thinking about '90 'Teg rear suspension with cyro-treated rotors and Hawk HPS+ pads. So... any thoughts about rears? I also have a '88 CRX SI and am thinking of installing my (old) '90 CRX Si rears on that car. Yea, I like donking around on them...

Targa250R

What's wrong with the 10.3" rotors and 17CL14VN calipers you already have? They're fine for most tracks on a 2200lb car with 160-170whp. How much power could you possibly be making with a supercharged D16?

I was just about to ask a similar question.....and a few others. I was just performing a rear disc conversion on a 91 CRX (97 GSR rear discs) and was considering something larger than the GSR front discs. I know the Civic/CRX discs are 9.44" (240mm) and GSR discs are 10.3" (262mm), what sizes do the Legend or Prelude run? I am machining brackets for Wilwood calipers, not limited to rotor size other than using 15" 2000 Si wheels.

Not trying to steal your thread kess, I am on a similar quest

No problem Kirk. Any bit of info is helpfull, and I didnt know that you could put GSR rears on a CRX.

Targa, the reason I am so obsessed with big brakes is the fade issue. The straights at Road America are the longest in North America, and brake fade is a serious issue. My current Integra system is fine for normal street use. BTW Im dynoed at 155 WHP, so you were right on.

Anyone know a source for NSX calipers? I have been e-searching and have not come up with anything viable - yet.

Targa250R

What sort of fade problems have you been having at the track, and what pads and fluid are you using?

It's not the long straights that get you - those offer cool down time. It's the tight turns immediately following long straights, and Road America has a lot of those. If it had more sweeping turns, it'd be a bit more forgiving.

neofreak

like everyone else has said. contact www.fastbrakes.com, take a look at the website. i just ordered my brakes from him

KRock459

I got the full GSR conversion (control arms, spinles, calipers, cables, ect) for the rear, I should have been more specific. I know the GSR rotors fit any 4x100 hub/spindle, but the brake caliper allignment is the concern. I plan on machining front caliper mounts, so I can do any rotor that will fit the hub and work inside the 15" wheels. That may be something to consider for your application as well, if the NXS calipers prove hard to find and are too much $$.

Kirk R

kess

Yea Kirk, I heard that you have to grind the calipers so they will fit. Thanks for the tip on the GSR setup. Anyone have a rear GSR suspension for sale? I would put it in my '90 Si and put the OEM '90 one in my '88 Si (Drum brakes). My bearings are going in it so now would be the time to upgrade to rear discs.

Targa, yea, I know the straights cool the brakes but the turns are brutal at R.A. - specially #5, coming off the back straight. My current setup is Integra front suspension with K&N 2" drop springs, Brembo slotted rotors, and tokyko Blue struts (Koni Yellow adjustables sitting in the garage) and strut tower brace. Hawk HP pads, Goodridge SS brake lines and Wilwood 600 degree brake fluid. Rears H&R 2" drop springs, Tokyko Blue struts, and strut tower brace. I have new cyrogenically treated rotors, Hawk HPS pads, and an Integra rearsway bar in the garage. Also running an Integra MC with stock proportioning valve. So its all I need for the street but you always gotta look out there to take it to the next level for track days. NO WAY would this be SCCA legal for most classes!

So... anyone have a '90 - '93 Integra rear disc setup, or a GSR? Or what have you??

Targa250R

There is no difference between "GSR" brakes and RS/LS/SE/GS Integra brake components. They all use the same calipers, pads, and rotors. The only Integra with different brakes is the ITR.

'92-95 Civics with ABS and '92-95/'99-00 Civic Si have those same rear disc brakes, as do the del Sol Si and del Sol VTEC.

And FWIW, the '90-91 CRX Si rear brakes are the same as the Integra rear brakes. The '90-93 Nissin 7CLP13S rear caliper body is just slightly different than the '94+ 7CLP13S-R3 body, but functionally the same.

The only thing you have to watch out for is trailing arm bushing size in the '90-93 Integra trailing arms - it's a different size than all of the other trailing arm bushings, so you'll need that specific one if you're replacing the bushing when swapping trailing arms.

Why don't you just get some actual track pads and swap them out at the track, instead of buying all of this extra brake hardware?

thedudefromjerz

I actually bought the wrong trailing arm bushing for my trailing arms. Does the 90 - 93 integras have the smaller or larger bushing in the trailing arm?

LightWeightChamp

I just got my rotors and calipers back from the machine shop today. I used prelude rotors and had them redrilled . Just need to get and integra booster and ill be done with the setup

same ol Steve

The 90-93 Integra uses the larger bushing and also widens the rear track about .25''+/- on each side on a Civic or CRX.
I put the DA arms on my mildly lowered,H&R sport springs & Koni yellows, 91 hatch and changed NOTHING else with my 15x7 40 offset wheels did not rub before I did the swap but after it does. Not a major rub but if there is an extra person or at some speed bumps it will barely scrape more of an annoyance but it still bugs me.
Remember to clock the new bushings on a lowered car so they are not preloaded at normal rest it will make them last a lot longer.

kess

Steve, thats almost exactly the setup I have on my '88 CRX. Thanks! Please describe 'clock the bushings', as I am considering replacing the bushings before installing the DA disc setup in the rear of my car.

durfeec

i believe he mean instead of lining the bushings up level to turn them a lil bit so they sit levell again when the car is lowered.

kess

OK

Please let me be the dumbest thing here. Is there something on a bushing that allows me to 'align' it? And if so where do I rotate it so it will be correct once the car has all its suspension parts in place and sitting on the ground unassisted?
