I was just wondering if the front rotors off of a 90-93 Integra would work on a CRX Si. . would i Have to change the calipers or would it just be a direct bolt on?

 

you will have to change the whole spindle
really easy, upper ball joint, lower ball joint, tie rod and brake line and
you are done, just need to bleed the brakes

 

Too bad the spindle is 1/2" taller and will mess with geometry. Keep DA with DA and EF on EF, two different chassis entirly.

 

which geometry is that?
other than getting the car realligned, there is no other problem
we in the autocross world all use integ brakes upgrade, same as the jdm sir civic and crx

That assumption is heavily incorrect, look at the two units side by side and even a two year old would notice differences right away.

 

Does anyone have picture of the 91 EX fronts vs the 2nd G integra? I have the EX ones, but I don't have an integra spindle to compare it to.

 

I have both the '89 DX Hatch and the '91 Integra front spindles at the house. Give me a day, and I'll get some pics of them side-by-side. Also, of the rear Trailing arms.

 

Here, I dug this out of my own personal archives since I got tired of writing it so often.

These parts bolt on (but only the knuckles/brakes). I have had experience with almost every possible combination on my daily driver hatch, and my conclusion after measuring a number of different parts and installing them, you can only use the knuckle/hub assembly from the appropriate models to retain the proper suspension geometry. That's not to say that other combonations won't work, just not properly. And even with a camber kit installed, you are only compensating for poor geometry somewhere if you are using the DA parts.
As for the rears, on honda's, it is usually best to retain your factory trailing arm and just add the brake to the stock arms. Here again many combo's will work, just nothing properly. DA's arms will give you more positive off set in the rear, and the lower control arms will give you negative camber.
Many people have opinions, because as I stated, many combo's will "work". Just do the math and measure some parts and the picture will instantly become clear that only certain parts will retain factory geometry. </TD></TR></TABLE>

 

Why not just get 4door ex front spindles? Best factory honda brakes for ef and they have correct camber also.
