someone is selling ek civic front knuckles and hubs in the classifieds. i was wondering if this will bolt up to the front end of my 91 crx. i am sick of the horrible hf brakes and i want a descent upgrade. please help me figure out if these knuckles will fit. also if the do fit whould i just use si crx axles or would i have to use a civic ek axle? thanks for the help in advance!

Yup, They fit. You can use an Si axle. Aren't the HF axles smaller? but a Si, Dx, Ex axle should be all the same. This will give you a 10.3" brake disc. You'll need the calipers too.

I'm doing it right now on my summer car. You should also get a larger master cylinder. I have one from a 89 prelude. it has a 1/8" bigger bore. does not sound like much but a HUGE difference. Pedal slop is near gone and have next to no travel to full pedal pressure. A lot like the Brembo Gran Turismo Kit. I have felt them on a S2k and pedal feel was similar(not saying the same because you can't compare $250 junkyard big brake set up to 1200 set up)
Oh ya, I'm not sure if your gonna want a different proportioning valve. I know you do with going to rear disc. I believe it should be the same valve between all civics. I'm pretty sure Honda only made 2, one for rear disc setup and one for rear drums.

thanks. yes the hf axle shaft that goes through the hub is much smaller than the si shaft.

i may finally have decent brakes!

i dont think the axles from the Ef will sit right in the Eg knuckles..i read somewhere that its a tad bit different. just by a hair. maybe get the lower control arms from the EG. I think it had something to do with the distance from the Knuckle and the chassis of the car. Look into it. do a search on Here..

then could i just use and eg axle to make up the diffrence?

Not EG they are EK knuckle. EG are different. but EK. I should have read closer I though you had Ex knuckles. Like the 1.6l MPFI 4dr. The had bigger brakes and knuckle like an integra. All other honda civic 88-95 had 9.5" from rotors, expept for the b16 Del Sol I think

oh durrr...its said EK knuckles..no i dont think those will work...those are way different.

The Front suspension geometery of a EG an EK are different than a CRX. Just hit the junkyards there are lots of 88-91 DX/SI knuckles around, and if you get lucky you can score some 90-91 EX knuckles.
