The purpose of this is to show that DA knuckles can be used as opposed to EX knuckles with out any major alignment or suspension issues when doing the 11” brake swap.

It’s important to note that after the initial readings were taken, but before the final alignment was done a upper control arm bolt came loose and therefore the true before and after readings are not known, but since this car is not equipped with adjustable pivots, the change is minor.

The difference between the DA knuckle were noted to be the same as what most people found, about .25-.30 taller, however the steering arm is quite shorter. This should provide a quicker ratio and more effort required to steer the car

The car has not been corner weighted, during this test the ride height was not changed via the coilovers, nor was it checked. With this being said, spending some time to corner weight and level out the car could end up with even better results


The parts I used are as follows;
DA Integra knuckles (Thanks Toad)
DA Integra 290V Booster and M/C
93 Legend Calipers (Brackets milled by DrDisco69)
93 Legend Rotors redrilled to CRX bolt pattern.

Of course this requires 15” wheels

The beginning alignment specs with Si knuckles were

....................LF............RF
Camber____-3.8______-2.3
Caster______3.3______2.9
Toe_______ -0.27_____0.72

After the swap and some tape measure toe adjustments to get back to the alignment shop. Note the steering wheel has been off of center until the final settings were made.

.....................LF........... RF
Camber_____-2.9_____-3.6
Caster_______3.0______2.6
Toe_________-1.11____0.23

These are the final settings that we were able to achieve using the factory adjustments.

....................LF............RF
Camber_____-2.9_____-3.6
Caster______3.0______2.6
Toe_______-0.12_____-0.11

Upon first sight it looks as though the knuckles make the camber all out of whack.
Keep in mind this car had a loose driver side upper control arm as mentioned above between the time the initial specs were taken and the after specs were taken.

If there was a trend of the tall knuckle really throwing off camber curves and such we would see the same trend on both sides of the car. If you notice the values flip flopped from side to side. I suspect that this is due to machining differences between the two knuckles.

This has been a little project that Trakhor, DrDisco69 and myself have been trying to weed out some mis-information that is out there on the interweb. This setup is currently running on Trakhor's Si.

This makes me happy. I was a little worried about my DA knuckes and camber.

One thing to note here the steering is a little harder to turn when sitting still. This is from the shorter arms on the knuckles. Other than that, the driving feel is the same as stock.

Great news!
There really was a lot of misconceptions out there about those hubs/knuckles. Its about time someone took the time to actually measure them out. So glad I can keep my da knuckles
Anyone know of a good method of pressing hubs in and out at home?

If you don't have a press, good luck. chances are something else will get destroyed in the process. I don't know how it is in your region, but you can typically get that done at a machine shop or a really good parts store for cheap....if you know the guy well he might do it for a 6 pack of his favorite brew.

Would this explain why after i did the Si to DA swap, my wheels were pigeon toed? Meaning pointed out.

We had to spend some time adjusting the endlinks enough just to drive it. A professional alignment is in the works, of course.

Bingo, my initial alignment specs were after turning the tierods out 3 turns

Hold up....so what you guys are saying is that the DA knuckles could be used just as good as the EX knuckles?! How would it affect autox or any other driving that relies on turning the wheel? I'm wondering because I really want to autox my hatch and I've been searching high and low for EX knuckles because of hearing that the DA knuckles would be bad for my alignment which would lead to premature tire wear right? But I guess the DAs aren't so bad? Sorry for the rambling people lol.

I did the same thing a few years ago with before & after alignment sheets with DA knuckles and found similar results. However if you use DA rear trailing arms when doing your rear disc brake conversion it will push the wheel .25-.5 inches outward

I have DA knuckles on my CRX, and the car handles great. I also have Progress coilovers, Skunk2 adjustable UCAs and Innovative's Pro traction bar.

My latest alignment specs are:

Camber: -2.6 -2.6
Caster: 6.0 6.0
Toe: -0.17 -0.17

So, it is possible to achieve a proper alignment after the swap.
