This is the biggest headache I've ever felt with, so I decided I needed to upgrade me front brakes on my 92 Eg hatch (b20vtec on 6psi) and I bought the wilwood 4 piston brake kit, when I first installed it I did exaclty as the instructions said, also I should say that I am a mechanic so I know what I'm doing. When I first installed them with the rotors torqued down with lug nuts I could not move it at all because of how much they rubbed the pads. (Because the rotor isn't aligned with the caliper) so I called wilwood and they were no help except they told me to get a shim kit, which I did 3 different size shim kits. And still I can't get the caliper to sit right in relation to the rotor!! This is really frustrating I can still drive it but there is a gap on the pad and it doesnt fully contact the rotor.
Yes I milled the rotors trying to get more clearance
What wilwood kit did you purchase and what size brakes were originally on that car? The 9.5" or 10.2"? It immediately looks to me like you have the wrong kit for your knuckle.

Well the kit I bought was for the 262mm rotors and that's what was on my car, and they are abs knuckles, and I thought the same thing and bought a pair of integra knuckles and they looked exactly the same with the same numbers on it....

Could the knuckles be different from integra and still have the exact same numbers and look the same? I just put extended studs and a new bearing in these knuckles so i didn't want to swap them but I'll prob end up trying...
I find it odd that Wilwood just told you to shim it. That's a fair bit offset, something isn't right.
yeah I'm ganna grab a knuckle off a integra at the junkyard and try it, but it's stupid because the ones on my car look exactly like integra knuckles,
They have the same numbers on them as the integra ones aswell as a spot for the abs sensor
1. You have a 1992 Civic Si, which came stock with 240 mm rotors.
2. You bought Wilwood DPHA calipers, which are made for 262 mm rotors and corresponding knuckles.
3. You installed 92-95 Civic ABS knuckles, which are made for 262 mm brakes.
4. The rotor is not centered on the caliper.
I'd suggest you check if you really have the right knuckles, calipers and rotor offset.

First of all, I think you have the right knuckles. The 240 mm knuckles have a different bolt patterns exactly to prevent the wrong calipers from being installed.
Unless there is some type of 262 mm knuckle I don't know about, you should be good there.
Therefore I can only see 2 options:
1. Wilwood did a shockingly bad job designing the calipers, or sent you the wrong parts.
2. Your rotors have the wrong offset or there is a spacer between the rotor and the hub.
To test the second hypothesis you can measure your rotors and compare with this reference drawing:
well I bought the car with these knuckles already on it, but it had 262mm rotors, but yeah I'm just like wtf at this point wilwood says nobody has ever had problems with there kit so I'm going to try a new kit maybe.

and also one side the caliper says wilwood facing up and one says wilwood facing down, shouldn't the letters match per side? But that still doesn't make sense why they both dont fit very well. Wilwood told me that I need to shim because not all knuckles are the same when they are made, because they are mass produced

Michael, I can verify for you by looking at it that those are the Integra knuckles, similar to the Civic EX. a 93 Si should have STOCK come with the smaller knuckles (using the stock 9.5" rotor). The EX/Integra knuckle used a stock 10.3" rotor, and the mounting tabs for the caliper are about 2/5 of an inch farther out.
If you want to upgrade those to run a radial mount caliper LMK. I just completed my FNSL6R setup for half the price of FastBrakes, and I can use the AP Racing caliper setup for $500 less than ASR.
looking at the pics several times over it looks like the rotors are not seating all the way on the hubs, and by about the same amount as the shim thickness you added.
They aren't seating right cause the pads are hanging off the outside of the damn rotor, so they are tapering (twisting cause theyre not contacting dead flat as they should.)
That caliper/rotor combination does not work with that knuckle. Gotta change something.
