im pretty sure the center bore of the corrado rotor is 65.1mm and the hub center of a 93 civic si is 64.1mm. please correct me if i'm wrong.

so where can i get 65.1mm - 64.1mm hub centric rings? i looked around online and it seems to be an odd size

 

I might be wrong but isn't the "hat" of the 11'' Corrado rotor a different size?

I think it will fit some honda hubs but not others. I think its safer to re-drill Prelude VTEC rotors.

 

im using the 11 in corrado rotor with s2000 calipers/ milled brackets/pads. the caliper brackets were milled 2mm on the mounting surface to account for the different hat size

i mocked it all up on the car and it lines up perfect and clears my wheels but the rotor is slightly off center so i wanna get hub centric rings to fix it before final assembly.

 

Good luck. But why are you using 11 rotors with the S2000 calipers and brackets when you should be using the RSX TypeS 11.8" rotor?

When using RSX TypeS / S2000 calipers, they use 11.8" rotors stock. RSX TypeS rotors are hub centric and need to be redrilled. I've been using RSX TypeS rotors and calipers on my Integra for the passed 3 years with zero issues.

 

The 92 si knuckles are the same as the lx knuckles, so the tabs for the caliper are closer to the center. S2k calipers would not clear the type s rotors. The 11 in rotor is a perfect fit since its already 4 lug, it just needs to be centered

 

gotchya.

 

I have the same setup but with the rings too. I tried RSX-S rotors, s2K calipers with 99si spindles and the brake a little far from the center. Maybe 20% of the pad is not in contact of the rotor. SG60 is the better setup esp if you have Hawk HP+.

 

i ended up buying rings that were a little too big and having a machine shop turn them down to the right size. u just got them back this week actually, ill be hopfully doing the sg60 setup this weekend

 

ok so i finally got a chance to put this together and on the car. i had a local machinist make the rings to center the rotors. one shop wanted $150 each to make them, the one i went to didnt even charge me. i assume the first one just didnt want to do the job

anyway, i it all bolted up great. i had to grind a little more off the caliper bracket on the one to clear the tophat. but otherwise it went very smooth.

before (no the studs are not broken, i was just halfway through taking the wheel off):

and a shot of the car to compare front to rear:



looks like next week ill do my ep3 rear breaks and 1in master cylinder

 

very nice!i did mine too but my disc seems to be larger than 11 inches because the outside is not in contact with the pad and it rubbed a little bit off the inside of the caliper and bracket.
aslo s2000/rsx-s pad is smaller than my dx one!

 

The magic numbers for the DX to s2000/g60 conversion are 65.1od and 56.1id
