Alright I have the following ready to be installed

ITR calipers w/brackets
ITR rotors redrilled to 4x100 (Dont have these yet but I am picking them up soon)0
DA Integra Knuckles
Carbotech Panther Plus
ITR 1" MC

My question is this: Can I use the Si booster, or do I have to upgrade to an ITR booster?

I am really excited about putting these on. All I need now are some rear disc brakes.

 

With the ITR calipers you need to have the bracket milled 2.5mm-3mm in order for it to work properly. You can put washers behind the rotor but this is NOT the best course of action! So please get the bracket properly done.

The ITR MC will not bolt up to your Si booster. You will need to use the ITR booster. You can however use the booster and mc from your Si until you get your other booster and MC. Make sure you use a ITR booster. You cannot mix and match ABS boosters and MC's with non abs stuff. And yes you can use ABS booster and MC on your CRX.


Also I had to drop 3 of the 4 motor mounts to get my booster and MC in my car so just be prepared to do this if you have too.

Also here is the basic break down of boosters there is a tag on the top that lists this info
205 V (vaccum) 88+ civic base model
231 V EG Si
260 Integra GS,LS, some GSR
290 Integra ABS

I have th 260 on my car with the same setup you are doing and I feel that a 290 maybe too much for a daily driver. I move the pedal about this much | | and I am into the brakes.

 

Thanks for the info.
