Ok i know this topic has been gone over many times...
i know itr calipers and prelude redrilled rotors to 4x100 works on the tegs,
but my question is why not use just the ITR rotors to and redrill them to 4x100?

thanks

4th gen Preludes have 4x114.3 bolt pattern. It's not too hard to drill 4 more holes in a 100mm circle, with each hole in between the holes already there.

ITR rotors have 5x114.3 bolt pattern. It's more difficult to add 4 holes in a 100mm circle and not have those holes interfere with the 5 holes already there. If nothing else, the strength of the rotor hat could be reduced.

 

I see now... but there is nothing wrong with using the itr rotors... they fit as long as they redrilled. it has nothing to do with the hub fitting or anything eles. using prelude rotors are just easier. right?

well like he just stated.. the itr rotors already have 5 stud holes. it would be easier to drill holes in a rotor that only had 4 holes to begin with.

This is easy, ITR rotors have a 70mm center bore and your hub is 64mm. The 92-96 Prelude VTEC rotors have the correct 64mm center bore to remain hub-centric. Also, you cannot redrill a 5x114.3mm pattern to a 4x100mm pattern without overlapping holes. You can redrill a 4x114.3mm pattern to a 4x100mm pattern without overlap.
