I'm planning to do the ITR sized front break rotor upgrade on my '92 Civic CX as in the hybridhonda-perf.org.

I've also read the article on this forum.

In the hybrid article, it makes it sound like if I get the Prelude VTEC rotor, it would be a bolt-on, as long as I get the Integra knuckles.

On the other hand, honda-tech.com thread makes it sound like I need to get the rotors redrilled to 4X100 pattern.

Which one is right? What's the bolt pattern on the Prelude VTEC rotors?

 

u have to drill the prelude rotors to the 4 by 100 bolt pattern. the prelude bolt pattern is 4 by 113mm.

 

 

thanks guys!

I've contacted fastbreak.com about the redrilled prelude rotors.
