does anybody know what size the front brake caliper piston is? i've searched but can't find any info

 

just wondering what you need it for?

 

well i just got some nsx calipers and right now i'm trying to calculate and compare some numbers.

 

well if you just look at the prelude faq's. you will see a guide to brake swaps.

the only benefits of nsx calipers

1. a little less weight
2. dual piston (doesn't mean it has more braking force)
3. and i guess the blingy part of it.

if you already have vtec calipers. i doubt you will feel the difference (unless the brake flush helps)

 

The OD is 2.25inches
