Hi all,
Hope someone can help me with this. I read something interesting the other day on the net that eg and ek civics were produced with two different size discs. 90-03 civics were said to have either a 240mm disc or a 262mm disc (years 94-03). I have two questions: why would Honda vary the disc size on different models? and what size discs would a facelifted ek1 hatch have?
Would an extra 22mm make that much of a difference in stopping power?
Does anyone have any answers to this?
disc size increased to accommodate a larger caliper... so once again disc has nothing to do with the extra stopping power... more about caliper piston being larger and hence more bite.
To the best of my knowledge EK1 had 10.3 inch rotor... ie 262mm.
type one - always full of useful knowledge :D. Thanks :thumbsup:.
Can anyone else confirm this?Quote:

yes ek1's have a 262mm front rotors
Thanks for the confirmation :thumbsup:.Quote:

Anyway, the initial limiting factor for braking force in any properly functioning car will be the tyre's grip on the road. The next concern becomes the brakes ability to absorb and dissipate the heat generated, the former is largely a function of the discs mass, the latter depends on the design, airflow, relative temperatures etc. But the simple answer is the bigger brakes will have greater braking capacity.Quote:

Hot Gem,
Top of this class! Of coarse a larger rotor will increase braking power, and all the other factors he lists.
