Difference between M and other brakes

[gooten1]

What's the diff between the brakes on the M and the ti? Also, did the club sport have bigger brakes?

M rotors are larger, my guess the master cylinder and pads are larger too.
Also the steering knuckle is different.
No, the ClubSport did not have bigger brakes. Every model used the same brake setup until 4/98 when they went to vented rotors.
