Larger disk, even better.
Changing from the original Spit brakes to the GT6 MK III brakes and dual
Tilton MC's in my Spit made a world of difference.

Beware the geometry when you do this. If you don't set it up right,
loose one MC (or the pushrod to one MC) you loose all breaking as the
pedal goes to the floor and the balance bar just pivots. Been there, got
the scuff on top of my helmet from subsequent rollover.
