If you want better brakes after you've done the reaction bars and braided lines (which I agree are must-do items) then you might want to consider fitting 4-pot calipers rather than a servo.

Both have the advantage of increasing the braking effort distribution to favour the front wheels, the stock setup makes it too easy to lock the rears, but the 4-pot caliper option has 3 advantages over the servo route:

1. You lose a bit of weight, the alloy 4-pot calipers are lighter than the iron 2-pots
2. The 4-pots give a better braking feel
3. It's a simpler job, no need to plumb in a servo unit
