Yeah you can upgrade to mk2, calipers etc, think im possibly sticking some toldeo brakes on mine if it all works out that way anyway - like Jay said, the mk1 section does hold more in depth threads...
also afaik, changing your drums to discs doesn't have that much of an effect on the breaking, more of a looks upgrade
also upgrade your servo and breaking also depends on what discs/pads you buy
