you should be able to upgrade it if you want but if its a running cart it may be worth trying to sell it......might bring enough to buy something newer and already upgraded .....you know the cult following they have should make it worth something to someone but if not you should have no trouble upgrading the electronics.......as for brakes they sell a front disc brake kit but you,ll have to find out if it will work on it.......i don,t see why it wouldn,t......................
