improving a losi 8 1.0

[dodgydiy]

i have a losi 8 1.0, dont do that many meetings with it and cannot justify the cost of buying a newer car, it is standard apart from hinge pin braces and collars on centre shafts. I really just want to improve the handling a little, have messed about a bit with setup but havent got it right for me yet. does anyone have any reccomendations on things they have changed or modified to improve the car, or would you just get a 2.0 chassis and centre shaft for it...
