Shocks of some discription yes.. I use
Traxxas Big Bores atm. I've had to do some mods with the shocks, but they are nice. Later this year I might try the
TC Big Bores.
Also
Front hubs and
Rear Hubs I think are a must.
I'd also get some proper Turnbuckles.
And apart from a new bodyshell that's all I can think of as things I'd do...
