Everything you need is detailed here:
First thing you need to do junk the stock springs, get soft springs for the rear and hard springs for the front. I would start with 30W oil in the rear shocks and 60W oil in the front for a loose pack track or 35W rear and 45W front for a high traction track.
Don't even consider sway bars, maybe for the front only if your rear end keeps breaking loose.
Diff oil all depends on track conditions too.
The biggest killer for you is no droop screws, you're gonna need to put fuel tubing inside the shocks on the rod between the e-clip and the inner piston to control your droop setting, very painful and tedious for tuning, but that's Traxxas for you
