HD Drive gear is a must!
I personally think that the rear tie rod eliminator is great! Not an immidiate mod. But you will realise how annoying the rear tie rods are if you jump often!
sway bars really help the savage as it likes to topple over.
Sway bars combined with the shock mod really transform the handling.

If your not gettinig an RSC then you should do the hub mod to increase steering.

Also its vital to change the servo saver for the HD one as the stock one is rubbish.
When you servo blows, then get a stronger one.

Then just upgrade parts as they break.

You may want to get some shock oil and diff oils
