Just bought a SCX 10 Used

[621clay]

Few questions:

What battery should i use that will fit the Oem chassis for a Hobbywing 35amp 1200 kv brushless set up. 2s or 3s what what mah rating?

Also, what shocks are the best on the market?

And the best wheels? should i just stick tire weights on the wheels or buy the custom made weights? Why on either answer. I plan to make a scale trail truck with a nice trail in the yard.
