The set-up it comes with is what Travis Amezcua uses. It's the same set-up he used to win the nationals. He does change shock oils, shock springs and diff oil.
I think he uses the blue kyosho springs on all fours, and then for diffs i think he goes
He also uses different tires (but thats a given)
Other than that he runs completely stock.
Also, try emailing travis from his address on team losi's site.
