Wow used my 13.5 stock motor b4.1 in the mod class finished 5th, was running with the best of the best at my track. The losi springs that wild charry recommended are so great i dont remember the fronts but pink rears a good, may try a tad stiffer the hole car was planted and jumped good.

Were I really noticed the change was in the moble section were my car use to bounce it now floats over Def upgrade.

I would like to try the short pack has anybody has success?
