RE: associated SC10 brushless rtr
If you are about to purchase a kit then you should just go with a Factory Team 4x4 IMO. Compared to the others you already have your sway bars, saddle pack battery tray (better center of gravity), Titanium turnbuckles, majority of the screws are aluminum (and blue PIMP!!), and a Carbon fiber chassis brace (helps the roll). I have a SC10 4x4 and I wished I just had waited for it to come out.
