The 8xl isn't being maximized with the low cell count(although it would perform very well just the same). For pure speed on 14 cells, I would think about the xl3600. This would be a rocketship. For tires, you may consider what LiPomaxx is doing - 1/8 buggy tire conversion. This would minimize the rotating mass, resulting in increased aceleration and runtimes.For road running, 4 shocks will be fine. Just use a stiff srping and heavy oil. The panther komodo tires are a nice, small, light tire as well, but they would wear out on the street pretty quickly.
