To create big suspension travel while maintaining a sensible track width, the control-arm mounts are placed far inboard. "This chassis is the sister truck to the Pro-4 F-150 that Nye Frank built for Rob MacCachren," Evan reveals. As originally configured, the forward control-arm mounts were so far to the front that they actually limited the turning radius. Evan pulled the mounts back a bit so that his truck could negotiate sharper curves. Since Evan plans to jump into the Pro-4 wars in future seasons, this truck will serve as a jumping-off point when fabrication begins. The current field of Pro-4 competitors is fairly narrow, although deeply laden with talented drivers such as Curt LeDuc and Carl Renezeder. There's clearly room for fast guys like Evan Evans to jump into the Pro-4 fray. Why bother with Pro-4? Simple. It's the premier CORR class.
