Factory Five Racing (FFR) was started in 1995 by the car-crazy Smith brothers, Dave, 31, and Mark, 32. We've all heard of dreamers losing their minds and their worldly goods trying to build cars -- even kit cars -- but the combined backgrounds of these brothers -- in business, engineering, and manufacturing -- brought a discriminating and more cautious quality to the often tumultuous business of making cars. They've been successful from the git-go and today sell about 550 kits a year. Since there is no national kit-car association, industry statistics are virtually nil, but Jim Youngs, editor of Kit Car magazine, says the Smith brothers sell more kit cars than anybody else.
