Mitch Yelverton over at The Truth About Cars has a brief history of late-Sixties/early-Seventies downforce packages and their consequences re: the future of Formula 1 motorsport competition. And guess what? It involves Colin Chapman. Interestingly, there's no mention of Texas Jim Hall, without whom no discussion of downforce can be complete. We're off to go build a sucker car now. Anyone got a spare snowmobile engine we can borrow? Thanks.
