- Hey, Wake up out there!! How's this for a thread start: Joe Alexander and Jack Drews both have TR4's with similar but not quite identical preparation. Joe's is a roadster. Jack's is raced with the wi

- While Joe's car has a smaller frontal area, in my unscientific experience, top down TR's are LESS aerodynamic than your car with the hardtop. This observation has been made over many years and many

- The drag due to the larger frontal area of the hardtop is probably about equal to the drag caused by turbulence around the open cockpit of the roadster. If I remember correctly, an MGBGT is slightly

- At the risk of treading on more informed toes, I think without benefit of a full tonneau cover, the car without the top suffers from a significant low (or perhaps high, I don't remember this too well

- Don't down rate your "unscientific experience". Your obversations about a convertible with the top up and top down are exactly correct and based on accepted principles of aerodyanmics. It is one of

- Further confirmation from my experience at Savannah a few years ago. I had my Giulietta Sprint there being co-driven in the enduro by a Giulietta Spider Veloce racer. He had more HP and less frontal
