Came across Racesills online for the Lotus Elise, they look pretty interesting. Does anyone have any personal experience with racesills or ground effects on their car and noticed any drag reduction and increased down-forces? Would be nice seeing real numbers from a wind chamber comparison with/without. I could see these sills calming and reducing choppy at the lower sides and outer edges / underside of the Roadster. Aluminum and Carbon Fiber ones are available for the Elise/Exige. They may just work for the Roadster as well. They also add a second function as to protect the rocker area from rocks that get kicked up from the front wheels. Also would help keep rocks and crud getting up inside your Roadster's doors in the winter/rainy months.
