It came up that a hardtop designed for the Elise should work on the Roadster as well. The soft tops are already identical, and a "short" Elise hardtop would sit the same way... extending only to the front of the roll bar. The Roadster hardtops extend over the carbon fiber (CF) roll bar so that so that the body color doesn't get broken up with a dark band in the middle. But that wouldn't be an issue with a CF top that should blend in with the Roadster roll bar. I suppose there could be an issue with the pitch of the CF weave not quite matching. Also the Elise hardtops have this styling/aero notch that Roadster owners might not like. Still, it would be interesting to see someone try it. Here are a few aftermarket Elise CF hardtops I found with a quick web search: Elise Parts - *>**>*S2 Elise "Short" Hardtop Elise CF Hard Top - Sector111 aftermarket parts for Lotus RevoZport Racing Technology Ltd.
