If you are looking at some nice black rims for that Lotus, you may want to check out this web site.

These are the best looking wheels for that car in my opinion. They also have allot of performance mods on this site for the Lotus. I did some research on the Lotus and I am also considering it for my next car if I ever sell my Boxster. The front bumber is removable from the rest of the body. They make a complete Carbon Fiber front end as an option for racing, not street legal, but who really would know if it was painted.
Aslo, there aren't many types of rims availible for the Lotus because it uses only 4 lug nuts. I did not like the stock rims and that's how I found these. Good luck and beware of speed bumps and pot holes.
