Hi abyrd,....I think it will be a much better idea to go with a clear bra because the leather ones could scratch your paint when dirt collects under it and when it moves around at high speeds.
Since you are in California, check out the guys at Premier Mobile. They're very good with clear bras and are very reputable with the exotic cars. Check out this link of recent Elise examples.

They worked on my Elise recently and comes highly recommended. Hope you find what you need.
