The only two I'm aware of is the factory and HK Fevers and neither are painted. You may be able to get HK Fever to paint them for you. I'd worry that it wouldn't match. I know a few owners here have had it panted themselves.
Look at the HK thread. Someone posted the original part numbers there. Once you have them, you can check if they are readily available. However, more than likely, not given they were lotus motorsports parts.
