I don't buy that either. That area would have a low pressure void at speed so removing the panel IMHO would not really affect downforce. It think that panel is more or less cosmetic and a place to hold the license plate I don't see how it could severely disrupt exiting air if you remove the panel. I just looks unfinished and kinda funky.Jay said:on the Federal Elise its not a good idea to remove the rear diffuser or the panel behind it that looks like it blocks air flow. Per Tony Shute (at the LA show) the area is designed that way and removal will lessen downforce. and do nothing for cooling or anything else other thatn change cosmetics.
I figure if the Lotus engineers couldn't figure out a way to remove a part, it has a purpose.
