I had a friend ask me a question and I was not sure how to answer. I know because of the boat tail we really needed one on the coupe. Heck Audi had to put a fixed one on all the TT's due to stability issues in the field.

The question that was raised was if the Crossfire Roadster needed one. It does not have a boat tail design with the top up or down. I answered that it probably helps with downforce but looking at it I also wonder if they could have skipped it... Anyone have a good responce for this?

Thanks,
