Just and FYI, if you look at the attached photo you'll see chips in the outer edge of the openings behind the front wheels. I do use DBK's screens (great product), but I do also track my car and remove them for that purpose.

I just installed a small rubber u-channel that I purchased from MacMaster Carr (part# 8510K11) I bought 10', which was enough to do both sides with plenty left over incase I have to redo one. A little work to get on, but not horrible. It seems to lock in good. I'm not sure how they'll hang on yet when on a track with no screens.

I love MacMaster Carr! I buy lots of grommets & stuff from them for my vintage motorcycle rebuilds.

Has anyone determined that the screens decrease airflow enough to affect track performance? I know DBK’s attorney told him to include that disclaimer, but do they really make a difference? It is like the first instruction in every maintenance manual ever written for every procedure....complete the sentence.

I would think a non factor. I would think you would need to be close to "10 10th's" for there to be any difference in down force. I would probably take them off for speeds over ~150 (mile type event)
