ya its all cracked cause i found it at the junk yard, and any downforce haha ill need it in the front cause i want a spoiler :drool5
the kit itself is designed to mock the imsa car. which it does fairly well. the side skirts reduce drag. any side skirt that isn't crazy looking tend to. the front bumper doesn't creat any downforce at all. but it does channel air much better than the stock lip. the rear bumper really needs to be modded (similar to mine) to eliminate the drag caused by it. i hope that is a good start for ya.
