I was driving straight mile events and experiencing some unusual drift from the car. I talked to a lot of people at the track and researched some of the faster cars. I decided to create my own under body aero kit. I'm no engineer, but figured this may help, and it did. Down the track at 202.2 it felt solid.
I started out using cardboard templates, and then transferred it to some dibond sign material. Its basically a stack of aluminum, plastic, aluminum. Easy to cut, shape, and install.
It starts in the front tucked into the lip and is 3 pieces that eventually curl up under my rear bumper to create a rear fin.
I've thought about doing this as well, but had no idea how to go about it lol. I was imagining you'd have to run it all the way across the bottom of the car, but I guess just blocking off the tunnel works enough huh? That should make it much easier.
I removed the shields on the bottom of the cars years ago and never put them back on. I never understood their benefit, but it seems like this was it. I thought it was for keeping debris out of the open areas under the car.
