Large vents in the front fenders seem to help a bit but I won't know for sure until I take it to a race track. The rear wing is almost necessary above 120, and can be felt as low as 50-60mph. I've also trimmed up the rear fenders to help them air out a bit as well.

How did you decide to put the vents there, vs. like along the rear near the bottom of the fender, or the middle or ? Just wondering if you did some pressure readings in the fender beforehand or if this is a known trapped area of air along the inside near where the fender bolts to the body.

I ordered a punch and flare tool to do some holes on the fenders on my bug (autocross car).
