The best fitting vented fenders.
He's got a thread on it. I've looked into doing this myself for many reasons. The first body shop wouldn't give me a quote saying
"If you can buy aftermarket fenders that are the look you want it is very likely to be more cost effective to go that route vs. us fabricating a stock fender".
I just can't get over paying 750-1k plus shipping for aftermarket ones that I would want painted to match on top of that. Getting them to fit right can be another rabbit hole. Not to mention having my oem ones sitting around after the fact. This is a major reason I went with the trackspec hood vents instead of buying an expensive vented hood that would have been form over function.
