That's one of the best looking homemade fender of that style I have seen.

A few updates. I've gotten both sides to this stage finally. Does anyone have any recommendations on resources to have these reproduced? I wouldnt mind sending them out, i've been getting a lot of interest on these dive fenders.

N/P. It's such nice fab work, I figured you'd want some legitimacy when someone who may have some aero knowledge is checking your stuff out, knows you know too!

Wow, thank you for that info. I am going to look into this, I would love for it to be more functional. I did however set a piece of abs angled behind the arch to help reduce high pressure air in the wheel well. But it is still in design so im going to do a little more research on how to make this more functional on the track.Originally posted by 2GRX7 View PostVery nice! Dive planes have a couple of purposes with first, obliviously, helping create front-end downforce, but they also help create a low pressure zone at the wheel, allowing brake heat dissipation, and radiator/intercooler heat evacuation (if designed to do so).
Consider moving the dive planes up to where the trailing edge (when looking from the side view) is along the same plane (equal height) as the top of the rim).
You could create a diffuser that spans the wheel well to the outside edge of the splitter. It will give you more consistent downforce as the dive planes can be pitch-sensitive and leave you hanging in a braking situation.

Here's a pic of the fender. It's just tacked in place going to clean up the welds and grind more to get it smooth
