DIY: Functional INGS fender vents

[Deighvid]

There's like 10 people in the US that have INGS fenders/kit and maybe 5 online lol so not a whole lot of documentation

I decided to share some measurements I made and methodology I used in deciding how to cut my fender-liner so that the fender vents are functional. Yes, this is probably way over-engineered but whatever. lol

Tools:
paint marker
measuring tape
1/2in drill bit
Dremel with sanding barrel

Methodology:
I didn't want to just cut giant holes and expose too much of the area behind the fender, considering that the vents aren't that deep and there are various wires and things, so I started by making some measurements to identify a conservative safe area to cut, leaving room to expand if needed. I also opted to drill holes instead of cutting slits, to retain structural integrity. I track this car and I don't need the fender-liner flapping around and/or ripping off.

Also, it's worth noting that the passenger side area has a big ass washer fluid bottle in the way (which I documented in the photos below) due to this, you have to cut a little more conservatively. I wanted both sides to match as best possible, so I first mapped out where I would drill/cut on the passenger side and then more or less copied it on the driver's side (even though there's way more room available)

When I searched the internet I couldn't find a single helpful post or video about how to properly cut for these vents, so at the very least I hope that this serves as a good place to start when doing yours

Let me know what you think!

Some additional notes:

-There was method to the madness of how I drilled the holes and how the outermost left and right rows are offset slightly.

-Take care to not drill the holes too close together so they don't rip into each other.

-I went over the outli es a bit, but that's why the outlines/measurements were done conservatively so I knew there was a bit of wiggle room.

-I may take black gaffer's tape and cover/protect some of the wires that run behind these openings depending on how close they are once I put the liner back on the car.

Do you want air coming through, from an aero point of view? Usually we want the wheel wells sealed unless going full race car with no lines and vents on top of arch.
Or does the Supra have different needs?

Pressure needs to release from the wheel wells so this helps with that. Same for the vents you see cut in the hood above the wheels, and fenders like EVS that are huge cutaways

I see. I figured this would introduce pressure seeing how it's coming from air forced from front. I thought we usually vent rear or top.
Good stuff. Carry on ?

Yeah, on the Supra you usually see front vented a majority of the time since there so many solutions to do so, and/or the rear if either the rear bumper is cut like on @JackieD86 car, or if the body kit has built in vents.
