Mike, I might do that to keep air from catching the bodywork from underneath. Would you use 060 aluminum?

I'll try and get a picture tonight if I remember.
I used pretty thin material and then bent an edge on it to make it stronger.

It looks like .030.
Now that's some fancy welding. I wish I was half that good .
Me too, that's why I had this guy do it .
Measure twice, cut once. Then undo the changes you made
Going back to the original door length will allow access to "cubbies" behind the seats.

Side skirts widened by about 50mm. Aluminum sheet support plus a small welded plate at the rear for additional stability at the rear intake.

Mounting door outer panel to door frame. Had the fiberglass shop that did my hood and rear spoiler throw together some fiberglass "angle iron". Bonded to door skin, rivets to the door frame.

More fiberglass work to match the window seal contour at the rear of the door, aluminum template for layup.

Fitting the door card, donor upper but will require fabbing lower part to clear the cage/side bars.

Boxing in the side coolant pipes. Made 2 temples. Started with a flush top which looked really nice. Then I figured I would incorporate the door seal into the piece.

Final design, should be a nice door seal with the weatherstrip.

I love your attention to detail, as well as the patience that you have building this car. I haven't even had mine a year, and I struggle at times with how long I foresee it taking to complete my car.

Wow.....what an incredible amount of work you've put into that! Looks like it's coming along pretty nicely!

Passenger side was the prototype, made great progress on the driver's side last night and today. Symmetry is the ultimate challenge here, especially starting with the asymmetric GTM body.20241213_123221.jpg20241213_123242.jpg20241214_143411.jpg

Driver's door bodywork nearly done.
Was considering options for license plate mounting with the center exit exhaust, including below one of the taillights. Will mount it above the diffuser. Ordered diffuser strut mounts to finalize diffuser location. As it sits, diffuser angle is 18 degrees which is on the high end but I think it will be functional with the spoiler assisting it.

Finished the passenger side rear trunk. Tons of storage space back there. Need to order more 040 aluminum to do the driver's side.

Really cool engineering as always. Do you have a rendering of what you expect the car to look like when done?

Hey beeman. Looking at the rear picture you have there...don't mean to be negative or anything...but in my experience with these cars, you are going to need a lot more ability to evacuate hot air out the back of the car than what you have there. I understand that this is just work in progress shots and maybe you have a plan. Just trying to give you a heads up before you are too far down a particular path.
Mike- I'm hoping that my setup won't have significant heat issues. I'm going to use Shane's aluminum vented aluminum hatch insert instead of the supplied glass. I will have venting above the resonators on my rear trunk panel as well to help the exhaust heat to escape. I'm also dropping the diffuser which will open the rear quite a bit. I'm a NA 525hp so I'm not pushing the limits with forced induction, etc. What do you think?
I did one back in 2017 (holy cow), but quite a few changes since.

Working on finishing the bodywork, found my way around to the engine air intake. Started analog with paper and Styrofoam, then realized that I will be making a mirror image on the passenger side (fresh air into the engine bay vs oil cooler) because it's going to look lopsided if I only put a snorkel on one side. So off to CAD, a bit rusty, can't remember the last time I used it. I'm using the existing Lamborghini Evo style intake that I drew up previously, now I need to duct that intake to the GTM body at the rear 1/4 window which feeds my airbox. The body has compound curves in this area, so I'm not going to be able to print something that will be perfectly formed to the body ( I don't have a 3D scanner). So I drew up a duct, will print it, and will blend it to the body and make a fiberglass part. Printing will help keep the driver and passenger sides symmetric.

Abandoned the paper and foam pretty quickly...
20241228_190351.jpg20241228_190934.jpg
New transition part between snorkel and body, the 2 parts will mate together to make 1 part

Again, loosely based on the Lamborghini Huracán GT3 EVO2

About a year ago I started on the same task for my 818, scoops for the 1/4 windows to feed air box. I got 2 revs printed and test fit before I had to shelve the 818 for a few years. Hopefully you finish before I resume and I can improve my design based on your work
