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.
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.
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!

Luckily I have other projects that I can bounce around on when I need a break. My GTM is by far 10x the work compared to the other car projects I have... But I think it will be my favorite when it's done.
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.
Wow....you're going to have a ton of storage space there!

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. jwxrtbi7.jpg
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.

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
Sorry the quote function is not working, but back to post 862...I ran a 525 LS3 for quite some time and it needed all the air evac I could get. I too have gone over to Shane's aluminum rear window and it works very well. Lots of air can move through that insert. HOWEVER, we did a string test to see how air is actually moving out of that louvered rear insert and you might be surprised that air is actually moving INTO the engine compartment and very little is moving out with that insert. Of course we have the entire rear of the car open for air flow so it might be different than what you have there. You can always cut it open later. That's what we did as we developed the race car. It started with everything intact and then went to more air flow as needed. Closing up the floor behind the driver and under the engine area really boosted the requirements for more air evac from the engine area. I also have wrapped the exhaust in four layers of Lava Wrap. We closed in the 1/4 panel vents after the fire where the driver got his suite singed by the flames that came forward out those vents. Probably not as big an issue if you are using those vents with a sealed connection to the engine intake. My suggestion is to leave the rear how you have it and just be prepared to open it up when/if it is needed. Maybe keep this in mind when building body supports and such.
Crash.....yeah, that makes sense if you have a really effective path somewhere for air to be drawn out of the engine bay....that it would be drawing air into that louvered window replacement panel. As you said, whether that panel draws air/heat out, or allowed fresh air in is going to depend on what other methods you're using to both get fresh air in and draw air out. If you install that panel on a car that has our diffuser louvers installed, I would fully expect for those louvers to have more "pull" than the hatch area.....so air would flow toward the diffuser. On cars without the diffuser louvers and a good path for air to be forced into the engine bay, I would expect that the heat/air would flow out of the hatch panel.
