I realize that there are some dimensions around the roof area that are different from the stock Mustang and the Supercars Mustang, but I feel its not major enough to not attempt to make a good looking model out of it.
The major difference is the nose, its simple completely different on the Supercar.
With basically no dimensions I started to sculpt out the front nose, little-by-little
I did weeks of filling, and sanding, over and over, until I got the basic shape.
New Hood, Nose, Grill, splitter, and rear wing assembly
Also a right-hand drive setup for the inside
After I got all the parts scratch built and perfected, I made molds and cast them with resin.
The one part I need help on was with the wheels, I tried to scratch build them by hand but it just wasn't looking good. So I asked my good friend Indycals https://www.indycals.net/ for help! He 3D drew the wheels up and had them printed by Shapeways and the LOOK AMAZING! Thank you Indycals. Also, Indycals will be offering the decals for this new Resin conversion kit.
I will make a mold of these 3D printed masters and cast them in resin.
The modifications for this new conversion kit will actually be pretty basic
Some sawing on the front fenders, and cutting out the hood is the most work this kit will require. There will be some filling and sanding for sure, but that's no big deal.
More updates, coming soon.
In the meantime feel free to check out my new and improved website (Formulaly known as Hobbitime)

That's why the shape is so off. All Supercars are build on the same "chassis" which was designed for a 4 door saloon (Falcon/Commodore/Altima/...). So they had to wrap a 2 door exterior on a 4 door one, hence the somewhat weird shape of these cars. You will never get the exact shape from a real Mustang though as they are too different.
