To more like that

I don't think you will get much benefit, considering how shallow the rear window already is. It will just be a lot of effort to create an ugly vehicle.

How about getting rid of those fake air intakes on the sides and removing the spoiler?

your rear spoiler is already compensating for the roofline.I agree with wink,that you'll gain very little for all the trouble.
If you're very curious,create a one-shot mockup of the fastback out of cardboard and tape and test to see if theirs a significant difference.

Do it nice and it'll look cool :thumbup:

He'll never match the Ford "edge" styling, much less make it look decent, because he's not an auto body professional. Look at basjoos's Civic. It looks like someone pasted Play-Doh all over it.

My advice would be to work on the underside. A good undertray will give you FAR more benefits than a fastback mod would, especially with your already smooth rear window.

One way you can improve topside aero is remove the spoiler and install the fin-shaped radio antenna you see on BMWs and such, which doubles as a vortex generator. That spoiler's design will give rear downforce unlike the strictly cosmetic ones, so removing it will make the rear end feel loose on the freeway. You'll need to weigh the pros and cons on that for yourself.

Also, seeing how aftermarket Mustang parts are so common, go with a set of lowering springs.

All I'm saying is that if it's done nice the fastback styling looks good on that body. Workmanship is another matter... so is fe gain.

Took the spoiler off, so far very little gain, maybe .25mpg.
I am going to lower it tomorrow or so.
I've been toying around with the underside, but just can't make up my mind on what materials to use, coroplast or plastic or 20 gauge aluminum.

The reason I was thinking about doing a fast back conversion is to get closer to 13deg angle and they never made fast back so it'd be different for sure.

Lowering is a drastic step for aerodynamics. You're hugely limiting slopes you can drive up, increasing chance of hitting the underside on speed bumps, objects, etc.

What about an air dam?

After reading up here I thought the same thing about these cars. What about
bringing the roofline out even with the bumper, sorta a Daytona coupe effect.

Visually the idea is a winner ! Good luck whatever you do.
