Roush and Saleen are the largest known aftermarket Mustang companies known to date. But one I've always been fond is Steeda Autosports, they are starting to make a big wave in the Mustang world. One of their projects was the yellow 2005 Ford Mustang GT Coupe Premium. Everything from the chrome rims to the custom spoiler in back are very unique. Steeda has done a great job with the custom Mustang muscle car. Here's a rundown of list of modifications for the Steeda Mustangs:

I don't think I ever mentioned the super snake package Shelby offers for the Shelby GT500 Mustang. It's so much horsepower it even beats out the Shelby GT500 KR. The super snake package shoots the horsepower of the GT500 up to 725hp. Other modifications include an even more aggressive suspension and braking system. I sure do love the color scheme on this Shelby GT500, the gun metal gray looks sick. Along with the chrome and black racing stripes, this is one bad ass Mustang!

This is one clean Ford Mustang, before your eyes is a 2009 Roush 427R Mustang. I got this beautiful shot of the Jack Roush Mustang at the Woodward Dream cruise last year. It sure is a wonderful looking aftermarket Mustang. Every little modification by Jack Roush is pretty sweet, the chrome five spoke wheels look great. The big hood scoop, ducktail fin spoiler, and the cool ground effects.

This is one of my favorite pictures of a cool custom Saleen Ford Mustang. The front shot showing of the hood with the vents is very cool. The Saleen Mustang is one of my favorite aftermarket Mustangs ever built. This Saleen Mustang picture can make a great wallpaper for your desktop background.

Checkout this awesome concept of a Mustang.  I think this is a photoshopped picture of a Mustang or it might be the video game Forza Motorsport.  Whatever the Mustang is from, it's sure one hell of a muscle car.  I love the side pipes and the huge bumper in front.  The white racing stripes down the middle look great too!

This picture is just beautiful, great shot of a 1970 Boss Ford Mustang.  Sporting a awesome orange and flat black paint job.  The rims on this year are pretty cool too, gotta love the massive hood scoop as well.  Anyone a big back window louver fan?  They just looked cool as hell on this model year Mustang.

This custom Mustang was designed by Chip Foose and Unique Performance, they made the custom Ford Mustang for BFGoodrich to showcase around the world. The custom Foose Mustang uses only the best street tires: BFGoodrich g-Force tires. Everything about the car is sick! I love the billet grille up front, the massive hood scoop, and the custom Foose wheels.  I usually don't like two tone Mustangs, but for this Mustang I'll make an exception.  The sunset orange paint job goes sweet with the black pain job up top, instant classic!

Checkout this picture of another fugly Ford Mustang. I think this by far beats the custom black Ford Mustang was showcased at the SEMA show last year.  Nothing on the Mustang resembles a muscle car, it almost looks like a the new Nissan Skyline GT-R. Except the Nissan GT-R looks better than this, this is down right hideous looking. Too much on the Mustang was squared off. The spoiler out back and the hood scoops on top of the roof need to go.

This has to be one of the coolest custom Mustangs I have ever seen. Got to love the hot body flaunting next to it as well. Both of these vehicles were custom designed by O'meara Custom Designs, Mike Magree. A Ford Mustang Gt and a Ford Yeti F650. I like how they dressed up as a cop and made it look like she was pulling over the custom Mustang, now that is hot. I would love to see here try to get out of the Yeti F650.

Checkout this beautiful drawing of custom Ford Mustang, it's just gorgeous.  Every now and then I get emails of fan work, this drawing of a Mustang was done by a fan out of New York.  I must say he has great taste in Mustangs.  I've never seen a Mustang with straight laced door panels before, it looks pretty cool.  And the hood scoops up top are very aggressive looking, which helps define the muscle car Mustang.  The deep dish wheels are nice choice as well!  This custom Mustang was an instant hit with me!
