The SEMA show is all about competing for attention from crowds and media inundated with stimulation from the show floor. From elaborate booths and presentations to seas of project cars and thousands of new products, there’s a lot for gear heads to take in. CGS Performance is no stranger to the SEMA project car game, so the company knew it had to push the envelope with its second Mustang project in as many years.

“Ford asked us to develop some new products for the new EcoBoost Mustang and at the same time we decided to build a project vehicle out of our car,” CGS Performance Products President Casey Scranton explained.

A Different Path

Having been down the SEMA path before with its wild, solid-axle Mustang GT, CGS took a different approach by starting with an EcoBoost convertible. While its predecessor had really wide wheels out back, this car went wide all the way around but maintained the factory independent rear suspension.

“We wanted to show people that the EcoBoost can still be cool and get up and go with over 400 horsepower,” Casey said.

The interior of the latest Mustangs is a major upgrade over the previous models, but Alea Leather took the guts of the CGS SEMA ’Stang to a whole new level with red Napa leather on almost every surface. The floor mats are from Lloyd Mats and the safety belts are from Seat Belt Planet. While the engine is stock, the CGS EcoBoost project does benefit from the company’s cat-back exhaust.

While CGS relied on other aftermarket manufacturers like Kompression, Pirelli, Steeda and Whipple for this build, the company also developed some of its own new gear for the EcoBoost platform.

“CGS now has an EcoBoost cat-back exhaust and we are working on a cold air intake for it now,” Casey explained.

While there’s a smattering of performance goodies on this convertible, the project was clearly about creating more aggressive styling. At the time of its release the 2015 Mustang was wild, but it has suddenly become the norm. However, there’s nothing ordinary about CGS’ TS Design-widened convertible. Now the company has two wild S550s in its stable which they take on tour to events events across the country in the company’s big rig.

The Sister Car

If the name CGS Performance sounds familiar, it’s not just because of the company’s exhaust line. You probably remember the company’s groundbreaking widebody Mustang, which took its first bow at the SEMA show back in 2015.

Wearing a striking red finish over widened bodywork, it was powered by a Whipple-supercharged Coyote putting down over 700 horsepower at the wheels. It was also the first ever S550 to receive a solid-axle conversion.

Casey and the CGS team worked with Chris Alston Chassisworks to develop a new rear subframe that allowed for installing a Chris Alston’s Chassisworks Fab9 rearend filled with Strange Engineering ST axles and a Strange Engineering differential.

What really makes this car stand out, however, is that the rearend was narrowed and the body widened to allow for the installation of massive, 24×16-inch Kompression Forged wheels and 405/25-R24 Pirelli tires.

With two cool Mustangs under its belt, CGS Performance isn’t slowing down on the project vehicle front. It hopes to have yet another vehicle new in Las Vegas in the future. For now, however, the company can enjoy two unique and different S550s.
