300-03If you have had the pleasure of meeting Juan Rosales in person you know what he is passionate about. His family and his laid out 2005 Chrysler 300c dubbed “Low300c” as shown in his California personalized plate. It all started when Juan first laid eyes on the overhauled Chrysler 300c model and he immediately traded in his old ride and has never looked back. Juan has poured his heart and soul into this build and it shows throughout – to say this is a “show car” from top to bottom would be an understatement. What show car do you know that is this detailed and is still driven to shows? Not many, we can assure you of that. Juan’s 300c is built like a trailer queen, yet never sees the trailer, which is our idea of the “perfect” build.

Having previously built a 1972 Dodge Dart Juan knows his way around the Mopar family. Six years ago Juan embarked on what would become an epic journey to build this beauty you see on the screen before you. After he lost his first 300c in an accident, he knew that his full potential had not peaked with the previous build. He made the decision to buy another 2005 model and within five months had already debuted it at the Forbidden Fantasy car show. Since then, this car has went thru a total of three iterations and was even featured at the SEMA show twice before.

To acquire the ultra low look Juan was after, the suspension was upgraded to Universal Air with strut bags in the front and bellow ‘bags in the rear, Viair 444 compressors keep the air flowing as needed and a Specialty Suspension 18-inch polished tank was used for air storage. To help smooth things out even more, a set of Bilstein SRT8 shocks keep the long road trips to shows comfortable. A recurring theme of this build is that it will never be finished and Juan continues to reinforce this thought process by going further than what the normal show goer will see. The entire front and rear suspension has been chromed, polished, or powder coated. In order to fit those massive 24×9 and 24×10-inch Raceline Explosion 5 wheels, Juan called upon Art Gomez at GoEZ Customs to cut and tub the wheel wells. Toyo Proxes 275/25/24 tires were used at all four corners along with R1 Concepts custom engraved rotors and polished calipers. The overall stance of the car is on point with the combination of detail work, suspension work, and killer wheel/tire setup.

The exterior of the car is really set apart by the use of a 2008 Dodge Magnum SRT8 front clip. Body mods include shaved door handles, fuel door, hood squirters and trunk emblems. Additionally, a Classic Design Concepts Glassback roof was added to really put this 300c in a category all its own. Once the House of Kolor Tangelo paint was laid down and the pinstriping by Duran’s Quality Paint the car began to look like it might actually be “finished” this time around.


However, moving to the interior there is no OEM piece left untouched. Joe Comacho at California Upholstery was called upon for the job. The headrests were deleted from the seats before they were wrapped in custom leather. The rear seats were reshaped into buckets with a custom center console and the dash was also smoothed and upholstered – you would be able to use something like this handheld vacuum to help keep your car’s interior tidy. A custom 15-inch Raceline billet steering wheel was added that includes a custom polished hub adapter. The gauges feature a stainless steel gauge cover to continue the classic hot rod styling throughout the cabin. Other details include; polished aluminum pedals, chromed seat frames, Billet Technology polished billet covers, Acrylic Conceptions Switch Panel, Modified Metal custom polished shifter and color matched plastic trim throughout. You seriously need to see this ride in person to fully appreciate all of the custom details. A SoundStream double-din head unit controls the audio system, while Kicker mids and highs keep the tunes pumping for the road trips to shows both near and far.


The engine bay and motor is the latest addition and an absolute work of art in Juan’s ride. SRT John performed the necessary mods to increase the horsepower on the 5.7L Hemi. The list of mods and appearance updates include; SRT polished manifold swap, chromed hood hinges including billet shocks, Killerglass radiator hose, stainless steel hoses, polished firewall, chromed ABS cover, polished and powder coated strut bar, Billet Technology polished billet caps and catch can with hardline. A Nag1 custom-built transmission was married to the Hemi and an Airraid air intake with custom orange filter keep the motor breathing cleanly. Magnaflow high flow cats and catback exhaust round out the mods to this highly detailed motor and engine bay.


Juan’s advice to everyone out there building a vehicle from the ground up is simply “Do it right the first time, it’s much cheaper that way.” Fixing mistakes or redoing a build over and over again costs an exorbitant amount of time and money. His motivation comes from his Mopar buddies and he really enjoys being able to drive his car to various shows and to have the respect of so many different sub sets of the scene that we all enjoy. Thanks goes out to his many sponsors whom helped along the way including: Raceline Wheels, Toyo Tires, Magnaflow Exhaust, Airaid Intakes, R1 Concepts, Viair, American Car Craft, Toro Wax, Amsoil, Odyssey Batteries, Slam Specialties, Killerglass, Acrylic Conceptions, and Modified Metal.
