At the SEMA Show, Ringbrothers debuted "Billie," a meticulously crafted 1965 Pontiac GTO Convertible. This extraordinary custom build, originally a Pontiac Tempest Convertible, is the result of over 5,500 hours of dedicated work, culminating in a vehicle that boasts 650 horsepower. The transformation involved significant body modifications, including a five-inch widening, alongside the strategic integration of lightweight carbon fiber elements. Under the hood, a potent supercharged 6.2-liter LT4 V8 engine provides formidable power, paired with a sophisticated 10-speed automatic transmission. Inside, the GTO features a bespoke cabin that marries vintage charm with modern conveniences. This project stands as a testament to Ringbrothers' commitment to blending classic automotive design with cutting-edge performance and custom craftsmanship.
Extensive Exterior and Performance Upgrades
The Ringbrothers' 1965 Pontiac GTO Convertible, codenamed "Billie," represents a monumental custom automotive project, showcasing extensive modifications and a formidable powertrain. Starting from a Pontiac Tempest Convertible, the team invested more than 5,500 hours to meticulously widen the body by five inches, ensuring the classic proportions of the '65 GTO were not only preserved but enhanced. This intricate process involved reshaping the front fenders, elongating the rocker panels, and broadening the rear quarters. The co-founder, Jim Ring, emphasized the challenge of subtly integrating these changes to make them appear factory-designed. The exterior is further distinguished by significant use of carbon fiber, including the hood with an enlarged scoop and functional vents, front wheel tubs, lower front valance, and rear diffuser, all contributing to both weight reduction and aesthetic appeal. Custom bumpers, redesigned headlight surrounds, and a unique one-piece aluminum taillight panel, complemented by a striking custom Billie Goat Blue finish with polished chrome accents, complete the exterior transformation, underscoring a blend of classic design and modern high-performance elements.
Beneath its stunning exterior, the GTO is equipped with a supercharged 6.2-liter LT4 V8 engine sourced from Wegner Motorsports, an engine renowned for its power in various General Motors models, such as the Cadillac CT5-V Blackwing. This powerplant delivers an impressive 650 horsepower and 650 pound-feet of torque, channeled through a Bowler Performance 10-speed automatic transmission for seamless power delivery. The vehicle's performance is further augmented by a custom exhaust system featuring Flowmaster components, enhancing its auditory presence. To manage this immense power, the GTO incorporates Fox RS SV coilovers and a Fast Track Stage III chassis, providing superior handling and ride dynamics. Braking duties are handled by high-performance Brembo brakes, fitted with six-piston calipers at both the front and rear, ensuring exceptional stopping power. The car rides on staggered 19- and 20-inch HRE G-code wheels, wrapped in Michelin Pilot Sport Cup 2 tires, combining aggressive aesthetics with optimal grip and performance. This comprehensive suite of modifications transforms the classic Pontiac into a modern performance marvel, capable of dominating both the show floor and the road.
Luxurious and Technologically Advanced Interior
The interior of the Ringbrothers' custom 1965 Pontiac GTO Convertible, "Billie," received a comprehensive overhaul, blending classic design with modern functionality and comfort. The team meticulously reconfigured the cabin by repositioning the dashboard four inches forward and two inches lower, optimizing both aesthetics and ergonomics. This redesigned dash features custom aluminum trim, adding a touch of bespoke luxury. State-of-the-art Dakota Digital instruments replace the original gauges, offering precise and clear readings while maintaining a classic look. For enhanced comfort and convenience, Vintage Air climate controls have been integrated, allowing occupants to easily regulate the cabin temperature. A modern auto-dimming rearview mirror improves visibility and reduces glare. These thoughtful upgrades ensure that the interior is not only visually appealing but also highly functional for contemporary driving. The addition of a "Raised by Ringbrothers" plaque on the dash serves as a subtle yet significant emblem of the car's unique heritage and meticulous craftsmanship.
Further enhancing the driving experience, the vehicle features a restored factory radio that has been upgraded with modern Bluetooth connectivity. This ingenious modification allows the driver to enjoy contemporary audio streaming and hands-free communication while preserving the authentic vintage appearance of the dashboard. Every aspect of the interior, from the choice of materials to the integration of technology, reflects Ringbrothers' commitment to delivering a premium and cohesive experience. The custom touches extend throughout the cabin, creating an environment that is both luxurious and practical. The combination of classic styling with discreetly integrated modern amenities ensures that "Billie" offers a comfortable and engaging interior, making it a truly exceptional custom build. The extensive work on the interior underscores the thoroughness of the Ringbrothers' approach, where no detail is too small to be perfected, resulting in a GTO that is as captivating inside as it is on the outside.
