2012 Ginetta G55 GT4 Dimensions, Size & Specs

The Ginetta G55 GT4 has a curb weight of approximately 1085 kg (2393 lbs). This lightweight construction is a key feature of the GT4, emphasizing nimble handling and quick acceleration. The low weight contributes to improved braking distances and enhanced cornering agility, crucial for track racing and spirited driving. The chassis and body panels are made from lightweight materials to keep weight down, allowing the car to maximize power-to-weight ratio despite having a relatively modest engine. This combination of low weight and race-tuned suspension makes the Ginetta G55 GT4 a highly responsive and precise vehicle on the track.

Yes, the Ginetta G55 GT4 fits comfortably in a standard residential garage. Most standard garages measure around 2.4 to 2.7 meters (8 to 9 feet) in width and at least 5.0 meters (16 feet) in length, which are ample to accommodate the Ginetta G55 GT4's compact dimensions. The car, being a low and wide coupe with an estimated width close to 1.9 meters (74.8 inches), leaves sufficient clearance for easy parking and door opening within typical garage dimensions. Its relatively short length also helps in tight urban or residential environments. However, owners should take care when maneuvering due to the car's wide wheel arches and racing aerodynamics.

The Ginetta G55 GT4 features rim sizes of 9J x 18 inches on the front and 10J x 18 inches on the rear, indicating staggered widths which contribute significantly to traction and cornering performance. The wider rear rims (10J) allow for larger rear tires providing better grip during acceleration and stability through high-speed turns, while the slightly narrower front rims (9J) balance steering precision with traction. This setup, combined with the car's approximate width around 1.8 to 1.9 meters (70.9 to 74.8 inches), provides a wide and stable footprint, enhancing lateral grip and overall stability on the track. The alloy wheels and tire combo are optimized for race conditions, balancing tire contact patch and responsiveness.

The Ginetta G55 GT4 is primarily a race car built with a focus on driver performance rather than passenger comfort or spaciousness. As such, its interior is compact and minimal, designed to fit a single occupant or driver and a passenger tightly with racing bucket seats and harnesses. The cockpit layout is optimized for control and visibility with likely limited headroom and legroom due to its low roofline and compact cabin. Measuring precise interior dimensions is challenging as Ginetta often customizes interiors to racing specifications, but expect a snug fit with little excess space, prioritizing weight savings and driver ergonomics over luxury or extra roominess.

Compared to its predecessor, the Ginetta G50, the G55 GT4 shows several refinements in dimensions aimed at improving performance and aerodynamics. While the G50 was a successful model, the G55 GT4 was designed with a slightly more aggressive stance and possibly marginally wider and longer bodywork to improve downforce and stability on the track. The G55 also benefits from advanced suspension and chassis refinements, which often result in changes to track width and wheel dimensions, such as the 9J and 10J x 18 rims setup not found on the G50. Overall, the G55 GT4 focuses on maximizing grip and handling with subtle dimensional increases, while still maintaining a compact, lightweight profile similar to or slightly larger than the G50's dimensions of roughly 4.2 meters length, 1.8 meters width, and a curb weight slightly above 1000 kg.

The Ginetta G55 GT4’s low height, estimated to be between 1.1 and 1.2 meters (43 to 47 inches), significantly contributes to its exceptional handling and stability. By having a low roofline and overall profile, the car achieves a lower center of gravity which minimizes body roll during cornering and enhances weight distribution. This low stance combined with race-tuned suspension ensures the car remains planted under heavy braking and sharp directional changes. Aerodynamically, the low height reduces drag and improves airflow management over the car’s body, also contributing to increased downforce crucial for high-speed stability on race circuits. Overall, the low height is a critical factor in the G55 GT4’s precise and responsive driving dynamics.

Weighing in at approximately 1085 kg (2393 lbs), the Ginetta G55 GT4 is extremely competitive within the GT4 racing class. Cars in this category typically weigh between 1200 and 1350 kg depending on make and modifications, which makes the G55 one of the lighter entries. Its lightweight construction enhances acceleration, cornering speeds, and braking performance, making it a nimble and responsive contender on the track. This low weight, combined with its chassis tuning and aerodynamic design, offers advantages like quicker direction changes and reduced tire wear, helping it to compete aggressively against heavier rivals such as the BMW M4 GT4 or Audi R8 LMS GT4.

Compared to other GT4 class cars like the BMW M4 GT4, Audi R8 LMS GT4, or Porsche Cayman GT4 Clubsport, the Ginetta G55 GT4 stands out with its notable lightweight chassis at around 1085 kg (2393 lbs). Dimensionally, the G55 is somewhat shorter and lower, focused on a compact footprint that improves agility and cornering precision. While its length is roughly 4.2 meters (165 inches), competitors tend to be larger and heavier. The G55’s wheelbase and wide track, aided by its 9J and 10J x 18 inch rims, provide stable high-speed handling but with a stronger emphasis on driver engagement and less electronic aid. Its weight advantage generally offers better acceleration and braking efficiency, although other cars in the GT4 class might excel in top speed or technological features. Overall, the G55 GT4 is a pure, driver-focused car with dimensions optimized for nimble race performance in the GT4 category.

Yes, the Ginetta G55 GT4 is highly adaptable for track customization, including changes in rim sizes and tire widths. The factory setup with 9J x 18 inch front rims and 10J x 18 inch rear rims supports a staggered tire layout designed for maximum grip and handling balance. However, many teams and private owners modify the wheels and tires according to track conditions and personal preferences. The car’s suspension geometry and wheel arches can support wider tires for increased contact patch and better traction, provided fitment is within the aerodynamic and regulatory constraints of the GT4 class or other race series it competes in. These adjustments can improve lap times and cornering performance by enhancing grip and overall respondence.
