Ferrari 365 GTS/4 Daytona Spyder Parts & Accessories

The Ferrari 365 GTS/4 is the open-top spyder version of the Daytona, produced in only 122 examples between 1969 and 1973 compared to the 1,283 closed berlinetta 365 GTB/4 coupes, making it one of the most significant and valuable of all classic Ferraris. The GTS/4 shares the quad-cam 4.4-liter V12 and the overall chassis engineering of the closed Daytona while replacing the fixed berlinetta roof with a soft top mechanism and a revised rear deck that dramatically changes the car's visual character. Sourcing parts for the 365 GTS/4 requires the same detailed knowledge as working on the Daytona berlinetta, with the additional complexity of the open-top body's specific components, soft top hardware, and convertible body reinforcements that are unique to the spyder form. The extraordinary market value of the 365 GTS/4 means that any part sourced for one must be correctly specified, and the authentication standards that apply to the car's overall provenance extend to significant replacement components.

Popular Upgrades

Weber 40 DCN carburetor rebuild kits, quad-cam timing components, and valve cover gaskets for the twin-cam V12 heads are the same foundational engine service items as on the 365 GTB/4 berlinetta. Soft top fabric and frame hardware, header bow latching components, and convertible-specific weather seals are the primary open-top body service items specific to the GTS/4. Front and rear suspension bushings, Koni shock absorbers, and wheel bearings support chassis refreshes that maintain the handling quality appropriate for this car's performance capability. Brake hardware including caliper seals, master cylinder rebuild kits, and Ferodo DS11 or equivalent friction pads are critical service items for a car with this power output and value.

Performance and Handling

The 365 GTS/4 shares the Daytona berlinetta's fundamental performance capability, with the 352-horsepower quad-cam V12 providing the same top speed potential in a body that adds modest weight through convertible reinforcement and soft top hardware. Open-air driving at sustained high speed in a 365 GTS/4 is one of the most remarkable automotive experiences available, with the V12's induction and exhaust note completely unfiltered by roof structure and windows at full throttle. The suspension geometry and handling character of the GTS/4 mirror the berlinetta's, providing the same balanced, high-speed stability that made the Daytona extraordinary in period. Maintaining correct geometry settings and fresh suspension components preserves the handling precision that defines this car at the performance level it was designed to operate at.

What makes the Ferrari 365 GTS/4 so valuable compared to the berlinetta?

The 365 GTS/4's production number of 122 examples versus 1,283 berlinettas creates a supply-demand imbalance that has consistently pushed spyder values to multiples of berlinetta prices in the collector market. Open-top Daytona motoring is fundamentally different from the closed car experience, and the rarity of authentic spyders combined with the impossibility of creating new ones means that collector demand consistently outpaces supply. The additional consideration that many of the world's 365 GTS/4 examples are in known collections and rarely change hands further restricts available supply and supports the extraordinary valuation the model commands.

How should I authenticate replacement body components for a 365 GTS/4?

Authentication of body components for a car of this value requires tracing parts through documented sources including established Ferrari marque specialists, auction house provenance records, and where applicable the Ferrari Classiche authentication program that Ferrari's official restoration service provides. Significant body panels, engine components, and convertible-specific hardware sourced for a 365 GTS/4 should be documented carefully to maintain the car's complete provenance chain. Working with restoration specialists who have documented experience with 365 GTS/4 cars provides both authentication assurance and access to parts networks that serve this specific model.
