Gold Kart is a historical brand in the world of karting. For several years, it has been owned by the Righetti Ridolfi company, which has made it the most prominent brand for racing. The GTR30 chassis is one of the top products in which many investments have been made, in terms of research and development to bring it to the top of quality and performance, this is clearly visible. Originally presented in 2012, its homologation was renewed in 2018 and is valid until 2021 (it was in 2020 before the Federation postponed it, for everyone, by one year). The work implemented on the 2020 version of the GT30 has focused on accessories and design.
The 2020 version of the GTR 30 is unchanged compared to the previous version both in the geometry of the tubes (30 mm in diameter) and in the main features. The welding method used by Righetti Ridolfi remains unchanged as well: executed manually and entrusted to highly specialized personnel. There is, however no lack of innovations, starting from the material of the tubes, one of the key factors to optimize the performance of the chassis: the technicians at Righetti Ridolfi have tested different types of tubes hardness and defined the best one for the chassis according to the type of tires used.
The fairing kit, particularly the front spoiler and the number-bearing front fairing which, on the GTR 30 are the Eurostar Dynamica model, is certainly a more striking innovation. The fairings, tested in a wind tunnel, have shown a reduction in aerodynamic resistance (the “Drag”), improving the penetration of the kart and driver while optimizing the air flow.
