CRG and Maxter are two winning brands that have always been present in karting. CRG is the evolution of an historic brand, Calogero Vanaria’s KalìKart. Calogero’s sons, Carlo and Roberto Vanaria started this adventure in 1987 with Giancarlo Tinini after taking over KalìKart. Then, with the new millennium, the trio broke up and Giancarlo Tinini took all the responsibility of going ahead and widening his range of production into three completely different lines: CRG, Maranello and Zanardi; well-known international brands for some years now. However, Giancarlo Tinini, who loves his job, after the new, winning production of kart fairings mounted on several brands of chassis, continues in his innovative policy, without loosing the prerogative of care in details.
CRG is one of the most representative teams for Formula 1: Hamilton, present world leader, Liuzzi, Kubica and Rosberg, all protagonists of top level of motor racing, have all raced and won in karting with CRG only; a fact, a primacy, not to underestimate. Also Maxter is in the development project of the factory based in Brescia. They are working in KF, in the three TaG classes and in KZ, the gear class 125cc. Three world titles gained from 2001 to 2003. But in 2007, they have met some difficulties with new homologation.
New chassis homologations will be in January 2009, but development of systems and accessories is in continuous evolution. For example, the latest innovation is a new lighter braking system whose disk is made of a special material, Duralcan, whose base is aluminium. The surface has been treated and coated with a type of ceramic material. The disk, floating and auto-ventilated, allows a cut in weight compared to the cast iron auto-ventilated system, both for overall mass and for the rotating masses. Both aspects allow for improved acceleration and maintain excellent braking characteristics. This advantage is more noticeable in the KF classes where propellers are limited and hence the effects of inertia drop in accelerating. Thanks to reduced weight of rotating masses it’s now even more sensitive. CRG had already made lighter auto-ventilated steel braking systems. Today though, with bigger radiators that cover rear disk and better performing propellers it has become necessary to mount auto-ventilated, especially on twisting circuits where you have to use brake and acceleration continuously. Pads, green, are made of a material containing more ferrite and less organic components, which works at higher temperatures compared to the traditional ones, and therefore, they adapt more to the Duralcan disks. CRG chassis offer you the opportunity to mount either the traditional self-ventilated cast iron braking systems or the new lighter system that adapts better to the average weight for drivers. Braking systems, however, apart from CRG, are being made for some years now for other factories too...
