Automated welds with meticulous attention to detail; accessories CNC machined from solid; sought after materials; inventive technical solutions ... The Parolin Racing Le Mans chassis is packed with "ingredients" that are worth analysing in detail
Parolin Racing Kart is a manufacturer that has been present in karting for over 30 years. Steadfastly managed by its founder, Albino Parolin, it has invested heavily in automated welding, with state-of-the-art robot machinery that produce a uniform welding cord on every frame and uniform quality on all chassis.
The Le Mans chassis is one of the company's top models, approved in 2015 and with updates to several details (within the parameters of its approval, naturally) in subsequent years. TKART has analysed it in its KZ version, although the chassis is suitable for all engines.
The Le Mans chassis tubes are mostly 30 mm in diameter, with only the front tube connecting the right and left longerons having a diameter of 32 mm.
This tube plays an important role in adapting the frame to the different types of tyres used in the various championships and classes, thanks to Parolin engineers having a choice of 10/12 tubes with different levels of hardness, depending on the mix of tyres with which it will be used.
The chassis has a traditional design. Parolin explains: "The geometries of the Le Mans frame are unchanged over the years, but have been tweaked and improved continuously. The real difference is the material, an area in which research and development has made significant strides".
“In the field of racing, we have also developed a thermal treatment: a process that extends the lifespan of frames, eliminating post-welding stresses; it also makes it possible to increase or decrease certain characteristics of the material”. Regarding the accessories, the distinguishing feature is the steering column support. This boxed element has an internal slide allowing the steering column to move forwards or backwards, making it easier to change the parameters of the Ackerman angle and, therefore, adjust the chassis to the track and the driver’s preferences.
