IPK research and development: the 2021 technical innovations of the RS Kart chassis
Safety and performance are two key aspects that guided the efforts of IPKarting as it worked to improve the RS Kart chassis for the 2021 season. The IPKarting technicians studied and produced a variety of innovations with regards to the components of the RS karts, designing them at the factory and then testing them at the track in order to upgrade the chassis’ performance, facilitate its use and increase its safety in all classes, from MINI to KZ.
NEW ADJUSTABLE LOWER SEAT SUPPORT
With the aim of easing the seat’s assembly and adjustment on the chassis as well as of fine-tuning the chassis’ own reliability, IPK realised the new lower seat support. A double-hole bushing is welded to the frame of the 2021 RS karts and an L-shaped plate is fastened on it. The plate is characterised by one slotted hole and therefore it can freely tilt to the right or to the left according to the seat’s position. The new fastening system provides a significant advantage compared to the previous one, as the seat support doesn’t have to be repeatedly bent and this eliminates the issue of possible breakages.
NEW EXTRA SHORT MINI HUB WITH A 30 MM INTERNAL DIAMETER AND 25 MM WIDTH
Thinking about the youngest drivers, a new aluminium hub enriched the 2021 range of accessories for the RS MINI kart, the Monster EVO 3. Respecting IPK’s tradition, the rear hub is machined from a solid piece of metal, and with a 25 mm width it represents the shortest size available. Adapting the setup to higher grip conditions is the goal of this innovation and, as a matter of fact, it increases the smoothness of the chassis.
NEW BUSHING FOR THE 0.5° CCS SYSTEM
In order to achieve a wider range of opportunities for adjusting the CCS system (Camber Caster Regulation System), the IPKarting technicians also developed a new bushing. This solution enables to refine the Camber and Caster with 0.5-degree variations. Consequently, considering the 1-degree and 2-degree bushings too, customers have the greatest chance of making the go-kart’s setup the most suitable to any track condition.
NEW BRAKE DISC
IPK’s 2021 innovations also acted upon their homemade brake system, which is installed on RS Kart chassis and sees safety at the top of the requirements list. The Research and Development department focused on improving the reliability of its bake discs and, after detailed analyses, defined a new material, which doubles the tensile strength as well as the yield point in comparison to the previous version, but maintains an unaltered braking performance. Additionally, the 149 mm, 187 mm and 195 mm discs increased their thickness by 0.5 mm, with this feature extending the component’s life cycle. A further benefit of the new brake discs regards the use of the pad cleaning groove, which can be now considered an indicator of the disc’s wear in order to avoid breakage. In fact, the disc must be replaced if the 0.5 mm deep grooves on its surface aren’t visible along their entire length. Lastly, the new discs are perfectly compatible with the braking systems of the IPKarting range.
