Smokem Racing’s new RS chassis plate for the ARC R12 offers reduced scrub compared to the factory chassis. By removing the short arm suspension mounts, the RS design eliminates excess material from the profile that’s no longer required. The new RS chassis also moves the holes for the rear suspension blocks forward by 1mm which allows racers who use ARC’s R12 ATS system with parallel hinge pins to maintain the same wheelbase by using no shims in front of the suspension arms, something that cannot be achieved with the factory chassis without modifying the suspension arms. Meanwhile racers who run the fixed rear toe suspension can maintain their stock wheelbase by using 2mm of shims in front of the suspension arms instead of 1mm. The chassis is made from high quality 2.25mm thick carbon fibre.
