HB Racing have introduced two new sets of anti-roll bars for the D817V2, D817T, RGT8 and RGT8-E. They give racers a finer range of stiffness to help tune the car to track conditions. The front sway-bar set has 2.3mm and 2.5mm bars, and the rear sway-bar set has 2.5mm and 2.7mm bars, each
labeled with a tag that shows the stiffness.
