Looks promising! Some suggestions for you to try: - Try setting up the input as described here: http://evp.vehiclephysics.com/faq/#how-to-configure-the-input-parameters That would give the kart more "agility". - Move the "Handling Bias" slider slightly towards "Oversteer". Real karts tend to oversteer in dry surfaces. - Adjust the "Steerning Limit" setting so the car's steer angle is smaller with the speed. - Reduce the damper in the wheels to increase the response to bumps. At the same time, ensure to adjust suspension length and spring so the suspension doesn't compress to the maximum. Keep the good work!
