The gas pedal
These Toyota DBW pedal are horrible and when in a light car, even worse. To make it driveable under 30% throttle, I had to extend the arm more then I had to stiffen it to make it feel normal like our other cars. The shocks have thick RC silicone oil and add some resistance and slow the input like a cable. I have an adjustable oil damper to slow the closing on decel when I lift the throttle. It engages at 35%. It was the only way to be smooth going from the quick lift of gas to brake in autocross without the back wanting to come around.
