Just the one driver. The spring doesn't change the location of the pedal, it just makes it harder to push in, and it comes back up faster. I do have a Throttle Max on it as well, that extends the foot pedal.Was it just one driver or 2 drivers? I am thinking about something but it has to be comfortable for 2 different types
The best thing about the spring is when you hit bumps and your foot hits the pedal, it doesn't engage easily. That is the fix I was looking for. So it really depends on what kind of riding you and your two Gf's do!!
