That one appears not to be an extender, it changes the angle/profile of the pedal & arm to increase throttle response. I'm looking for pedal extender so the gas pedal will be closer to the floor for my wife whose small frame & feet make it almost impossible for her to keep steady contact with the gas pedal. She has to hover or wedge her foot to keep it pressed. Not ideal and gives her very poor control which can be dangerous in technical or hilly terrain.
I saw their's. It might be an option, didn't want to go with a slider cover like that though. I would think it might still be harder for her to press since it is hinged on the bottom but still having to push the original pedal lever back to so two points making it more difficult???? But on his video, it seems fine and his video says he raced with it. That might be an option if there are no other vendor's with an actual extended pedal.Desert molding concept's has one
