the oem seat back starts heading back and then straightens a bit as it goes up. What happened with the 3" rise was that it basically put me further back, so I needed to adjust the pedals. The pedal adjustment is just a series of bolt holes that you unbolt from underneath, pick up the mounting plate and move it to the next set. I really need to just drill a set of holes about 1/2 in between as now my left leg is really cranked up when driving.
