My garage door is 7 ft tall, but the problem is that the floor in the garage angles up, so the lowest clearance point is only 6' 4 is too short for an SUV. We have 20 inches of head room above the door height to the ceiling. Not sure if I can just purchase a curve track that has about an 80 inch turn radius vs. the current 90 degree. This would give me the height I need. Any thoughts?
