Re: Steep garage entry
Putting carpet down would reduce the scratching.
other than that you need to somehow reduce the angle.
If you have space and can go diagonally that might help.
I have a plastic strip on the bottom of my front bumper (comes as standard on the car) and have had the same problem but because of the plastic strip I don't worry about it, just go slowly and grind the ramp on the way in/out.
