I have a small kei van and use it for camping/picnics. However, it is older and is parked in 1st gear/reverse gear and handbrake. It still allows for some 'rocks' to pass when getting in and out, so the placement of these two on the front wheel has been reduced, assuring me they won't roll away. Bright red to match the red van, snaps back into the box for easy storage without messing up the floor mats.
