[JUS BIT]

Ray, I attached mine with #10 stainless button head bolts in 6 places. I can remove or attach it in about 20 minutes at the most. I have run mine on the street, but like the others said, you have you have to be careful not to bottom out. If you have a good transition on the driveway, then it should work.

Also, I have a rubber seal between the body and the spoiler to keep it from scratching the paint.

Bests, James
