Ride Height and Ground Clearance.

My drive way is on a hill, did front end during rainy/ summer season, still haven't finalized ride height. There is NO equal place in drive.
higher in front, slanted all the way across. I even have a self leveling laser... I just want a flat slab, dammit! Lol
I guess Ill be doing my ride height in the barn, probably when it's 25 degrees out. it has a thick level wood floor. In the cold *** barn Cuz every other garage space is either small or full of stuff.
