I spoke to my friend in Virginia (David) who is helping me with the set up of the car..he said I will need a perfectly flat piece of floor to put any set ups in the car....at a race shop this would be done on a surface plate (mega$$) but he told me how to make one that will work for a guy like me....so thats what I did.
I bought a cheap laser level and leveled out a spot on my shop floor.....the left front (LF) was the highest spot so it needed nothing, the RF needed 3/8" and the two rears needed a full inch to be level.....I covered the plywood with a waterproofing stain I had lying around so it would be less likely to warp or swell if it got wet.
