I also have a Greg Smith --- 2 post 9000 symetrical 143" inches tall- top crossbar. Mine is 220v and mounted in 5" of concretet floor. It is also attached to the trusses in the ceiling. If you get something long , the tall screw up floor jacks -- front/back --from Greg Smith prevents teetering but also probably not needed. I believe door opening is easier on an assymetrical but I am guessing load is assymetrical also. If installed properly they must be ok as many people have them.

A wide lift will allow easier door opening also as mongo mentioned above.


Beside c5 and c6 vettes ---- arms will not reach lift points----c4 is ok, newer swbs are harder to pick up as you may have to put rear pads on the leaf spring. If I bought again, would probably get an 11K -- more overkill for my needs.
