i put a piece of 2x4 under the bellhousing and as far as this lift is concerned there are no balance issues at all..it goes up and down like butter. it's hard to see exactly where the engine sits on the lift because i put a towel down which was really there to protect the lift in case i had to return it. the towel seemed like it made things a bit less solid but it wasn't going anywhere and gave the engine a nice cushion. i don't think i need the towel next time but it surely didn't hurt anything.
