Are smaller cars harder to lift with the wide lift?

I need a few more pros vs cons about symmetrical vs asymmetrical. I'm still not sure which one is more appropriate when and why.

I've had a 2 post Rotary lift for years and it's the A-symetrical style. The concrete is 6" whereas the rest of my concrete is 4". The rated lift weight max is 7500lbs, so anything I own is fine. I've had suburbans on it and no issues to date. I would also suggest you buy a few rubber pads to lay onto the mounting plates. this keeps it away from metal to metal surfaces. What I've always been told is the symetrical style is typically used for very long wheelbases. What are you planning on lifting?? Also mine is run on 120vac. The arms are telescopic so lifting small vehicles are no problems.
