Just a note about manual steering.
I was talking to a guy about removing the power steering on my Hybrid and they strongly advised against it, saying that if you start tank slapping at 80mph, a car with PAS will be a lot easier to control than a car without. The car without needing arms like incredible hulk to control it should it all go a bit wrong. Also with no PAS, the 'snatch' will be very violent, possibly breaking your thumbs! lol!
I'm no mechanic nor a driving guru, but just my 2p's worth.
