Well, thats not really the main reason to ditch the PS, I can live with it up top if necessary.
After reading all this, I think I will be keeping it. Parasitic drag is an issue with a car like this, but the car still has to have AC. Its just too hot, and if it doesnt have it the car will not get driven near as often.
As far as the PS, I would think the lack of it would just plain get old.
