It makes daily driving less pleasant, and will reduce the value of your car when you decide to sell it. A power steering pump and lines doesn't take up too much space anyway.
I have a flaming river kit on one of my fox body stangs. Honestly once the car is rolling you can't tell the difference between that and power steering IMO. Parking is a pain in the ass if you got wide tires on the front was my only complaint. Mine is almost strictly a drag car so not like that is much of an issue for me.
My entire front suspension for my notch, including k-member, a-arms, spindles/hubs, steering rack, steering shaft, tie rod ends, struts, coil overs w/ springs, and endlinks weighs only 126 pounds. That is a HUGE difference from stock.
Yeah i agree on this one, for a DD i wouldnt recommend it, i drove a ford festiva for carquest delivering parts with no PS and it was a total WHORE parking that damn thing 35 times a day, my forearms got big though lol
