Just stating the recirc. steering box is fine in a street car ,unless your looking to do some professional racing?I don't think the rack would add that much that you would notice it on the street.Most cars use racks because there cheaper and use less parts.MB probably uses str boxes for less noise and vibration.Some people just find it odd that you would change something that the car does extremly well.Skid pad doesn't impress me much,its what the car can do through a winding country road that gets my attention. Just my 2 cents.The one thing I would change would be the leg room.
