sharp full wheel turn

For the feeling of lack of grip, this is also normal as that side of the car/tire is under static camber during compression. There will be less of a contact patch on the outside edge of the tire (or inside edge depending on which wheel you're talking about). You actually get more grip, unless your alignment is out of spec. It just feels like less grip because of the quicker turn in from the front wheels whilst the rears aren't moving as much.
