Harmon;
First, make sure that you are measuring your toe-in at the ride height that you will be running on the salt. Any toe scrubs the tires and absorbs a bit of horsepower, so setting it at zero is best. Toe-in is usually a compromise to allow for the deflections of the suspension under load. The tighter the rod-ends, etc, the closer to zero you can set it. It is a good idea to check your bump steer while you are at it.
