Why don't new Nissan Pathfinders and Frontiers come with eccentric bolts and washers?

The Nissan dealership says they don't come with eccentric bolts and washers, which according to them is necessary for proper alignment.|||because the vehicle is set to factory specification as the vehicle breaks in your vehicle tends to need adjustments and one of the ways is to align your tires.and to that, they sell kits to allows certain range of adjustments.and to have it properly aligned they are a must to hold your tires to proper specification they hold your tire in or out. which is the camber adjustment of the tire.if the top of your tire leans out you have to much camber if leans in you have to much negetive camber. to much of either will cause tire wear.|||that is correct i have worked in the tire field for 27 yrs and i can tell you not one car or truck comes with them it always is an add on after you take it to a shop or the dealer.
