Buzz, Come on, you are an experienced person in the way of the world; There are trade offs. You want great tire mileage, buy a family sedan and put all season touring tires on it. If you want a sports car to drive and act like a sports car, put sticky summer tires on it. They are trade offs. You just can't have everything. You want higher mileage from tires you need to get harder rubber in the way of high mileage all season. The car is what it is. My last set of tires lasted just a little over 4,000 miles, but I drive it like a sports car.

Bad toe settings will wear tires out faster than camber, it will also cause the car to not track correctly. How fast the tires wear depends on how far out the toe is and your statement about the guys set all the tires to the one you can't adjust doesn't make a lot of sense. CUT THE BOLT HEAD OFF AND SIMPLE GET ANOTHER BOLT. They can be had at any place that sells metric bolts. Just for your info I run no toe on the front tires. They point straight ahead and rear toe is like 0.1 to 0.2 degrees toed in.
