If you really want to do it right, insist on having the weight of the driver in the driver's seat (or sit in the vehicle during adjustment) and other significant weights added (such as proper fuel level and if you routinely carry cargo or passengers, have those at the proper spots). This compresses the suspension to perfect the numbers even more.
In the past, I had a shop perform an autocross-specific and the vehicle was really twitchy on the highway (thanks to Old Mech for the reminder) -- be forewarned that the 0 front toe will have the same effect. Since most of us here are pretty attentive drivers, it isn't critical, just pay extra attention. I pulled the power steering belt, so for me, twitchy is an understatement
, but FE gains are worth it...
I seem to always have front tire wear on the inside, so there's a toe-out issue (perhaps required specs for the vehicle model). The plan is to go for zero.
By the way, how does camber factor into the equation? Some of us corner aggressively to maintain momentum, but the majority of time, EcoDrivers are moving in a relatively straight line...
It would be interesting if people could post their alignment "Printout Sheets" if the shop can provide you one -- and if you notice a difference or can log better FE...
