Stock specs

 

Front and rear OEM specifications below. You may need adjustable FUCAs.

 

Your mechanic asked for specs?

Find a new alignment shop that uses more than a string, plumb bob and ruler.

Kidding aside, any shop with computerized alignment can set your toe based on stock specs (as mentioned above) stored in the alignment machine.Toe is the the only part of the alignment triad CCT - camber, caster, toe) that's adjustable without adjustable FUCA and camber arms in the rear.(Also mentioned above.)
