Call Fall-Line Motorsports in Northbrook, IL at 847-480-9804. They have an excellent shop near them which they use for all their alignment work--and they (Fall-Line's work) are all race car and high performance street car jobs. You can get any setup you request, and it is dead accurate.
Much closer than Oconomowoc.
Tell them Jack (Z4) sent you. And, take time to look at the cars in Fall-Line when you go--big, big budgets being spent there--Very nice for race nuts to visit. They might still be building an American Le Mans Series car if you go soon.
