I made mine adustable so that I could move them around if I raise or lower the car. It also has some effect on anti squat but I havn't tested anything yet. you can see that I made mine from Speedway products tie rods and qa1 endlinks so I can also adjust the kingpin angle on the rear (if it really matters). Mine are also longer than stock. I do have minitubs installed, with out those you would be inside the inner fender. If it helps you I have the .dxf files for most of the components that I had my buddy waterjet for me. That should be worth at least a case of beer to you!
