    ALIGNMENT specs with upgraded suspension?

    IMG_6094.jpg

    I have Eibach upgraded suspension and wonder when i get an alignment if i use the same specs as stock suspension?


    I believe these are stock:
    Toe-In: 3mm (0.12 inch) per wheel
    Caster Angle: 3.5° to 4° Positive non-adjustable
    Camber Angle: 0° to 0.5° Negative
    King Pin Inclination: 6° ± 0.5° - 0° non-adjustable

    this is taken from maintenance manual :

    That’s a great question. I have the Eibach setup too but I haven’t needed an alignment yet. Contacting DMCH directly is probably the way to go.

    The answer is yes, but. If you lowered the ride height you may not be able to achieve all of the specs. Get the specs and the procedure from the Service Bulletin ST-34-1/82 and don't forget the rear specs. You also need the torque specs and make sure the recalls have been done.

    your camber will likely be out of spec, especially in the rear.
    Without adjustable rear links you can only adjust the toe front and back, 1/8" in all around.
    Everything else is just a reference. Even if it is out there is no way to change it.

    If you are spending for an alignment you might as well get all four wheels done. Because the car is lowered you really should have adjustable rear lower links so you can properly set the rear camber. Take ST-09-7/81 for the torque specs too. You DO NOT want to overtorque the TAB's (Trailing Arm Bolts) in the rear. If the shop has a modern machine the Delorean specs should already be in it. If not they can input them as a custom spec manually. When you leave make sure the steering wheel is perfectly straight when driving straight and it turns equally in each direction (same # of turns to lock on each side). On a flat road (with no crown) the car should drive straight. Before going remove as much junk from the car as you can, check the tire pressures and have a 1/2 tank of gas. The shop is supposed to inspect the suspension and steering for any loose or worn parts BEFORE attempting an alignment. The only things easily adjustable is the toe front and rear and if you have the adjustable rear links, the rear camber. If the other specs are out it means something is bent or the car is lowered.
