    Alignment specs for my setup?

    Here is what I having installed now:
    > Lemfoerder Front Control Arms
    > Front Control Arm Bushings (urethane)
    > Rear Subframe Bushings (urethane)
    > Rear Trailing arm bushings, fixed position (urethane)
    > Diff Mount (Urethane)
    > Urethane Rear Shock Mount
    > UUC Front and Rear Swar Bar Kit
    > Vorshlag Camber/Caster Plates
    > H&R Race Springs

    The shocks are Billie Sports.

    What settings should I request from the alignment shop based on the following:
    - Car is street driven regularly
    - Car will also be going to the track and autoX

    With the camber plates, I assume a good shop can mark off a few settings, right?

    How long do you want your tires to last?

      lol... good question. I am of the impression that as far as the front goes, I can use the camber plates to make the geometry good for the street and for the track, but for the rear I'm not sure. I guess I'd have to run some kind of compromise.

      What do you think would be reasonable? I am very open to suggestion (did I just say that?).

        if you dont have any eccentric bushings or camber/caster plates in the rear then you cant adjust anything. Get your toe up front set to as close to 0 as possible maybe 1/8" of total toe. And as for the camber and caster, set the camber to center to retain stock geometry and set the caster to stock. Then have them align it. Get your readings from the alignment and ajdust where you want it. Thats what I did

          With the parts you are using, the rear suspension alignment is fixed and can't be changed. But it should be checked to see if one of the trailing arms are bent. For a car that will will be regularly driven on the street, set the front alignment to stock specs. That will yield stable handling and good tire wear. For the track you want the camber called for by the tires you run and zero to a touch (1/16" total) of toe out.

          For the cost of a camber gage, a tape measure and a home made pair of toe plates you can align the front end yourself in about an hour.

            The shop installing my suspension told me they send the car across the street for alignment when they are done, so I assume without direction from me they will make it street-style.

            Then my question is: If I mark off where the plates are when I get it, and then go to an autoX and dial up the negative camber to whatever is best, and then return to the marks I made afterwards, I should be good, right?

            Basically, I need you guys to edumucate me about camber plates.

            In the meantime, car should be back tomorrow. I cannot WAIT to try it.

              I plan on running the max. amount of negative camber that is within factory spec. on the front and just a sliver of toe-in. That way my tires wont hate me and the slight amount of toe in will keep it from getting too squirrely in a straight line.

                If you can make a good index mark for each of the positions (street & track setting) that will work reasonably well.
