    Just in case anyone is actually looking at this thread anymore...

    From a quick peek under the car it looks like:

    a) The stock ball joint is quite small (the screw-in Mopar balljoints are much fatter)
    b) Anything larger, or with a longer stud, will be fighting for space with the disc rotor.

    I haven't looked closely enough to determine whether a shallower rotor (e.g. VW Corrado - I've got a bunch of Miata wheels so I'm stuck with four-bolt for, well, forever even if the car does get a BEAMS) or a rotor with a much bigger 'eye' (e.g. redrilled C4 Corvette) might help with clearance. Of course neither of those options will help with stock brakes.

    It's gonna be a couple weeks before the Celica gets on the lift, I should be able to get some real measurements at that point.

    Roll Center

    What about knocking out the ball joint bolts and putting longer ones and then making like a spacer???
    because my control arms bend up like a slight V ??? could this be why I have caster Prob.

    If you're referring to the three bolts that hold the ball joints to the control arm, you're not really changing anything that matters by doing that.

    The actual 'control arm' is a straight line between the inner pivot bolt and the center of the ball-socket on the ball joint. The shape of the arm between those two points doesn't matter. All spacers will do is change the shape of the arm, not move the pivot points.

    At some point in the next few weeks I'm going to order one of these to play with:
