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.
