    -04 STI with 300WHP
    -Front/rear sway bars installed
    -225/45/r17 Falken tires

    -Just had BC Inverted coilovers installed and was curious, after reading the thousand threads on these shocks, what a good number for camber and Caster would be??

    Toe: leave at 0 all around
    Camber: ??
    Caster??

    For what use?

    In general, as much negative camber as you can get up front and slightly less in back (i.e. -3f, -2.25r)
    Caster, as much as you can get. Not sure if you can angle the top hats that came with your BC's, but if you can angle them inwards ( / \ ) so you can max them out and get positive caster and negative camber from them.

    I like a little toe out in front in these cars.

    if you're not actually out playing in some form of motorsport, i'd say fronts between -2 to -2.5.. if you're going to autox/track, take that up to -3 to -3.5 (front camber), rear i generally run mine closer to -1.2 to get the ****er to rotate in the tight stuff.. again, not going for cutting edge i'd say closer to -1.5 to -1.8. personally i think -2.25 would just exacerbate the understeer issues these cars have.

    If you've got camber plates, i'm with idget, and suggest switching sides. this puts the plate at about a 45* angle to the chassis, and will allow you considerably more caster. without doing that, caster is not adjustable.

    Toe, i'd say zero all around, with a bias towards toe out, actually getting perfectly zero is nearly impossible, so when you have to settle close, settle on toe out. A little in the front wouldn't be bad, but I'd recommend against any considerable toe out in the rear until you've driven the car more. these things get mighty lift off rotation happy when you crank the rates up and then start to toe out. alot of people wont handle that reaction well.

    Agreed, Shane. I'm saying -2.25 rear bc that's more realistic given the hardware that people typically use. With any amount of lowering and bolts, that's about the least you can run. With rear camber plates, adjustable lateral links, higher ride height, etc... you can get it down to where you're suggesting.

    Kova, what's your suspension hardware list look like (in terms of adjustability).
