Alignment help
Just finished some suspension changes on my ap1.
moddiction front sway bar
ap2 read sway bar
front bumpsteer kit
bc br coilovers with swift springs. I believe the springs to be 10kf front and rear
17x9 rim with 245s all the way around.
This is a weekend car with occasional autocross, more backroads then anything.
I can have a buddy setup whatever I want at wheels works. So before I head over I wanted an idea of what would benefit me. Thanks

Are you concerned about fender clearance?
0 toe front; 1/8 toe in per side in the rear
5.5-6 degrees of caster, no more since it's a street car
And depending on your tire brand and model I would run 1-1.5 degrees of (negative) camber all the way around

Take a look at the STR autocross alignment thread might give you some ideas. I've got a stock suspension '00 AP1 with 255 square tires.
Alignment is as follows: Camber F/R -2/-3, 0 front toe, 0.2 degrees total toe in. That comes out to about 0.09 inches total toe in. I left caster alone
I kind of went really extreme with the rear camber because I was anticipating the car being really squirly due to the square tire setup shifting the grip balance far to the front. However I was wrong. On first impression I thought the car was really planted in street driving. Going to 255 in the rear from OEM 225 has stabilized the car a lot and 255 in the front provides a ton of turn in. I can feel some trailing over steer on lift off but it's predictable and allows me to easily control the attitude of the car mid corner through throttle. I've got some on-power push right now so I'll probably be dialing in more front camber or dialing out some rear, or both. It's not bad and I usually can correct it with more steering angle. You'll likely need less camber bias front to rear given you've got square spring rates and a bigger front/ softer rear bar.
The car still feels quite planted during autocross as well, however I can understand why most go for a bigger front sway bar as the front feels slightly lazy during transitions in slaloms. Rear end feels lively but I wouldn't call it nervous, likely due to big rear tires. Compared to my buddy's '01 B street car which has 225 square and big front bar I'd say his car turns in much better because of the sway bar but is more twitchy in the rear, likely due to narrower rear tires. It's quite hard for me to shake the rear end loose at all with my car, however I'm far from a quick driver. I know I've got a lot less toe in than most people but I went with it from a friend's recommendation and IMO the rear end still feels appropriately stable when pushing it in autocross. I might dial in some more toe in the future.

Camber front -2
Toe front 0
Camber rear -2 (if you dont need more to clear wheels)
Rear toe .20 deg on each side (recommend getting a rear bump steer kit)
