718 Autocross starting setup for A Street

I got a 718 Cayman base that I plan to run in SCCA A Street next year.

This is my first Porsche (I'm coming from a BMW M4), so I'm looking for a starting point on setup.

I have PDK, Sport Chrono, PASM and PTV.

My wheels are 19 x 8.5 ET50 front and 19 x 10.5 ET40 rears.

For tires, I was able to move lightly used (two events) RE71Rs from the M4. They are 265/35R19 in front and 285/35R19 in back.

So what are good starting points for:

1) tire pressures
2) alignment
3) anti-roll bars

Thanks!

John

I personally didn't change out either of the sway bars and felt the car was just about perfect. If you move to 305 rear tires, you may want to add an adjustable rear bar.
