Welcome! Nice looking car.
I just did a partial suspension refresh on my '02 S, which included two new track rod ends, one rear lower control arm, new Bilsteins and all accompanying strut hardware. It made a BIG difference. Definitely stiff enough for me given a majority of what I will do is street driving; however if you plan on seriously tracking your car I'd consider PSS10's (and a deeper, baffled oil sump).
I'm in Seattle proper. Wave if you see me (I'm driving it on the non-rainy days this week...)
