Tires (and maybe alignment) should fix it. My ap2 is absolutely planted in the rain. S04 tires in good shape, lowered slightly on stock shocks. Stock alignment specs.
yeah I plan on getting an alignment once I put my coils and wheels on

Just curious... what was the outside temp, and are you summer tires? If it's frigid, summer tires behave terribly.

zero toe and planted, but still don't like driving in the rain. lol
static zero toe is likely toe out when driving, this sounds like a bad idea for our cars

zero toe front and a small amount of rear toe in is an alignment on the slightly more aggressive side

As you approach 40 degrees, summer performances tires degrade quite a bit, according to Michelin, Car and Track and others sources. In addition, when rain first begins after a dry period, oils and other contaminents come to the surface making things slippery.

Changing surfaces, as others have pointed out, can suddenly affect traction. I recall a number of accident threads when an S driver hit the steel mesh on a bridge and lost control.

55 deg. should have been OK. If it was 40 or lower (as Cosmomiller mentioned) I would suspect that being part of it, but summer tires should be fine at 55.

I've had the same issues since I put my coilovers on and my toe came out of wack. Check your alignment.

Alignment and/or tires.
I've driven through massive rainfall and standing water in mine and it's remained planted and confidently footed. I've got new PSS tires and recent US spec alignment.

Sometime the highways are really damaged because of heavy truck traffic and you are essentially driving in a couple of ruts.

That's a hard no. Unless you have a rear bumpsteer kit AND that kit has been properly tuned and measured through the suspension range of travel AND you have zero deflection spherical bushings at every suspension connection point, then running "zero toe" in the rear is going to make the car loose and unpredictable, especially when braking, because the bumpsteer and suspension deflection cause toe out as the rear unloads.

The stock alignment is slight toe-in in the rear and zero in the front and that works pretty well for most folks unless they have the above heavy modifications to support less rear toe.
