Possible causes for hydroplaning/bad wet traction:

- Irregular tire wear, resulting in bald contact patches
- Unmatched tires front/rear
- Bad alignment, specifically rear toe (causing bump steer which is much more pronounced in the wet)
- Driving too fast.

Based on the description in the first post, I'm willing to bet the rear toe is way off and the vehicle was never aligned after the pro kit install, causing the tail to waggle around excessively.

It's not a problem in the dry, as both tires are usually in traction, therefore negating the toe-in. In the wet, the traction between tires can shift dramatically, resulting in this kind of behavior.

Get an alignment.
