You really need to check ALL your drains, not just the front ones. Water will collect toward the front, even with the rears clogged.
Please also pull your carpet look to really check what's happening. There is insulation under the carpet that soaks up water like crazy! By the time you realize that you have wet carpet, the insulation will be saturated with water. Been there, done that, luckily, not on my current Boxster.
