well guys i'd like to give an update. went to the alignment shop today and told them my situation. right before they took it into the garage bay they told me "you running on slicks!?" i laughed and said i wish....the guy says, "no i'm telling you." turns out my rear tires where completely bald
...hence why so much wobbling in the rain
purchased some new tires and everything seems to be back to normal. i don't know if its my head or not but i insist i still felt some small wobbles....gonna go back sometime this week and get my alignment inspected
