[200q20v] Oversteer in stock 91 200tq

Do many people have experience with this?  Seems like everything I read about the factory tuning shows peoples experience to be of a car heavily biased towards understeer.  Although I've got to wonder if it has anything to do with my tire setup (different types of the same size Toyo tires on the front verse the rear), I have noticed a tendency for some power-on, lift-throttle, and late-braking (or is it trail-braking) oversteer in the wet.  To be fair though, of the above, I have only seen late braking oversteer carry on into dry conditions.  It is kind of fun in certain situations (slower, sharper, 2nd-gearish speed corners in the wet) but in wet conditions on higher speed sweepers (ie freeway exchanges), there is a noticable twitchiness in the rear of the car relative to throttle.  All else aside, the higher speed corners are somewhat humbling, and well my driving style is stymied in these conditions; I'm not to thrilled about the prospects of cracking my car up.  Have had the chance to experiment in quasi-track conditions (office park at about 1 in the morning on a Saturday night), but never on a true track with better runout conditions.  What are others experience with this?  Any advice?  

As an aside, in my office park experience I did find that the right amount of throttle in my one and only 3rd gear corner did help to keep the rear planted, but...
