What Sharp said.

Although it is possible to get decent wet-weather behavior as long as the temperatures don't drop too low.

I can tell you that Goodyear Asymmetrics (a max summer performance tire) get pretty dodgy at temperatures under about 45°F with only a 4.6L normally aspirated engine working them.


Could be that the initial tip-in response is just too much. Perhaps some enterprising ECU tuner can come up with a tune that initially opens the throttle less aggressively than OE. This is something that at least one top-level Mustang autocrosser ended up doing to make that car behave a little nicer at the (dry) limit between the cones, and I've done something analogous on a mechanical throttle to slow down the opening of an oversize throttle body (also for autocross, where fine throttle modulation is a really good thing - and relevant to what you're looking for).

You might even consider installing a softer rear sta-bar or a slightly stiffer front bar for the colder months, just to leave a little more rear tire grip available to resist power-induced wheelspin.
