Close to getting "Bitten" by the GT3...anyone else?

At least a few times that I could recall. Had my .2 GT3 manual for a few weeks now, still in the break-in period.
I have noticed a few times under moderate acceleration (despite dry pavement/tires warmed/pressures checked), the rear tends to slip/snap loose.
Caught me by surprise a few times, a bit scary feeling. I guess this car deserves some extra attention and respect. Not sure if owners experienced similar events?
Thanks,
Jack

What was the temp outside? GT3.2 does have a lot of power and torque (despite what most people say) but it’s also one of the best RWD cars to put the power to the ground...prob a combo of cold temps cold tires and uneven road etc

If it's really sunny, you might have high enough surface temp at 48F ambient - but in most cases you need >55F...

This is your issue. I assumed the temperature was warmer than this, since you're in CA. The Cup tires don't work well under 55F. You cannot put enough heat into them on the street in that weather. At a track, you might be able to get them to proper temp after a few laps, but not at any sane street pace.

Sure - sorry that it may not be the answer you wanted. GT3's come on what are basically racing tires (even more extreme than what are generally known as Summer tires). For use in cool/cold temps on the street, the Cup tires basically behave like you're driving in the wet (or other reduced friction situations). For those of us who are used to driving old 911's in low friction conditions, it's no big deal (but still requires full attention and reduced pace). For someone who may not be expecting greatly reduced grip, it can be quite eye-opening (or even dangerous). Unfortunately, Porsche has not made it easy for someone to fit Winter or even All-Season tires for use in colder conditions. To do it properly, it really requires a second set of wheels (11" rear width, optimally).
Your grip may improve noticeably, once you're worn away the mold release that was mentioned earlier in the thread. But they are never going to behave at 48F like they do in the warm weather.
