Same problem here and most time I'm not even trying. Just trying to quickly accelerate pulling into traffic and my little pizza cutter tires let loose.

 

Really, I have those too but when mine was stock it slipped but never spun. Now that the engine cranks out about another 50 hp and 50 ft lbs. it's a different story. I don't even have to launch it now. If I launch now I produce smoke and I have 265 wide tires.
