I live in New Hampshire and have no problems with internals or anything else. Anytime I punch it, I get sideways. saves internals. The car also drifts really great in the snow on exit or on-ramps with Blizzaks. May have to do with 18in wheels. May need to get 19in to put the hp to the road. Does make me smile, a lot.
