For the term sweeper, I don't know what the real definition is, but I call a sweeper somewhat long/lengthy turn--basically any turn where a RWD can power slide through it with no problem.

The previous event was a replica of the national course. There were a lot of turns that are RWD friendly, and FWD friendly. The latest course (Dec.), was basically for a RWD car in this manor--Go, power slide through this 180, a slalom, power slide through this 180, set up for the next turn, powerslide through that one, haul ass down the straight away, slow down, powerslide through the last corner.
