The most famous turn at Laguna Seca and the west coast. Most any track-rat around the world has heard of this particular turn.
The approach to the corkscrew, starts with the heavily banked turn 6, onto the uphill "Rahal Straight" then the little kink of turn 7. As you pop up the blind crest, heavy braking, a quick left (turn 8) then right for turn 8a and a 5+ story plunge down the corkscrew. The initial drop the car goes light, then as you come down the suspension compresses heavily, giving lots of grip to go deep onto the throttle. Track out to the left, gather the car up to move to track right for the downhill "Rainey Curve". Then back around and do it again. Turns 6-10 is my favorite part of this track.
