PitchCar Extension

 From the publisher's website:-

You’ll create a vast number of tracks with weird new pieces:
   . Challenge your sense of accuracy with the chicane.
   . Hug a bend to pass your opponents or take the outer path with double-trajectory curves.
   . Fly over the track thanks to the two springboards (provided with a bridge and a tunnel, only in the PitchCar box).

-- You need the basic game to play --

Contents: 12 rails, 4 double-trajectory curves, 1 chicane, 2 special long straights, 2 springboards, (1 bridge, 1 tunnel,) 1 booklet.
