Try a 30 Degree high banked corner just like the real stock cars race on. Add a 9 inch radius banked curve that comes with a set of bank supports so you can make a 4 lane banked curve. This package contains 2 pieces of standard 15 inch straight track, and 4 pieces of 1/8 circle (30 degrees) 12 inch banked curved track. When assembled it forms a complete 12 inch banked curve set. Note: the banking supports for four lane configurations come with the 9 inch radius banked curve set. Please note: this item replaces AFX #8991.
