The 4th Dimension design was bought along with the rest of Arrow Dynamics by S&S Worldwide. S&S proceeded to built two more 4th Dimension coasters; one in Japan, Eejanaika, and the other in China, 4D Roller Coaster.
The rotation of the cars is achieved by having four rails on the track: two of these are running rails while the other two are for spin control. The two rails that control the spin of the seats move up and down relative to the track and spin the seats using a rack and pinion gear mechanism.
The trains on a Bolliger & Mabillard wing coaster are similar to a 4th Dimension train. Both models seat their riders at either side of the track, but a Wing Coaster car is fixed to track, unlike the 4th Dimension car, wich can spin under control.
