The development in all details makes
the hard covers to be more efficiency in aerodynamics. Air stream pass through truck and tonneau cover very splendid. The test from Bira International Circuit (Pattaya) proofs that it can save up to 15%.
We design Sport-lid as Aerodynamics method to decrease friction forces. Tonneau cover is design to be a streamline figure which helps decreasing coefficient of friction up to 14% After more over 1,000 hours of test session of design appearance that helps about rain flowing to the side tonneau cover so perfectly in the wind tunnel by the Faculty of Engineering, King Mongkut’s Institute of Technology Ladkrabang. We are devoted in all details to increase streamline and potential in driving
