Cruising in Overdrive

 The overdrive is an easy solution to increasing the top end cruising range of the Ghost.  Prior to installing the Gear Vendors overdrive, my Ghost’s sweet spot for cruising was about 50 mph, it now purrs along easily at 55-65 mph with less noise and engine vibration.    For cars fitted with original 14/52 rear axles, it’s a significant improvement in extending the top end speeds.  The mechanical noise from the engine and drive train is also much lower since the engine in not working as hard. The net result is a more pleasant ride.
