OS Giken's testing has found the FT-86 chassis to perform much faster utilizing their custom spec 1- Way differential tuning. Typically Torsen differentials do not evenly distribute applied power and never achieve 100% lock. The OS Giken Super Lock allows for precise lock timing for consistency in performance regardless of surface conditions. In a ProSolo setting, launches are important as competitors constantly seek better 60 foot times.

The OS Giken Super Lock differential will prove more predictable and easier to control the vehicle in comparison. This tune has proven amongst test vehicles to be the smoothest and easiest setting to drive fast consistently. OS Giken differentials are known for their seamless lock timing and having a quiet operation. This specific STX tune continues with that philosophy and brings reliability, comfort and performance in one package.

The OS Giken Super Lock LSD is the culmination of over four years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with their patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance.
