The comprehensive kit was developed in collaboration with English author and tuner Lyndon Lewington of ARC Tuning and Jonas Fehlhaber, two-time world champion in the HFT Springer. It was based on Steve Pope's well-known and proven V-Mach tuning kit. All components are meticulously individually matched using a V-Mach piston spring made of Japanese valve spring steel. The spring and system are decoupled by Teflon Jonas washers to absorb and balance the rotational forces of the spring.
