Can be used with S15 transmissions as well.
By hardening the inner rubber of a standard shift lever, the amount of deflection is decreased. At the same time, the lever length is reduced by about 7.5mm, providing a stroke 10% shorter. This changes the rather soft touch of the standard shifter to a much more precise, fast feeling. At the same time, while the goal is to change to a quicker shift, an overly short shift stroke will result in poor, heavy shifting. The lever ratio has not been changed on this unit, so the transmission synchros is not affected and a moderately faster degree of shifting is possible. Installation is easy with snap-ring pliers and basic hand tools.
