Designed for the factory Toyota 86/Subaru BRZ 6 speed manual transmission, the close ratio gear set is ideal for keeping the power and torque band at its most effective region. The kit consists of a close ratio 1st and 2nd gear which prevents engine revolution drop during up-shifting to keep the RPMs in the optimal range.

Combined with a power ratio 4.566 final gear, this is the most powerful modification that can be done to extract the full potential of the naturally aspirated machine.
