Designed for the factory Scion FR-S / 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 ratio1st and 2nd gear which prevents engine revolution drop during up-shifting to keep the RPMs in the optimal range. Combined with a lower ratio 4.566 nal gear, this is the most powerful modification that can be done to extract the full potential of the naturally aspirated machine.
