Synchrotech's BRZ/FRS/GT86 carbon synchronizer kit for your AZ6 manual transmission was developed from the need to improve shifting feel and time of the AZ6 manual.
Through an improved friction surface, carbon, these synchros allow improved shifting at high and low RPM. These units will improve shifting feel, gear engagement, and gear longevity.
Note: Comes as a set. One set includes all 6 gears.
