These replacement synchros have been designed from brass with carbon sleeves to improve shifting and durability of your stock Toyota transmission (C60, C64, C66). S111 partnered with Synchrotech who developed these from carbon-carbon tech derived from aerospace applications. Used successfully in Honda street and race cars for years. Track tested in S111’s Elise (ArtCar v2).

Extended durability and faster shifts. To enhance the OEM Toyota C-series transmission to withstand track conditions and spirited driving, replacement synchros were manufactured from brass with carbon sleeves.
