Other C6x gearboxes, such as the C60 and C63, are used in conjunction with the ZZ-series engine in cars such as the Toyota Celica. The C60 features identical 1st-5th ratios and final drive, but with a longer 6th gear, while the C63 features a completely different gearset (other than 1st) and longer final drive, reducing acceleration but increasing in gear speeds.

====Known Issues====

There have been reports of a weakness in the syncro-mesh in the C64 gearbox on 3rd and 4th gear. Changing the [[Gearbox_oil#Toyota_C64|gearbox oil]] and engine mounts has been observed in some cases to cure or lessen this issue: http://forums.seloc.org/viewthread.php?tid=311604

In the event of a gearbox failure (or if increasing power or planning on using the car heavily on track) then it is highly worth considering the stronger [http://www.hangar111.com/web-store/lotus-2-eleven-gearbox-a-clutch/445-toyota-elise-exige-2-eleven-jubu-racing-gearset-2zz-c64-gearbox.html Jubu Racing Gearset] for a rebuild, along with an gearbox oil cooler to reduce gearbox temperatures.
