Additional Information

Why choose BMW gearboxes?

Availability and price. Millions of cars produced and their worldwide availability guarantee the accessibility of spare parts. Both individual parts and complete transmissions are easily available at authorized dealers (ASO) and on the secondary market.

Durability and reliability. BMW ZF / Getrag gearboxes have been successfully used for many years in both amateur and professional motorsport. They can handle very high torque (some models 1000Nm+), while guaranteeing high reliability. They are ideal for SWAPs in high-power projects intended for daily use.

ZF Friedrichshafen GS6-53DZ

The ZF Friedrichshafen GS6-53DZ 6-speed manual gearbox (S6-53DZ) is an ideal solution for motorsport-prepared cars due to its high durability (1000Nm+) and low price. Input shaft spline type (Female): 32.5x35-26N

To mount the flywheel, it is necessary to use the flexplate from the automatic Mercedes-Benz version (OE 111-030-07-12). The clutch fork should be mounted on the lower release bearing position (in case of a two-position bearing).
