We have certainly kept to that rule, as the six-speed manual gearbox in the new 911 GT3 has been designed especially for the high demands of motorsport. This lightweight gearbox is highly efficient and the gear-lever throw is short and precise, enabling fast and accurate gearshifts. In conjunction with the friction-optimised and lighter dual-mass fly-wheel, the gearbox provides an extremely high level of precision and capacity.
The gear ratios are perfectly matched to the 3.8-litre engine to enable even more dynamic power development.
Robust steel heat-resistant baulk rings on gears three to five ensure a precise gearshift action even under extreme loads. Cooling is provided by an additional oil-to-water heat exchanger and spray lubrication. Both of these features are essential for durability in endurance racing conditions.
