Our ultralight final drives to be screwed to our LSD for Peugeot-Citroen (PSA) MA boxes.
This final drive is the most recommended in combination with the original ratio and for use in rally, mountain trials, slalom, autocross, as it manages to reduce the maximum speed around 165- 175km/h depending on the rpm of engine and tire to use.
In the photos attached below is an example of a very common speed graph (7,500rpm and 15” asphalt tires) where we get a top speed of 169.50 km/h and another with the 13x64 group, where the top speed increases to 195 km/h, more interesting top speed for a circuit use.
