The transmission of the Emira and Evora is slightly too long as standard. This is unnecessarily detrimental to the liveliness of the vehicle and thus the sporty driving experience.

The shortened JUBU axle ratio (semi-helical) corrects the unfavourable OEM ratio for all gears (1-6) and ensures a much livelier, sportier driving experience. Without any engine tuning, the vehicle feels approx. 25-30 hp more powerful.

Benefits

• Shortening of all gears (1-6), improving the standard gearbox (which is a little too long) to make the accelleration much sportier and the gear connections more harmonious
• Subjective (perceived) power increase of 25-30 hp - without engine tuning
• Permanent reinforcement of the gearbox

Details

• The crown wheel and the 2 pinion shafts are made from special steel that has been vacuum-melted twice and are designed for a torque of up to 700 Nm.
• The surface is superfinished and with grinded teeth
• The noise of our shorter final drive is slightly higher than that of the standard gearbox, as the helix angle and tooth mesh have been optimised for minimum of noise.
• High-strength motorsport quality with very elaborate surface treatment
• Manufactured on high-precision CNC machines
