Samsona's Subaru Impreza STI 5 or 6 speed gearbox kit

This gear kit was specially developed for the Subaru Impreza STI and is used in the original gearbox
 Designed for rally, drag racing or normal road use.
 The production and distribution of Samsonas is in Lithuania, therefore spare parts are available within a short time and extremely inexpensive. The optional gear lever is completely CNC milled. Sensors are used by KA and Variohm (both suppliers to Formula 1 and Moto GP).
 Various gear ratios are available for the gear kit. We have developed a transmission simulation tool to design the optimal gear ratio. In a simple variant, create plots of speeds, axis torques, accelerations and much more for every possible translation. We also calculate the optimal gear shift speeds depending on the gear ratio and gear. This enables us to calculate and deliver the optimal translation for the fastest sprint and lap times.
 In order to fully exploit the advantages of a sequential transmission, we recommend a freely programmable control unit from MoTeC or Link ECU. We program this so that the ignition and / or injection is interrupted when switching. This enables upshifting under constant full throttle, without using the clutch. Downshifting with automatic double-declutching is also possible. With the correct design of the drive train, even without coupling.
 If you are already using a freely programmable control device with Gearcut function, we will coordinate this accordingly. If you do not yet have a suitable control unit, we will be happy to advise you on the different variants and options of MoTec and Link ECU control units. Simply contact us for this. We also carry out motorsport cabling according to Mil specifications and coordination on our high Dynapack dynamometer in-house.
 We would be happy to advise you by e-mail, by phone or personally (with advance notice) at autobau Romanshorn.
