VISUEL SLR90-20

SLR90-20 TRANSAXLE

Specially designed for Circuit, GT and Single Seater racing, the SLR90-20 combines innovation and optimized architecture.

We set out to create an all new transmission with these key changes in mind: reduction and better distribution of masses, smaller dimensions, robustness and improved capacity, the SLR90-20 is tailored to the current needs of the targeted disciplines. 

Its design is daring : our design department has opted for a rear differential to grant a better weight distribution. And, as far as the driver safety is a priority for SADEV, our designers have studied extensively the casings so that a larger rear crash box can be integrated and meet the LMP requirements.
