Your dog gearbox champion in Uruguay

We won the championship!!! Your gearbox helped us a lot to do it, really. The major change the car has, was when we start to use it. It was the best investment we did in the car, by far. Thank you very much!!

Bollverk dog gearbox

I want to share our happiness with you. Since we change final drive to 6.333 as per your advise, we won the last 2 races of Uruguaian championship. The last one was incredible. Traditionaly it is the toughest rally here, and the car suffers a lot. Because a mistake we made, we lost the first place with only 2 stages remaining. We run as never, and the car stand the punishment, and finally we win the rally for 3 seconds. Now we are leading the championship with only 2 races to finish. Really I have to thank you for the excellent gearbox you make, and obviously for your advise. We should had listened to you earlier.
