hi all, I have had this "strange idea". As the mondial main default is its big weight, why not pull out this big steel protection plates under the car. ok, we dont have the protection function anymore, but I think it would dramatically enlight the car : probably 200kg. this would make the car weight something like 1300kg, which would be better than 50 more HP. I will look under the car next time it goes to the workshop, and ask my mechanician if it is possible.
