Hello i recive recently my black series, in the firts times i liked to tuning and increase the power, But afther a 1000 km running and some tracks, I thing it,s mutch better to lower the wheigth to have a perfect car, anny sugestion?
In my opinion the actualy 1550 kg it,s a fantastic performance for mercedes, but tis car with 1400 kg o lower can be crazy........
Please ideas?

Not many weight saving options in the SLS BS, unless you want to gut the interior, especially since I assume you are European and already have the lighter weight Euro seats. The car already comes with a carbon fiber hood and carbon ceramic rotors. You migt be able to cut a couple pounds per wheel by going with some aftermarket forged wheels, the factory wheels are forged but they are some of the heaviest forged wheels I have seen. An EcU tune will onlynet you about 20whp, I started off with a custom dyno tune from Weistec before I installed my Weistec Supercharger. A supercharger is the only way you will see any major gains with this car.

Thanks for your information, but in my opinion 150 kg less are better 150 hp more, and in this car more,
I like to try to less weigth....

I do not think you will find 150kg/330lbs of weight reduction in this car unless you want to remove radio, ac, carpet and passanger seat. Furthermore 150kg/330lbs reduction in weight will only net you about the equivalent on 30hp. Good luck...

Thanks sure you are mutch more experience....
