Thank you all!
I like this wheels very much so i would leave as they are now.
About the engine, this 335d chiptuning is very fast...it takes less 5sec. to reach 100km/h and reach 280Km/h very easy with 4 persons in board with the advantage of the medium consuption: 7,5l/100km.
I test already with some Posches like 911 C4 and C4S and this 335d is faster so i'm very happy with this beauty.
