I will order the Bilstein b8. I will mount them with the Eibach ProKit springs in order to have the B12 kit (or named PerformanceČ too). This kit seems to be a bit better than the BMW Perf' suspension but lower the car the same.
Not at all
It's only for the look of the car, these are not like holes on skirts on super cars
Before avec the Stage 1 chip, I drove like an old man
and have a consumption of 5.8L/100km (40.56mpg).
Now I have more power, I drive muche more faster and I have a less important consumption : 5.5L/100km (42.77mpg).
I tried to drive like I drove before and I reached 4.8L/100km (49mpg)
I really would like to have another motor, but I can't
