I bought a 9000 aero a couple of months back, and for a 150 mph car - or even a 50 mph car (!), the headlamps were pathetic! I've now fitted a set of these re-furbished reflectors along with Osram NightBreaker bulbs, and the difference is dramatic! I can now see where I'm going at night! The performance of the headlights now matches that of the car! Highly recommended!
