e55 rotors and calipers
need at least 18" wheels and tires. Also, your current spare tire won't fit.
I think its MUCH too expensive.
Larger brakes won't decrease your stopping distance on the "Initial Stop",
only on subsequent stops (larger brakes dispense heat better). Stopping distance is a function of the tires and abs system.
What rims does he have? Do you know If the E55 will fit in 18' Brabus Rims?
Best Regards.
