'Corrosion' that's pretty funny
The rotor hubs and calipers on my new 328ix were rusted and looked like shit 5 months after I bought the car new.
I ended up having my calipers powdercoated Black. While in the dealer for maintenance, they had a new 6 series on the lift and they were painting the calipers/rotor hubs - when I asked, they stated the buyer was unhappy with the fact that the brakes rusted immediately and looked like shit - so he told them to fix the problem, or he was returning the car...
I just ordered a new set of crossdrilled/slotted rotors from ECS Tuning as seen here:
Didn't need rotors, I know that being crossdrilled/slotted don't really afford much of a braking difference on a street car - but I simply like the looks
At $149 for the front Pr + $129 for the rear Pr - can't go wrong. I'll be posting up pics as soon as I get them installed...
