anytime!!
here in the middle east, to retrofit ceramic controls costs about $6,000. that is TEN times how much it would have costed to add the option before the car was manufactured.
personally, i couldn't justify it no matter how much i wanted them. instead, i decided to buy the front and rear idrive controllers in ceramic, alongside a wooden gear selector lever (which attaches to the original part without additional ecu expense).
for $6000 you might want to consider:
-exhaust (eisenmann, dinan, supersprint, etc.)
-ecu tune (hartge, dinan, velos, active autowerke?, etc.)
finally, here's a better link for the m front bumper:
