Does anybody know why there's a golden coating at McLaren's rear suspension structure? I guess it's because of friction, or maybe heat reflection, as it is only at the rear, but not sure.
It is gold foil for heat reflection and it was first used by Ferrari some 4-5 seasons ago (if not more) to protect suspension arms from heat since on one race (Monaco I think) exhaust "killed" suspension on Schuey's car.
