PRY! Take a rag, double it up and set it on the argent part of the wheel. Slide the screw driver into the tiny bent grooves on the GT Hub and GENTLY tap until you hear the side pop a bit. Move to the next grove working in a circle until it comes off.
Think of it like taking off a paint lid. You just work around in circles taking care not to ding or scratch until it comes off.

P.S My car has been removed of all chrome and acessories for it's Gulfstream Aqua paint job on Tuesday. I'll post pictures.
