I've got the bottom of my wheel done gloss black, there's just four torx screws at the back of the plastic which are situated in long collars that once the screws are removed need to be pulled away from each other. There's also tiny wedges on the plastic that helps lock it in. Be careful after the screws have been removed as I managed to break three of the four screw collars. Once the screws are out and the bits around the bottom edge are free pull the front plastic section away from the wheel towards you until the collars are free from each other. You'll know what I mean when you remove it.Did you do the steering wheel too? The bit at the bottom? I want to do mine but dont know how it comes off
