I have a set 2+2 Urethane Kaminari Door Fillers. They were never fitted to my car and are not painted. So they can be paint to suit your car. I can supply the Kaminari side skirts that make these a matching set. (In Fibre Glass). Price $200.00 + postage. PM me if interested
Still for sale. No the sides are priced separately from the filler. So yes $450 for sides (fibre Glass) door fillers are rubber.
