So yes I'm sure it is the correct one. Keep in mind that these are for the lower two spots under the actual dash. If you are looking for something that fits in the dash where the radio or the climate control usually go then these are probably not what you're looking for. I'm not sure they make anything to go in the actual dash openings.
If the cup holders are above the radio in the car then you could probably move the climate controls to the cup holder spot and put a cubby in the climate control spot. You would have to find the correct bezel to fit around the climate control though. If you search Boxster 986 interiors you will see pics of what I'm talking about.
