The child seats are designed for your Porshce. The seat will work well for your son. But there is one other design feature for the Porsche child seats. You can have the child seat in front as it has a connection that disconnects the passenger airbag so a child can sit in front with you. I have used it in the 996 it comes in handy for me as I have two children. Check with your dealer it comes in three sizes.
