just got a panni and installed the booster seats in the rear for our 7 and 5 year old daughters.

In the Panni the rear seats have the headrest built into the seat vs my mercedes e (replaced with panni) and mercedes s both have collapsible head rest and the boosters seats fit fine. The booster seat top rest against the top of the rear seat. I called a couple of porsche dealerships and they did not have an answer.

Anyone install boosters seats for their kids ???

I am spending way too much time on this board. Good luck with it; I'll be needing this answer in a year!

 

thanks again
