Hi I have a yellow Boxster also and the guy I bought it from had installed the aerokit but not the back spoiler. He did give it to me not painted. I am debating if I should or shouldn't install it. Do you have before and after pictures of your car. Or else maybe a closeup of where it should be installed. Lastly with this spoiler can the original pop up spoiler still be used. I think it is aerokit II where it needs to be shut off.
TIA
Sal
