Porsche 981 wind buffet diffuser

Porsche 718/981/991 suffer from intense wind buffeting when driving at highway speed with one or both windows down. There are a couple products on the market but I decided to design my own.

This has only been test fitted on my personal 2014 981 but it should fit any 718/981/991.

The 981_buffet.stl part is meant to be printed with 0% infill and cut apart to form the left and right parts. This is because the finished parts are a bit too flimsy to print separately. I used the printed part just as a fit check and to see if it was effective before continuing on to carbon but you could sand/paint it and use it as the final product. I used 2 outlines and the parts handled 85mph no problem.

For those who want a more durable/aesthetic product, I've included 981_buffet_mold.stl. This can be printed and polished to use as a mold for carbon fiber or fiber glass vacuum bag fabrication. Highly recommend printing in ABS as epoxy aggressively sticks to PLA and even with mold release th
