Was just at Fuji 6 hours in Japan. The diffuser has been used by some Carrera cup and Gt3 amateur racers according to a Porsche Motorsport rep. He said heat needs to dissipate from trans cooler on PDK. Saw a few cup cars here with R diffuser with drilled holes under trans cooler for heat escape.

Highlight was being a passenger on R8 pace car in the rain day after the race.

Shame about all the rain; dreadful "race" for the fans.

More cooling, more betterer.

It was a bitter cold rain. Crowds was sparse all weekend. Still a great event, also toured the paddocks and got close to all the prototypes.

I was in Chicago last weekend and arranged my weekend plans to facilitate watching a 6 hour "race" from 9 PM - 3 AM local time.

I am quite displeased with the stubborn FIA Blue Blazer mentality of having a race at Fuji in October; it was essentially rained out in 2013, and F1 has encountered rain issues racing at Fuji in the past, as well.

Alas, Toyota owns the track...

I went to the bulk of the IMSA calendar this year (8 of 12 races) and the WEC round in Austin; I had the opportunity to spend the final 30 minutes of the race in the Porsche LMP1 pit garage - very special.

October is generally a drier month in Asia. All week until Friday, the weather was mild and dry. Besides Le Mans, there seems to be less interest in endurance racing.

Thanks for the help!

can you clarify... MR confirmed it needs or does NOT need the diffusor to have the cutout?

They said it don't need it.

But as stated earlier: wonder if there is a cut out in the diffuser for the PDK 991.2 GT3.

It makes sense! Maybe.
In any case, we both have straight installation from MR without drole or cut, i believe they control PDK temperature while tracking hard the car before making this choice.

This is from the GMG thread.. doesn't look like any cuts or drilled holes for the .2
