Does anyone happen to know what, if any, cooling measures were built into the GT4 clubsport for the transmission?

There's been a lot of discussion about PDK cooling in previous generation caymans and I wondered if the factory took measures to avoid the problems this time around.

Have not seen an issue with this unless there was an integrity issue with the cats...

Previous generations, 987.2, had issues on the track with the PDK (in sport plus) because of the LSD. They were in the same casing, separated by a thin wall. The LSD transferred its heat through that wall thereby affecting the temp of the PDK. This could partially be solved by overfilling the PDK and adding an additional cooler for the LSD fluid.
The cars that I'm aware off were all Cayman Rs (owned one myself). High summer OATs, high altitude tracks seemed to aggravate the issue. RMRPCA, for example, advised people participating in their events against the use of sport plus based on their experience.
In the 981 versions PAG applied lessons learned from what I've been told.

Doesn't the club sport use a 6 speed PDK and not the street 7 speed?

It's the same transmission except that the 7th gear is electronically locked out.

Thought it was the same trans as in the RS?

Nope. 2.7 Cayman with race ramp lsd

Thanks for the input. I haven't heard of any problems with the clubsports either and that was the basis for my question. I was trying to track down what changes may have been made to resolve the issue between the 987.2s and the 981s. I'm considering purchasing BGB's cooler setup for my 987.2, but I figured I'd try track down any other potential solutions first.

Have there been any issues with 981's being tracked with PDK?

Pulled off 6 events with my GT4CS this summer.
No problems with PDK cooling.
