just throwing this out there as an idea.
what if naca ducts and some tubing were installed on the rear clam itself to provide some airflow to vent the rear end.
I have a home made brake duct venting system on the spec 944 i just bought, and the previos owner says it makes a huge difference. maybe something simple like this could be applied in this instant as well.

also just another reason to have a firesuit/gloves on while you are on track..........the unforseen can happen, and fire is a bitch that does not discriminate between burning your car or you.
