Project 987.2 Cayman S: Cooling for the Track Part 2 with Bilt Racing Service

A cool feature of the BRS pan is the filter for the transmission can now be removed and cheaply replaced.  The OEM pan has a built-in filter which means the entire pan has to be replaced when servicing the transmission.  This is expensive!

The BRS engine oil cooler kit comes with a remote power steering cooler. The OEM power steering is cooled by the same tiny cooler that also cools the engine oil.  The BRS kit not only changes this for a much bigger engine oil cooler, but it also bypasses the power steering fluid and routes it to an air to oil cooler in front of the left-hand radiator.   This not only cools the power steering system better but it also reduces the heat that the power steering can introduce to the engine oil and the coolant.

The stock PDK cooler is a tiny oil to air part that is inadequate for track driving.  The PDK transmission overheats and the car goes into limp mode at the end of the session on a hot day.  We are replacing it with this huge BRS unit that is over 2x the size of stock.  This looks to be the same size as the part on the GT3 RS.

The cooler kits come with quality fittings for the coolers and the power steering cooler bypass.

To get to everything, we had to remove the rear chassis braces. As a note Porsche recommends that if you remove this stuff the rear alignment should be checked and adjusted in needed afterward.


  1. Do you know if both the BRS side mount cooler and the BGB cooler can be installed? Or do they both cool the same (clutch?) oil?

    1. One cools the tranny and the other the differential. Since we are not running a LSD yet, I didn’t think we needed a cooler after talking to guys who race these cars.

  2. How did the intake manifold fit? It doesn’t seem like there is enough room for the larger oil heat exchanger. Also how far does the oil pan hang down front to rear?

  3. Great series on a great car. I’d love to see some before and after temperature data of the engine oil, pdk, and coolant system after all this work. I’d like to lower my own temperatures but it’s hard to know how much needs to be done to achieve reasonable temperatures.

    1. We didn’t take any before but these cars are known to go into limp mode in just a few laps with a fast driver due to the PDK overheating. Ford Factory driver, Billy Johnson drove the car for a full session on a hot day with no issues, tuning a 1:57 at Buttonwillow.

  4. Now that it’s been a couple years, how is the cooling on the 987. 2 working out on the track? I’m considering buying a 987.2 Cayman S and my only major concerns are the cooling and reliability of the PDK on the track (which I feel is related to keeping it cool)
