2008 Cayman S and 2010 GT3
Joe Gibbs oil is THE best shtuff... and the 3rd radiator big plus... those two items alone reduce temps/friction... noticeable tooI have 140k on my 07 cayman S. I daily drive mine and still love every minute of it. I do my own oil changes at 5k with joe gibbs oil. I do most of my own maintenance. I’ve done brakes, plugs and coils, AOS, headers, power steering pulley and belt, cold air filter, 3rd radiator and other misc stuff. If I don’t feel like it I have a good honest independent Porsche specialist.
Mods include: LN engineering oil filter, EPL headers, “RS 370 kit”, tune and cold air, R suspension, 3rd radiator, numeric short shifter and cable.
I have a lower thermostat and water pump waiting but I’m still on the same pump! I have gone through 2 AOS, passenger window switch and engine mounts. I upgraded all mounts to semi solid and haven’t looked back. Car runs amazing. More reliable then my 2012 Escalade. I bought the cayman with 50k miles on it. Buy the car and drive the piss out of it. The maintenance is no more than a bmw.
