The best advice I got from an og HPDE PCA member was ask around and find a local shop if you can that services Porsches that see -all levels of use-… from collector cars and garage queens to daily drivers all the way up to occasional track days and full blown Cup Cars.
They will generally be staffed by former Porsche mechanics, provide at the bare minimum an equal and more tailored and personal experience than a dealership… and will most likely be cheaper in the long run.
I try to think of maintenance and performance as synonymous… and with how I push my car I want to know that it is going to do exactly what I expect and intend to… which means knowing I can rely on the state and performance of the various regularly replaceable parts (rubber, brakes, fluids, filters…) and I equate it to confidence and peace of mind when driving… much more so than in a non-performance car doing non-performance driving
I get into my shop often, I stagger my services so it’s never all at once… I get fluid analysis done every time… keep my rotors fresh… and generally stick to the Porsche script but in some cases let things go (if the fluids look fine)… but in other cases I go way over what Porsche recommends (e.g.: they say 10k for oil… I feel better going for 6-7k. And I do my brake fluid more frequently)
Overall the car has been incredibly… quite honestly I am -amazed- beyond what I would ever have expected the performance and reliability to be over these last few years.
But the relationship I have with my workshop now is a LOT different than decades ago driving my Camry… as in I have no clue who any of those guys were… and I’ve been forced to become friends with my Porsche mechanics just on the basis of how often we see each other 😅
