2007 Porsche Cayman — first HPDE in a stock street car

HighwayRoadieCommunity StarterApr 10, 20262007 Porsche Cayman SRaleigh

I am doing my first beginner track day and do not care about lap records. Besides fresh brake fluid, enough pad, good tires and torque checks, what is truly necessary versus internet overkill? Mileage is about 81,000.

I would start here: measure it if you can. Two cars can feel identical and have different causes. That is from a 2007 Porsche Cayman in Raleigh, so take the climate with a grain of salt.

Before you spend money, capture when the 2007 Porsche Cayman does it — temp, speed, and whether it is in gear — before replacing parts.
