...but they sure last pretty good.

5 years, 40k miles, a dozen or so track days and they still have some tread left.

Last outing for them tomorrow, then it’s time for some new ones - 5 years is plenty old enough for track use, even though the car doesn’t work them very hard. Not sure what I’ll replace them with: pretty much anything would be stickier, but I don’t really care about lap times, and I don’t want to compromise the progressive breakaway which is the car’s great charm.

Also, apparently to cats an open engine bay is just an invitation to explore.
