But I bet no weight reduction, which is the important thing.

Outside of racing &c, how likely is it that a stock brake rotor is going to need replacing before the expected life of the car?

The 'expected' service life is based on the the sum of service lives of the various components. Are drums and rotors not consumables?

My Superbeetle was 40+ years old when I uprated the brakes.

Drums and rotors do have wear out measurements, a minimum thickness for rotors and drums a maximum diameter.
But most people don't bother to measure this when they replace pads or shoes.

I really want to do it now but the cheapest I can find the rotors, calipers and pads is about $3,400.
But the Jewish side if me can't let go of that much $.
Keep looking and maybe I can find a used set cheaper.

1+ frozen Rotors they also can provide the rotors if you are getting new.
I put a set on my 91 Dodge back at 280k .
You were saying life expectancy 3 sets of pads with surfacing between ea average . 2nd set of Rotors for this truck. With pads at ~40k intervals.

I often try to disregard the purchase price as long as the running costs are low, but with these even the running costs are high so no way worth it. Even if you get a lot of track time its not worth it. Just a race car novelty

But the average age of cars on the road today is less than a third of that: 11.5 years per this Average age of cars on U.S. roads breaks record So does it make sense to spend a lot of money to extend the lifespan of the brake rotors far beyond how long you'd expect the car to last? Especially if there's no other benefit?

Add to that the fact that most of us here should be using our brakes far less than the average driver.

Ha my car is already 28 years old.
I'm more interested in those rotors being larger and half the weight, lasting longer is just a side benefit.
When I hook the trailer up behind the car the brakes get a pretty good work out.

Many people still claim that drum brakes are "cheaper" and "longer-lasting", especially in the trucking industry. Maximum diameter? Sometimes they just put a thicker liner on it...

I can totally relate to that.

My trailer is getting drum brakes.
I really doubt that I will ever even wear out a pair of shoes unless something changes.

I think I'm going to start my eBay selling again so I can buy these and at the same time eliminate some of the stuff I'm not using.
