Never double clutching, usually heel and toeing and always rev matching down shifts to slow - rarely using brakes, and the clutch on my Z lasted 74,000 miles. That's good enough. Only one pad change in 96,000 miles. Porsche is even easier on clutch with 6 gears rather than 4.

How does the number of gears make it easier or harder on the clutch?

The rpm difference between gears is smaller with more gears so rev matching is much easier. A littler more precision is easier on the clutch.

Not nice to torment parked cars.

Downshifting from 4 to 3, matching revs, and engine braking does not put any additional stress or wear on the clutch.

I'm not talking about the friction surfaces genius! Read again what I wrote.

74K miles in not good enough. I went 345000kms on a same clutch without doing any of this nonsense. eventually the flywheel diaphragm fingers wore thought the release bearing, the disk was still ok.

​​​​​​As I understood what you wrote, you stated engine braking impacts clutch wear. If I misunderstood or my reading comprehension needs help, I'll own that.

If you're suggesting engine braking, in any way, impacts clutch life, you're wrong.

you guys need to define what you are talking about, engine braking or clutch braking.

my old 850turbo track beater had well over a half million kms on the original clutch, my latest choice of clutch setup on GT2 has a year of driving on it and didn't even have dust on it when I pulled it apart for my winter build this year, literally looks as I had installed it....I have a customer who I replace his clutch yearly...
It's all how how you drive it off the line, you can drive HARD without doing any wear to a clutch

What do you think happens to the springs during engine braking?

If you're fully off the clutch, nothing. It's no different than letting off the throttle pedal driving down the road.
