That's because they weren't available for yours. They were only an option on the 996 C2S.

I blip downshift to rev match the RPM's, assuming that save the clutch and wear and tear on the transmission. I don't really heel toe it, any advantage if your not on the track?

My mechanic said something similar, but mine sees a fair amount of traffic. I do question really it's better to keep the RPMs up even when it's in first gear in stop and go traffic. I asked him specifically about this and he didn't change his answer.

He suggested keep it under 3K when warming up, and upshifts should be done in the 4-6K range.

In my imagination, I'm always on the track

No, I cannot think of any advantage - other than the selfish pleasure it brings.

I started practicing rev matching downshifting about six months ago with my 330CI and 986 Boxster. I'm pretty good at it now but find the 996 harder. I find I have to depress the accelerator further than the other cars. Anyone else experience this?

What's with all this shifting and braking baloney? Why wear out tranny, clutch, or brakes?

Just toss out the road anchor.

Downshifting puts the braking/drag at the rear, helping to keep the car aligned with desired direction of travel in conditions that warrant.

Not especially needed with ABS....

Downshifting is cleaner, at the rate my pads make a mess. Hell i can barely leave the driveway without brake dust!

Think of all the heat your brakes generate instead being transferred through your clutch and transmission. The only real case for compression braking is on steep downhill grades, and even then you should be rev matching your downshifts and just using the engine braking to hold speed.

Or not. These clutches are pretty solid and if done properly down shifting places no additional wear on the them than any other gear change. Riding the clutch or dropping the clutch is what shortens their lifespan.

Brakes are for slowing the car, transmissions are used to accelerate the car. Case closed.
