Actually, based on this: http://www.ft86club.com/forums/showp...69&postcount=3

It looks like it's just a dead zone built in by the ECU reset that's supposed to go away over use, and can be sped along by engaging the throttle without the engine on repeatedly.

Am I mistaken, then, in thinking that a CDV only affects RELEASING the clutch pedal, the clutch engagement?

What you're saying here suggests that the CDV affects the clutch DISengagement as well, so that a fast shift might "beat" the clutch disengagement, which of course would result in gears grinding.

If so, I don't like the sound of that. :(

I like all the Pumas I've tried for driving, but I do tend to gravitate towards their motorsport-inspired ones moreso than their others. Probably my favorite pair for driving is my pair of Drift Cat 4s, which are (sadly) just about worn out - I might have to buy a new pair before this summer.

My understanding (and the wiki page on CDVs) is that they are a one way valve that limits the rate of clutch engagement, but it does not affect clutch disengagement in any way. This is definitely true on BMW's clutch delay valves as well, from what I can find. That having been said, I can't find much on whether or not the BRZ/FRS has a CDV, and if so, how it is set up, so it could be set up differently from the standard arrangement. I can't imagine they would delay the disengagement of the clutch though - that would increase clutch and transmission wear for no apparent benefit.

Exactly. One-way. That was my understanding, but I never actually examined the system in detail, but just assumed this to be the case.

Me either.

But, these days Interstate bridges fall into the Mississippi, so...

God knows what they're up to.

I'm very pleased with my Piloti shoes.

They have nice details, like rubber reinforcement on the right side of the right shoe for heel-and-toe. They're designed expressly as performance driving shoes, and with sufficient sole padding that one can comfortably walk a good ways in them unlike some dedicated racing shoes which look a bit too lightweight and in which I wouldn't want to walk home from halfway around the Nürburgring. ;)

I bought mine from Pegasus Racing.

I'm looking for a good pair of shoes that will look good in the workplace, where normal professional dress is a neat button down untucked short sleeve w/ jeans or dockers.

My loafers are good for that, but a little too loose in the heel for driving with all the time (the back of my ankle on my left foot gets majorly tender).

I also have narrow feet, so I need something that fits, but isn't so foot - conforming that the sole is too narrow (even with the cusco accelerator pedal, my jazz sneakers are too narrow for secure heel-toe purchase).

I'll look at the drift cat 5's. I just need to find a store around here that has them so I can try them on & see if my normal size (8.5 or 9) is appropriate.

Oh, I forgot to mention this: The Piloti shoes employ a tread pattern that duplicates the old '60s ubiquitous Dunlop road racing tires tread.

Is that cool, or what? :eyebulge:

I've found that they tend to run a bit small, so you may need to go up half a size from your normal (depending on what your normal is). It's probably worth trying on to be sure though.

That is pretty cool. I'll have to look into them

Pegasus racing is out of ALL piloti driving shoes in anything like a normal men's size.

Properly designed driving shoes employ a rounded, cupped heel intended to comfortably support your foot as it rests on the heel for long periods as it would when driving a car. My Piloti shoes are very comfortable for driving while still being functional and comfortable to run around to stores running my errands. I see fellow photographers wearing them as they traverse the very rough and rocky terrain around the perimeter of race tracks.

They're worth taking a good look at.

My Pilotis are size US 9, and they work perfectly with my S2000 and my BRZ without any pedal modifications. That doesn't assure that they'll work equally well for you, but they're worth a look.

Bummer.

Maybe you can find them elsewhere? They used to be priced similarly to the Pumas.

I was looking on Piloti's website and I LIKE what I see. Wasn't sure which Pumas I'd want, but the Pilotis look ideal.

These would be great for office, church, and general wear (like my loafers) in terms of style, and they have all the nice benefits of the driving shoe that I want (including that cupped heel): http://piloti.com/product/trazione-3/
