[968TDG]

I switch between driving two manual cars, the 968, and a Subaru Legacy 2.5gt. I'm try to make the 968 a bit more of a pleasure to drive, and the two things that get tiring after a while on the Porsche are the long shifter throws and the long clutch throw. I'm ordering a short shifter kit from RSbarn, but as for the clutch throw, is there any adjustment that can be made to decrease the length of the pedal throw? It really is a full leg movement every time I shift, easily twice that of the Subaru.

Another note is that, while Flash got in the car and pressed the clutch and told me what type of clutch I have installed, I can't remember what he said, but I believe it was not the stock clutch plate.

Thanks -Phil

Hmmm... I've never noticed that the clutch throw is inordinately long. Anybody else of this opinion? The stock shifter, on the other hand, is beyond ridiculous...

as i remember it felt like you had the pressure plate that a lot of vendors sell, which is NOT the original one, but intended to be used as that one - the problem is the pivot geometry is somehow not the same - the result is the sensation of going over a steep hill with the pedal, rather than a smooth progression

as for the throw, you should be able to begin to engage the clutch a bit more than an inch down in travel - release should begin a bit more than an inch from the floor - how much pedal you have to use will be dependent on factors like which gear you are in and the rpms going in and coming out

the fork bearing will have a LOT to do with this geometry too - a worn fork bearing will translate to a significant increase in required pedal pressure and change to the progression of the pedal, and even a "notchy" feel

the high pressure hose can affect this too - an OEM rubber hose expands, even when new - this translates to a softer pedal and more travel

Looks like you have some places to start Phil, but fwiw I have the same basic sensation driving my RX8 daily and the 968 on the wkends. Bob yells at me to "let out the clutch!" so clearly there is a driver input issue here, but I find that I can place the throttle and clutch exactly where I want when I want, in heavy traffic, blitzkreiging an entrance ramp, or hammering an apex in the RX8 with almost no thought, while I have to pay attention in the 968. Probably more a time in seat thing than any thing else.

I'll be replacing the hose soon with a stainless hose, though I did find record that the hose burst on the previous owner about 4 years ago, and was replaced, though with the OEM rubber type.

I guess I'm accustomed to needing to press the clutch almost all the way to the ground from my past cars. I haven't grinded the gears yet on the 968, but I haven't really messed around very much with depressing the clutch much less than the full length of travel.

Pedal force always makes things more noticeable as well I'm sure. I need to look for the access point for the fork bearing so I can try to lubricate it.

Is the clutch spring, attached to the pedal, supposed to overcenter when the pedal is in the up position? I assume so, I just noticed it while I was in the foot well looking at the travel. This gives the pedal a bit of a transitional feel right at the beginning of the throw where the spring is overcentering and the pressure is beginning to build from the hydraulic system.

Also I do have a system fitted to prevent the firewall flex, so this is no longer a factor, though it used to be a major one, extending the two step feel of the pedal throw, increasing the gap between the force from the pedal mounted spring and the hydraulic system.

Thanks for the input Rxter, I'm sure brand to brand there is just a learning curve for how to really use the car.

there is no access point - unfortunately to adequately lube the bearing you need to remove the fork, which means removing the clutch

there is a diagram in the workshop manual for the clutch spring adjustment that will probably answer that question better than i could say it
