i still don't know, will this work for a 997 as well?

Don't know what? If you'll do it or not? Not sure about the 997, but I'm assuming that there's got to be an analog process. Maybe it's different spring, maybe it's the same, I honestly have no idea.

What I will say though is that for a 996 Turbo with a GT2 slave cylinder setup, this mod had a very minor impact on the clutch stiffness, but with my extremely grippy ERP carbon clutch, every little bit helps in feeling the engagement point.

There were a few folks who swapped it with the spring itself from the 997 (not the whole assembly.) They much preferred it over the stock spring in the 996.

Having said that, the 997 also has this spring helper so yes, it can be removed and re-installed upon personal preferences.

well, i don't know if it will work in a 997...if it does, i will do it, or maybe have it done, i'm getting old and kindof un/inflexible...

ahh, ok , i read this after replying to the previous post, so i am going to see if i can find someone to do this , anyone know of a good mechanic in solingen...?

I just did this mod using the McMaster-Carr spring. The result was a HUGE improvement in feel with only a minor increase in clutch effort. I can now feel and modulate the engagement point where, with the stock spring, I felt I was always just guessing. In fact, with the old spring it seemed the engagement point was always moving around and extremely nonlinear in its rate of take-up. With the lighter spring, everything is firmer and I can launch with a lot more confidence. My mechanic drove it and said it was much more "997-like."

Anyway, those are my two cents. Highly recommended.

Geez, time flies!

It's been over 7 years since I started this thread and haven't yet done this mod on my 996TT yet.

I really don't like the thought of nearly throwing up and getting dizzy, and thankfully the TT clutch stock is much better than the N/A one. But I'm sure this mod will make the TT feel even better so it will be on my to do list.

I just ordered the McMaster 9657k142 springs for this mod. 6 are coming. If anyone needs one let me know.
I have been using the Home Depot spring for a while and am hoping the new springs will provide more "help".

still waiting...

Absolutely! I agree completely. When I originally posted my complaint was 2-fold: The clutch was extremely heavy (turns out that the disc was down to the rivets) and the vague feel on engagement. I used the McMaster-Carr spring as well, and now the improvement on feel is huge.

For those that changed the spring to a lighter one, what's the best way to get the old spring out of the housing (by releasing the pin/nail) without it flying out and hurting someone??

I put it SECURELY in a large vise, and then used slowly opened the vise to release the spring compression.

AndyK

Makes sense, except the rod sticks out of the spring housing - how do you clamp the vice around the rod?

frisbee91

Hmmm. I know I used my vise, but it's been a few years.

I think I just used two blocks of wood to support the round housing on either side of the rod.

So I put in the McMaster 9657k142 spring. As far as I can tell, its the best alternative out there. I have tried:
1) The original OEM spring - maybe too much help, hard to get the feel of the clutch
2) No spring at all - I think I ripped a groin muscle because of this
3) The Home Depot spring - Still pretty heavy but good feel
4) The McMaster 9657k142 - Nice balance between effort and feel; feels well balanced with the accelerator.

I'm sending out my extra McMaster springs to anyone that asks. If anyone still needs one, I have one that is not claimed.
