We have installed and used these shifters and cables for months now and have had not issues considering NVH. They are a nice part - keep in mind the cables come with a small press in that goes on the end links. I know some folks installed the cables with out the "bushings" and that cause issues.

Hope that helps. We enjoy the notchy feeling when driving and its such a nice piece.

 

yes there was a guy that didn't put on the little plastic pieces and he was basically saying that the noise was so loud that it precluded normal conversation. Perhaps he was exaggerating, lol. But anyway, rest assured that the nvh is not intolerable. I suppose there is a certain amount of break-in, or adjustment before things settle into final position - Steve I wouldn't take the cable out right away if you aren't sure. Give it a week or 2. I realize it's a lot less convenient, but there's no doubt that there was a sort of "bedding in" period. I realize that's not an accurate term (it refers to brakes), but I hope the point is clear...

 

Cannga,

Tranny is out...no better time then the present to upgrade!

Numeric shifter will be installed by the end of the week. However, I have opted to go with 996 CUP Cables! As well as lots of 999 Porsche Motorsport Clutch & assembly parts.

Couple all this with an Aasco Aluminum Fly Wheel & GMG tranny urethane mounts. Hopefully this will prove to be a recipe that can handle the rigors of real track work.

 

I had the Aasco on my 997TT - it's a little noisy, but revs matching is very easy.

 

Bob, my car is noisy, period! I don't think I'll notice much of a difference. However, I'm sure I will be able to pickup some minor audible differences. My exhaust pretty much neutralizes everything in my cabin. Not to mention, the widows are usually down and a helmet it on!

 

D, does your car still have the hydraulic assist in the clutch?

 

Bob,

Interesting you mentioned this. This was brought up in our meeting this evening and they will be researching options tomorrow. So, yes...as of now it does have hydraulic assist.

Can you offer any insight to this? Obviously you know some thing since you brought it up.

Many thanks in advance.

D,

My clutch setup was a Sachs 2 clutch, 764 pressure plate, and an Aasco LWFW. When my car was at Ruf, they found that my slave was leaking, so we discussed doing a GT2 hydraulic conversion. I opted against it and had it replaced under warranty.

When I got the car, I liked the setup, but found the engagement to be a little high, and the hydraulic assist made finding the engagement difficult. The "range" of engagement was very narrow, much more on/off.

In comparison to my friends 997TT, which was the same clutch setup with a GT2 slave conversion, I found the engagement much more temperamental with the hydraulic assist because engagement was more touchy.

If I had to do it again, I'd do the hydraulic delete. I use my GT2 as a daily driver and find the pedal effort gives you much better feel.

Can - sorry for the hijack.

Bob,

Thanks. I am 100% positive Can will not consider this thread "hijacked" in his never ending quest for knowledge! Its the sum of all that makes it complete.

 

When I compare my original OEM clutch + hydraulic assist versus my Sachs 2/764/Aasco setup + hydraulic, I found that the engagement point (much higher) and the engagement range (much shorter) were the biggest issues. The hydraulic delete makes engagement much easier to "feel." The increased effort took about a week to get used to in my GT2, but I should have opted for it when Ruf suggested it.

 

VID & Bob, absolutely no problem at all. Have you not seen what's going in my Cargraphic thread? Even *that* doesn't bother me; the more the merrier. (Wait... why is it all quiet there now? Bob, did you send out some police-type cease and desist warning? )


VID is there anything you don't have? :-) I wasn't surprised you were already onto the Numeric stuff.

 

Thanks Chris for your feedback. A few questions please (anyone else feel free to chime in as needed):

1. Do you *always* install both Numeric shifter and Numeric cable, or do you sometimes just change shifter alone?

2. Are you familiar with the Porsche OEM SSK? How does Numeric shifter's throw compare to SSK throw? Shorter or longer or same? The throw of the OEM SSK is perfect for me and I am not looking to change that.

3. What I *am* looking for is a more solid and precise feel. More metallic, less rubber. Would switching from OEM SSK to Numeric shifter (without cable change) enough of a change to improve this?

4. Please explain what you meant by "notchy" above? That is not neceessarily good is it? Thanks.

1. We have installed each item separately and seen positive results.

2.You can actually adjust the length of the throw so that's a plus.

3.What you are describing in my opinion is the NR SSK.

4. Mechanical is a better way to describe over notchy.

 

Cannga,

I drove a 775 TT not to long ago with a OEM SSK. I did not care for it and I did not like how low the shifter sat in the console. I'll be having the Numeric set-up in the standard throw/height position.

 

OMG I almost fell off the chair laughing. So funny.

Yes please give your impression of the Numeric Shifter - don't worry about the noise assessment part; I got the picture (still laughing when I type this LOL).
