I have an inspection the previous owner got saying inner and outer tie rods need replaced but he never did it.

The front shocks used a 22mm and rear used a 21mm.

I didn�t have a 21 and was tired of buying these sockets so I used a crows foot and counter hold tool.

I asked him to double check those numbers because they are way higher than what Porsche recommends for the factory Bilsteins (59 front and 43 rear).

Suggestion
I�d think that the near-double increase in torque that�s recommended by Koni on the front struts would have some sort of negative implication on these pieces.

Suggestion
Is there any chance that you could list the size of the special socket for tightening the shock nut as well as the various tightening torque figures that you used for all of the suspension pieces?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Greetings all,
The first part of my latest video series was dropped yesterday. If you've ever had interest in these shocks you should check out the video. I'm refreshing front and rear (front video first). Then I'll be taking it on the road (I live in Houston, so not very many curvy roads around here) to check out the handling. I've already driven her and w/o spoiling the results, I'm VERY happy. Check it out!

Thank you!
I'm planning on sticking my GoPro in the wheel well and drive it around for some good b-roll footage but then some dude named Nicholas decided to come visit and make everything wet.
Well done! Thanks for sharing, nice and soothing voice and fun to watch.
Just a suggestion add, torque specs in the vid and other required specs in the bottom or side or do a small frame showing it.
Excellent video, can't wait to see the rear shocks install; I am a Sub to your channel and really enjoyed all your DIY videos; thanks for sharing them... Cheers,
As a matter of fact I�ve got a video recorded covering the front drains and cleaning out the carnage. I covered the cabriolet drains in my convertible top videos.
Thanks for this video. I have these Special Actives sitting in their boxes in my garage just waiting to be installed. I just need to finish acquiring ($$$) all the other pieces.
Yogi. My 2002 cabriolet has almost the same mileage and I know it has had no suspension work in the past 8 years which means it has probably never had any. I have an inspection the previous owner got saying inner and outer tie rods need replaced but he never did it. I have those sitting on the bench waiting for the car's winter storage period. Now after watching your video I'm feeling like I should just do everything at once as you did. I know you haven't been shy about sharing your spending in the past - would you mind sharing a parts list / total bill for the refresh you did?
Is there any chance that you could list the size of the special socket for tightening the shock nut as well as the various tightening torque figures that you used for all of the suspension pieces? I hate to ask as you've already done so much with these videos but it would be incredibly helpful to me as well as the rest of the 996 community.
Koni shocks use a different sized nut than what The oem shocks used. On top of that, the rear are different that the front.
The front shocks used a 22mm and rear used a 21mm. I didn�t have a 21 and was tired of buying these sockets so I used a crows foot and counter hold tool.
PM me and I�ll hook you up with the workshop manuals. It�ll have all the torque specs you�ll need.
6 months later....
@Yogibara
Do you have any thoughts on things that you would have done differently, etc.?
I'm getting ready to dive into my full refresh including the Koni Special Actives.
Hey thanks for reaching out. The suspension is AWESOME. However, I probably have around 100-150 miles of drive time on them. Reason being, I'm rebuilding my engine. During the time I got to drive her, she was very responsive and turns were flat. Smooth highway ride and not jarring at all.
Oh I had forgotten about your engine mishap. Sorry to hear about that. Hopefully you�ll have her all back in one shape soon!
Thanks again for the vids; they are very helpful.
I'm about to blow some minds here but I just got off the phone with Koni North America and their technical service rep stated that the Special Active front strut piston rod/top mount torque is 92 ft-lbs (M14 thread with a lock nut) and the rear is 59 ft-lbs (M12 thread with a lock nut). I asked him to double check those numbers because they are way higher than what Porsche recommends for the factory Bilsteins (59 front and 43 rear). He reiterated that his numbers, found on the useless instructions that come with the Special Actives, are accurate.
Agreed on two parts. The instructions are absolutely useless and the torque specs given should be applied since the bolt and nut are a different size than OEM.
It does make me wonder, though. Clearly the Koni threaded piston can handle the higher torque specification as it�s designed for it, but what about the other Porsche components that interface with it? The rubber shims, the plastic shims, the strut bearings, and even the concave washers. I�d think that the near-double increase in torque that�s recommended by Koni on the front struts would have some sort of negative implication on these pieces.
I randomly stumbled across the Koni Special Active. I’m looking for something for my 03 C4S that would be more like a GT car, take out some harshness (speed bumps, expansion joints), but be properly sporty when asked. Assuming you’ve gotten to put some miles on them, would you say these fit the bill? I’m actually in the Sugar Land area, so probably similar roads as you, nothing terrible.
Will do, thanks! I was looking at building an MO30 setup, but I keep reading that people feel it's too firm. I don't plan on tracking or autocrossing (that's what the GTI is for, lol), so I'd just like something that soaks up imperfections but gives that sporty feel when I do manage to find twisty roads. Of course even just a simple refresh will probably make a world of difference given that my current setup is almost at 90k miles.
I am actually on the row m030 springs with the Koni yellows. The yellows allow for dampening adjustments which I have it set to medium and I really like it. Not too firm but just firm enough and I just always back down the dampening to soft. I�m at 95k so it was time.
The Koni Special Active are the way to go in your use-case.
Inside them is Koni's proprietary frequency selective valve that provides exactly what you're looking for: allow the absorption of impacts by expansion joints etc (being high frequency input) whilst maintaining flat cornering and tight general body control (being low frequency input) on the twisties in a broader spectrum than possible without it
The Koni yellows already cope well with this broad spectrum but the special actives do it even better using said valve, a development by koni in the last decade or so.

Stay with the springs you currently have, as increasing their stiffness by going for M030 ones would move you away from a GT-like (as in grand touring, not the race categories GT1 to 4...) suspension.
