I searched around. Found a few threads but nothing conclusive.

Seems on a base 997.2, non pasm getting an active system is not an easy/cheap route.

Of the passive systems r&t and pss9 seem to be the top recommendations. Am I missing anything obvious?

Not looking for anything out of this world but will end up having to refresh suspension on an 13 year old close to 70k mile car eventually. Would be doing the labor myself so thought maybe putting something in better than just replacement shocks and struts would be worthwhile.

I have a 997.1 2005 C2S and should have just installed the TPC DSC Sport Controller since my car is mostly a daily driver and lesser frequent spirited drives.

Instead, I went with the Ohlins R&Ts. Their ride height adjustability was the main feature I was looking for. Their overall adjustability is better than average and attracts those who track their car regularly. They provide a very predictable response in corning situations.

One thing that might be troublesome to some is their potential need for a rebuild/assessment at the 20000 mile mark.

All-in-all, a good purchase though...

Thanks. I did read something about a rebuild, is that strictly 20k miles or a time component? I don't see myself doing another 20k miles any time soon.

Here's link the manual https://www.ohlinsusa.com/files/ohli...N_AUTO_R_T.pdf .

You have a NON PASM trying to add PASM? Yeah thats a bit difficult. You would have to get something by like DSC Sport with their tractive coilovers.

Yeah, but that's like a $9k purchase vs something passive like R&T for $3k or so ... vs just refreshing everything with new shocks/struts for 1500 or so. I was just thinking if I'm going through the effort and doing all 4 corners that I may as well splurge a little.

What's up with the ohlins extension kit/cable for cars with bose? How does that work and is it needed?

jchapura

I bought these. They are installed to allow you to adjust the dampening from inside the car. Here's a pic of the passenger side.

workhurts

Thanks again. Is there a bose amp or something in the way? So without this they're not adjustable without removing a shelf and other component or is there something else in the way?

jchapura

I don't have any pics of this area from when I installed the Ohlins. From what I recall, nothing's in the way, per se, but to adjust the shocks, one would have to remove the shelf.

The adjuster extenders are needed if you wish to avoid having to go through this procedure every time you want to adjust the rear damper settings (15 mins 18 into this video) :

Yup, that's what my car has as well.
I got a C2 with no PASM and has the ohlins installed.

Meraki Autoworks

Oh got it. In that case our best sellers are going to be BC Coilovers and Bilsteins. We do Ohlins every now and then as well.

Can you guys share what compression/rebound settings are you running front and back? How would you compare the ride quality vs. stock?

jchapura

I recently reset my rebound settings as follows - based in part from recommendations from other. I haven't had a chance to drive the car hard to see if they're OK.

• Fronts - 18 out/CCW from full stiff/in/CW
• Rears - 12 out/CCW from full stiff/in/CW

Spring preload adjustment was set up to to get a particular ride height reduction and then to corner balance the car.

When compared to stock, the feel is definitely stiffer across the range of driving conditions.
I don't mind the stiffer/harsher feeling but I can imagine that some would.
They did solve some "bounce" in a higher speed right hand sweeper that had some less smooth areas in the middle.

I went w Ohlins RT on my 2011 non PASM Carerra. I’m very pleased with the suspension set up. Firmer than stock, but not uncomfortable.
