997.2 Suspension Refresh - what to do?
Discussion
My 997.2 C4 S is on 52000 miles and I’m keen to do a suspension refresh So it is as good as or perhaps better than new. It’s had top mounts done recently but am keen to do all necessary bushes etc and possibly shocks and springs. I don’t want a track set up so am wondering if OEM is best way to go...? Keen to keep PASM. Is there a definitive list of what I should replace anywhere? And engine mounts - best options? Any thoughts and experiences much appreciated.
My wife's 997.1 C4S went to Chris Franklin (CoG) at 11 years old and 56k and ended up having everything except springs.
Dampers were still good but he had to cut top mounts off and while I was tempted to send them away to Bilstein to be rebuilt we bit the bullet and replace the lot while in there. Transformed the car (which has become very noisy over bumps and thumps). If you want that new car feel and don't want to have to do more work in another 10k, do the lot while stripped down.

On my 997.1 I've just had 4x shocks replaced with Bilstein B4 (Damptronic) OEMs.
It made a difference but not that much TBH. Definitely will want to be doing all the various bushes next. I hadn't initially as some had been changed piecemeal over the years, but am now wondering whether it makes more sense to do all at once.
Engine mounts I would keep an eye out on the exhaust tip to bumper sag to have a slight indication on how they're doing. Mine still factory at 80k miles but will do them next.

Put a set of B4's on our 997.1 at about 82k miles. Made a huge difference. The rear shocks were well past their sell-by date. Replaced the engine mounts as well (o.e.) just as a precaution because they'd never been changed.It made a difference but not that much TBH.

One is NOT allowed to use the word "refresh" it upsets GT owners !
It’s ‘refresh’ combined with £10,000 that used to upset us. Now that I have a 993 in my life rather than a 997 GT3 I realise that £10k doesn’t go very far. the only people it upset were sellers of cars which have had no work after 15 years ;-p
The top hats tend to go first and you've already handled those. The remaining rubber bits tend to be the next to go, but it's just a matter of how far you want to go. 50k miles isn't that many in the grand scheme of modern cars so the return on your investment for mechanical bits might be fairly low. With PASM you might want to consider a more avanced controller. Not that your PASM controller has worn out, but the improvement in daily driving and sport orient driving were impressive in my Cayman with PASM. https://www.tpcracing.com/product/dsc-sport-v3-con...
Speaking with Speedgelb, I'm in a similar boat and I've put my thoughts into two buckets.
This is my own logic, but an interesting way to look at it.
Round 1, to sort the creaks: coffin arms, tuning forks, maybe strut top mounts (if required), drop links and ARB bushes. Basically, as the poster above yon say, "the rubber bits". Geometry at this point too. Maybe motor mounts if required.
Round 2, if required: springs & dampers.
Can mix and mingle with adjustable ARBs, coffin arms, etc if required, and fit trick springs & dampers if you fancy that too.

How much are we talking about for a complete suspension refresh on a 997 or 987 - standard version, passive set up? Any ballpark figure would be appreciated please.
My 987 has done 61k and also all original suspension could components AFAIK, whereas my BMW 330Ci had numerous suspension components replaced by that mileage.
