Check all the bushes and arms if they haven't been inspected or replaced (I replaced mine with Meyle arms and Powerflex bushes and wow what a difference!!

Now have the AST tops which I installed when I changed the suspension over from the Bilstein/H&R to the AST coilovers.

I'm running Bilstein PSS10 and need to replace the strut mounts on my car as the drivers side has failed.

Suspected cause
Probably a bit harsher in terms of ride, but I have a semi solid 964RS bitsa engine mount kit that will eventually make its way onto my car one day.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.
Check bushes and arms if they haven't been

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.

I'm running Bilstein PSS10 and need to replace the strut mounts on my car as the drivers side has failed. Is there a "better than factory" option?
A quick google search turned these up
https://9lf.de/gb/axles/625-996-turbo-strut-strut-mount-for-bilstein-pss-10-suspension-porsche.html
Everything else looks to be in good order (suspension shop has confirmed), however, what else should I/would you replace whilst the car is in the air?
I just put these on, half-price compared to the OEM ones
https://www.tarett.com/items/996-997-products/996-997-991-suspension/996-997-991-monoballs~bushings/996-986-front-camber-plate-set-996fcplta-detail.htm
My car did a whopping 25m of total distance travelled on a brand New Ohlins R&T coilover kit before I got a don't drive your car recall notice (996 turbo / c4s kits). The recall related to the front coilovers. Ohlins engineered soltuion was to replace the front structs and I was required to ditch the brand new and just installed genuiine 996 top mount parts and bolts washers etc and fit ohlins supplied elephant racing top mounts
I used the Elephant Racing tops until very recently and they were excellent. Now have the AST tops which I installed when I changed the suspension over from the Bilstein/H&R to the AST coilovers.
It depends if you want standard NVH or adjustability and a little more noise.
If you're interested in the strut tops, PM me as the C4S and turbo tops are interchangable
Have sent you a PM, cheers.
Still interested to hear what others suggest to look at whilst the car is on the hoist.
Are there other improvements I can make?
If the car isn't being tracked, OEM is perfectly OK. OEM 996 are almost double the price of OEM 997. They're visually the same - the part numbers are different (just the 996 v 997 prefix tho), and there are guys on Rennlist that have put the 997 mounts in without any dramas. That said, I did put OEM 996 mounts into mine recently.
Check all the bushes and arms if they haven't been inspected or replaced (I replaced mine with Meyle arms and Powerflex bushes and wow what a difference!! Also check the steering arms for play etc
Check swaybar end links/drop links and bushes
Check wheel bearings, brake hoses, pads etc
Remove undertrays and look for leaks (coolant, power steering etc) and perished hoses
Check front radiators for end tank leaks and debris
Check transmission mount bushes as mine were totally cactus. Cantrell street 65A replcements used and she's all good
Check engine mounts, and for the turbo's the oil feed return lines etc
Amazing, my top hats also need changing.
So following any suggestions here with interest.
Was quoted $1500 for supply and fit. So let’s see what comes up.
Just need to make sure you get the Turbo/4CS units as they’re abut different to the regular 996 units due to angling of the front shocks/ front diff setup.
@Joz
it is easy enough to do at home with some jacks & jack-stands. Just book in for an alignment afterwards and you're all good - plus the warm & fuzzy feeling of doing it yourself
🤗
As noted, in a post above, how good is your rubber on your engine and tranny mounts. Recommend 997 tranny mounts.
Probably a bit harsher in terms of ride, but I have a semi solid 964RS bitsa engine mount kit that will eventually make its way onto my car one day. They don't make some parts like they used to from last century.
I thought there was room for improvement on my stock suspension and had a bit of an itch to scratch and came up with the following to scratch that itch (refer to parts list below)
Bolded parts below are possible improvements to consider on your existing setup . All parts that reference links and boots were all sourced from Tarret
The other improvement I made at the same time as refreshing the suspension was to go a bit harder on the yellow theme (ohlins springs are yellow) and I did a bit of a tweak to the braking. i.e UMW brake upgrade kit with 996gt3/gt2 front 6 pot calipers up front and rear 997 calipers with 350mm discs all round to fill out the wheel arch and compliment the reduced 4x4 look

*post note to the above list. Ohlins mandated that I had to rip out the brand new and at the time just installed factory genuine front top mounts and bearing plates and had to use elephant racings front top mount kit which they supplied free of charge as part of their product recall of the front struts . Wasn't too happy with that as I try and stick to genuine factory stamped P car parts as much as possible except were I see a potential improvement over the factory stock parts. Just not in the purists camp of them having to be exactly 996 turbo parts
A shout out to a forum advertiser
@Jocaro who installed the recalled replacement parts from Ohlins and dialed in the above setup. Let's just say its a bit firmer than stock and a noticeable improvement on the 18 year old stock parts. Added bonus was when not behind the wheel, visually the the factory 4x4 look was gone but probably at the expense of more consumable front lips to stock up on going forward
I don't consider it amazing at all. I have posted on here on a few occasions that even on pristine so called top conditioned peaches with low km's and premium asking prices, you need pump in and allow 5k to improve drivability behind the wheel of a 996 turbo approaching 20 years of age. eg tranny mounts, engine mounts and suspension top mounts and bearings along with some form of 997 factory shifter mechanism.(stock, shortshifter or gt3) and some spare non sticky radio replacement buttons and either pirelli zero or ps2 michi's on stock factory rims is where to channel that 5k regardless of what a ppi says if they haven't been replaced at all or have not been done recently. Then a boost leak check is also a must to do item. There is another behind the wheel level to get to that comes with having aged / inferior rubber and plastic bits bits sorted out. Most don't invest in preventative maintenance until the the individual part needs replacing. Get in early do the preventative maintenance up front to get rid of some slop that is really noticeable when you do the above as a collective as it tightens the handling up and driveability from the get go when the cars on your watch and enjoy.
Then a tune and exhaust is a no brainer after that for much more incremental smiles per mile.
This, this in spades!!! Even the non-turbo's like my C4S that is approaching 20yrs needed full suspension refresh (every single piece), engine and gearbox mounts replaced, wheel bearings, brakes overhauled (calipers rebuilt, lines replaced, pads, fluid etc.) before it even felt like it should have...With cars like these approaching 20 yrs of hard and sometimes dubious servicing (usually due to cost) they are going to be projects, but thats the fun in owning them.
Understood, and hence my post. Eg Appears you are surprised that you have to do them (both of you and I am guessing nothing mentioned on the PPIs???? or you guys making up for COVID and the pror owners and driving them like they stolen at every opportunity your behind the wheel. that when the rubber bits tend to show their age)
Well after some searching and frustration the clunking front end could be something less sinister than my top mounts.
The jack and tool set may have been the noisy culprits. So I have removed them temporarily and will will do a thorough sound check during the week. Fingers crossed
🤞
Well how about that
😀
I couldn't think of anyone except my neighbour with a 991.2 and he doesn't share the other hobby.
Great to see another familiar face around these parts.
