Hard to say since I replaced 5 parts on each of the front suspension set ups (shock, spring, control arms (2), tie rod end).

On my car the stock bushes were showing their age so I replaced every bush with powerflex poly bushes , that really brought it all together .

Coverage and how to read this overview
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 tried balancing the wheels, etc, but nothing solved the problem.
I am installing H&R Street Performance coil overs and Eibach anti-sway bars on a "high mileage" (120,000 mi.) 2002 C2. I don't know for sure how old my current suspension is. Looks original to me but who knows. (pics below) Either way I think it's time for replacement parts and hopefully it's an upgrade. I didn't want to spend PSS10 money (extra $1,000 at least). I will provide feedback for others who may want to go this route. This should accomplish my goals of lowering the car slightly and improving the suspension performance.
I can also provide some feedback on my installer, Yurii, at Polar Porsche (aka Polar Automotive in Cherry Hill NJ). Yurii is also installing a set of 997 full power seats in my 996. I contacted many Porsche shops (both dealer and indys) and no one even considered attempting this swap. The non-compatible electronics were just to daunting. Yurii claims he will get the job done.
I suspect I may need to replace some other steering / suspension components due to age, possibly control arms, ball joints, etc. but it may be interesting to see the effect of the coil overs and sway bars first, then install the other parts.

997 seats going in:
H&R coil overs:
I see salt is definitely prevalent and providing you No Joy in NJ.
Without appearing too selfish, your suspension upgrade is certainly one solid option for me in the future.
Very interested in your results.
Good luck!
I will definitely report back on the H&R coil overs and Eibach bars.
My driver seat was pretty worn out, both the leather and the seat bottom cushion. The 997 seats are basically brand new and just a better seat. I was able to purchase the 997 seats at a good price. I will post pics after the install.
I have decided to replace all of the following parts too: 4 x control arm/ball joints, 4 x lower control arm/wishbone, 4 x drop links, tie rods. So it will take a bit longer to report the results.....stay tuned.
Just installed Eibach springs, wheel spacers, and Koni yellows at 77K miles. Springs and struts from Tire Rack and spacers from ECS Tuning. Original shocks and struts were done. Leaking and essentially barely functioning. Car now looks great and drives much better. Total cost was about $2500 including installation and alignment. Worth every penny - and the suspension was due anyway.
Okay, finally, after being banned for four weeks I can update my suspension upgrade. Here's what I installed new: H&R street performance coilovers, Eibach sway bars front and back, sway bar drop links (4), lower control arms / balljoints (all 4), lower "wishbone" control arms (all 4), a couple of front tie rod ends. And the result...TRANSFORMED. The car is SO MUCH more enjoyable to drive, I had no idea.
I suspect my suspension was original, so I thought it was probably shot. Now I KNOW it was shot. Car handles large and small bumps so much better, especially noticeable over the small bumps that used to be annoying but now are almost unnoticeable. Overall the driving experience has been transformed. Much flatter around corners. Squeaking, groaning, moaning, suspension GONE!
100% worth every penny (with installation and alignment cost almost $4,000)
The brand new 997 seats are pretty great too! WAY more comfortable.
Yep, IHI on July 4th. I posted a pic of a woman in body paint USA flag. Most of the pics on the IHI thread are FAR more revealing than the stylized body paint pic I posted. Anyway, I'm assuming that's why I was banned. I drove this thing (below) on Pocono Raceway. 2.5 mile tricky triangle, banked turns, wow, that was a blast!! Best $500 bucks I ever spent.
The car was a "standard" NASCAR Sprint Cup style car, well used but still a completely professional race car. I think it was 650 HP. Race compound tires, which make a huge difference. The steering was incredibly tight and you barely had to move the steering wheel at all to adjust.
The ONLY limitation of this vehicle (in my hands) was my lack of high speed oval track driving experience and skill. This was the first time I had driven a real race car on a massive track with no limits what so ever. I was going so fast I was scared. I knew I was not experienced enough (at this type of driving) to push my luck beyond the speeds I was approaching. I hit 160 on the straights. There is no speedometer in the car but they calculate your top speed based upon the max RPM reached in high gear which is logged in the car. The faster you go the better the car handles. It was harder to drive the car at low speeds. No power steering, who needs it!
I highly recommend this stock car driving experience to anyone near the Pocono Raceway. Be sure you purchase the right type of driving experience that allows you to drive the ENTIRE track with NO LIMITS. Some outfits rent Pocono Raceway and offer driving experiences that take place on a smaller course with LOTS of tight turns (sucks). Don't buy that crap. You want to drive the Tricky Triangle? Then drive the whole damn thing with no speed limits.
update: just returned from the first spirited drive after the suspension replacement. A slight steering wheel shimmy that I used to experience is gone, thank god. The vibration in the steering wheel wasn't that bad, just a very slight shimmy in the wheel somewhere around 72mph. I tried balancing the wheels, etc, but nothing solved the problem. The suspension replacement solved the problem.
The most annoying part of the shake was it happened right around 72 mph, a fairly common highway speed in an area where the speed limit on most highways is 65mph. So I either had to drive 68 or slower or 76 or faster.
Anyway the point is a worn suspension could be the cause of a steering wheel shake. I'm not suggesting to replace your suspension if your wheel shakes. Once the far less costly solutions are exhausted your suspension may be the culprit.
I think you'll like your H&rs , I have a set of the sp and h& r swaybars , I love them ,
On my car the stock bushes were showing their age so I replaced every bush with powerflex poly bushes , that really brought it all together .
The H&R sp coilovers don't get much coverage on rennlist but the German made build quality and bang for the buck is excellent . The sps have bilstein dampers , the h&r rss coilovers use konis , so it's good gear . I find the ride quality firm but comfortable and not harsh even on Canadian roads . A good balance between street comfort and track capability .
I also like the adjustable ride height .ive got mine most of the way up which is about an inch drop
Nice thread. I'll be following in your footsteps soon with full shock and strut replacement, but still unsure of springs and sways. Probably bite the bullet and get it done, along with new bushes.
Curious about the seats, though. Did you have to use new rails or wiring for the 997 seats? Or did they fit into 996 rails/harnesses?
Physically 997 seats fit easily in 996, the rails are the same. The problem is making the electronics work. If you decide to try and fit 997 seats into a 996 I would highly advise going with manual 997 seats. They will still have an electric seat back, but the rest will be manual and that will reduce the difficulty factor in a major way. The seat wiring connectors are not the same, it's not plug and play. The 997 seats I had were full power. I found an indy tech who knew how to make it work but it's not easy and requires some special knowledge and tools.
Much easier to get those manual 997 seats into the 996.
Not exactly sure what a 'shimmy' is. My 996 is lowered on PSS10's and I think lowering it has induced a bit of bump steer. If you lowered your ride height when you installed your coil overs, aftermarket tie rod ends/bump steer kits may be what you need. Since you just changed a majority of your suspension components I would look at your alignment next to see if there are issues there.
Shimmy = vibration, shaking. Replacing the suspension components solved the problem. Maybe replacing the tie rod ends solved it. Hard to say since I replaced 5 parts on each of the front suspension set ups (shock, spring, control arms (2), tie rod end).
