BTW - I ran K-Sport on a Liberty GT which were great - no issues for 2 years+.

Had the filter apart and tested the pump from an external power source and it appeared fine.

I'd prefer coilovers where I can adjust the right height.

You can adjust the settings from soft to hard on the dial I ran mine a tad over the middle setting.

PS Just a view but I would not just put coilovers on the a car without sorting out adjustability in terms of both toe and camber when it comes to a wheel alignment unless you have a fat wallet and like changing tyres out that wear prematurely.

Hi all,
Im just after some recomendations for upgrading the suspention on my 996. The car still has original shocks and springs and would like to buy new shocks and springs.
any suggestions as to what brand ? where to buy from?
Im looking for somthing thats more performance and wouldnt mind if they are adjustable.
Do Ohllins make suspention for these cars? i have Ohllins on a lot of my bikes and they are really good.
Im off to the USA in a couple weeks and might get some when im over there
Thanks for any help
Dan
Ohlins are awesome but not sure if they do porsche. KW or bilstein coilovers are the most popular. I run kW on my cars (not the porsche yet) and love them.
I have Gemballa coilovers fitted to mine which are excellent.
The Gemballa coilovers are manufactured by H&R and branded as Gemballa so I suspect getting the ones with H&R stickers will cost less.
Ohlins make a 996 Carrera set:

Thanks guys , in the mean time i also found a set at pelican parts. $3200 for Ohllins, think i will go with those. Cheap really, The rear shock on one of my ducaties is worth that much just for 1 !
they work great on my bike also.
Have you blokes upgraded? I bet it makes a huge difference to the way the car drives
I had the Bilstein PSS-9s on the 996 and set it to GT3 height - it drove like it was on rails, stiffened it up but I loved the ride. You can adjust the settings from soft to hard on the dial I ran mine a tad over the middle setting. For me its the best upgrade over the standard suspension I did to the car.

I organised a group buy from carnewal on rennlist at the time I got mine they were brilliant to deal with.
Brands like bilstein & KW. Ask this guy for a quote!! He's easy to deal with.
http://www.streettotrack.com/
I bought my turbos, housings ect from him. I couldn't find a better price than he gave me. This was the GTX turbo i got, Got it cheaper and quicker than anyone in Australia could get me. He just quoted me $2900 delivered for KW v3. $400 cheaper than anyone else.
Dan,
what did you end of going with for these?
I'm in the market myself for an upgrade. I spoke to BIlstein who suggested I should upgrade the shocks to B6's and use the existing springs.
Anyone got thoughts on that?? I'd prefer coilovers where I can adjust the right height.
thanks
Tim
Subscribed. I just put my money down on my first 911 - an early 996 Cabriolet. Manual of course.
It's got stock suspension on it, but I've always had aftermarket suspension in my "fun" car. I've been reading up on suspension upgrades for the 996 and am interested to hear what you guys end up doing.
Cheers
Guys If you haven't read it this thread may also help as whilst its called exhaust tips it ventured into suspension upgrades as well
http://porscheforum.com.au/topic/9008-exhaust-tips-for-996-ideas/
I went KW V3's and dropped the car by 20mm. Running stock settings on them which work well for me. Car feels a lot more direct in steering, almost go-kart like. Ride is definitely firmer but not too firm, can be crashy at first when they're still bedding in across tram lines if you don't hit them at an angle. Corners extremely flat now and doesn't pitch forward or aft under heavy acceleration or braking.
Plus with the V3's, they're coilovers which means if you're like me and have a driveway which you could scrape on, you have the choice to easily raise the car.
what about these :

im not cheap but im just curious.
Knowing me, I'd probably buy em and give em a shot .. but ..... at that price all show no go maybe?
Coilovers are made with/from
•
SAE9254 steels springs
•
Aluminum upper mounts
•
Japanese NOK oil seal
•
Japanese FBJ bearing
•
Italian IP rotary oil
.... and made in CHINA with famous Chinese "PlastiSteel" and quality ... call me a cynic ....
I looked at every suspension set up in the universe I think and those came up in every search I did every day for coil-overs...!!
These also caught my eye...
http://ceikaperformance.com/Custom_Built_Coilovers/PORSCHE/996_c624/
In the end I couldn't put them on a Porsche. Not from snobbery I just couldn't find enough info about them to get an idea of quality.
BTW - I ran K-Sport on a Liberty GT which were great - no issues for 2 years+.
H&R went on the 996 yesterday.
Renamed the thread to make it easier to find...
Jim.
It took me 9 months, and wanted something different from the standard d PSS10'S / KW's but I finally got a set of ohlins R&T coilovers for my 996tt that were not sourced from the US where they are big bucks relatively speaking. First local order took 4 months before they said factory is no longer doing runs for a 996 turbo (refer to prospeed in the link below ), then ended up getting a set 4 months later from the UK (design911 on a 20% discount sale that took 3.5months after they confirmed they had them on two week backorder from the factory when I ordered them). I had ordered some tarret end links specifically to work with Ohlins coilovers hence was sort of locked in / was patient.
Note
best price I found for Ohlins R&T landed to your door if they can get them after heaps of searching on the web globally is actually from a nsw central coast shop, prospeeed racing

PS Just a view but I would not just put coilovers on the a car without sorting out adjustability in terms of both toe and camber when it comes to a wheel alignment unless you have a fat wallet and like changing tyres out that wear prematurely. eg rear adjustable toe links, front shock top mounts and bearing plates (both generally wear badly) as a minimum (I went with 996 GT3 adjustable lower control arms with a guess on required shiming gt3 rear sway bar and tarret sway bar end links and adjustable toe links to compliment the ohlins R&T coilovers). Everything is still in boxes , works well on paper based on my research, but can't comment on the setup / fitment as of yet. If one has not sorted out your engine and tranny mounts recently, I would recommend getting them sorted whilst doing your suspension. (eg 964 RS semi solid engine mounts and 997 tranny mounts) eg may as well stiffen up the ride both in terms of suspension and drivetrain movement at the same time.

I've since put me v1s.on, with monoball top mounts and camber plates. Have ERP spring plates at the rear, so everything is adjustable now.
Ohlins are now making more suspension options for our cars since that post in 2014...
I went with KW V3 on my 997 they feel great. Lots of adjustment. My rears let go of their oil 3 weeks ago within a week a replacement set arrived from OS and KW paid for the fitting. So there back up service is pretty good as well.
Hi Tim - Been on for roughly 2 months so far and no issues.I did several upgrades so can't just put it down to just the coil overs but I do prefer the ride now.
This is what I had done:
Coil overs / Solid sub frame bushes (these will drop the car .25inch on their own) / Tarett front strut tops / OEM front bearing plates / Tarett adjustable rear toe arms
Had the car aligned at Heasman Steering in Sydney and the technician said the car drove really well. The adjustable toe arms helped. He also mentioned I could go + / - 10mm without a realignment as well. Running slight negative camber in front and about -1.20 in the rear.
Looking back the factory setup was tired and this had made the car feel a lot more planted and eliminated the light nose feel at speed and it look better as well. Way to high from factory. I'm not GT3 low but low enough. Roughly 1.25inches lower all round at a guess!
Car drives like its on rails and the coil overs are not noisy at all.There are other suspension options but I decided I would rely on the H&R
preset damping for these "street" coil-overs which made them better value than some other preferred brands. These also have more height adjustment from what I've read. Money was put to use else where.
That was after AOS was done.......then the crank sensor went kaput.....replacing that has made a world of difference to the car...
Jim.
Since I bought the car it had always taken several slowish turn overs to get the car started. I had always intended to replace battery, which appeared to be fine as I thought it may help. I ended up replacing it at the same time as the suspension updates. I had noticed previously that the car appeared to be losing power - I actually though I was getting used to it after a year of driving. A few days after all the mods and new battery etc the car started taking longer to start and was flat spotting on acceleration at random places in the rev range - different gears etc. I had no codes thrown though. Went back to mechanic and he took it for a drive and basically said the car was in trouble! Initially he thought it was the fuel pump on its way out or blocked filter. Reason for fuel avenue was that when we did the suspension he needed me to fill the car and he is next to a budget place. He thought maybe fuel contamination was the cause. Had the filter apart and tested the pump from an external power source and it appeared fine. At that point he plugged the car in and it had a code stored in memory but no CEL.
Sensor may have been intermittent and correcting itself before code was thrown? Was like night and day after sensor went in. Car fires up quickly every morning 2 - 3 turns. I'm not blowing any smoke now on start up, I did switch to Mobil 1 0w-40 as well when serviced. Idle hunt has decreased dramatically and idle is almost stable and lower than before. Oh and new breather hose!
Jim.
Thanks Jim.
Looking a Pss10 which are on sale now at
Carnewal. Can get them delivered here for $2930 AUD, which I thought was pretty good?! Just trying to work out what else I need. Bushes? Don't know enough about suspension, steering, etc.
thanks
There are very few bushes that aren't independent of the coil overs.
The only parts you can't get to post a coil over install is the top hats.
Although there are a few parts that require a realignment if changed such as the "coffin arms".
Mate I'm not an expert but had some good advice from this forum which was backed by what I'd read elsewhere.
smit1200 gets a mention..
Purchased along with coilovers:
After market strut tops (stock strut tops will do).
OEM front bearing plates.
Adjustable rear toe arm - Without them you will not be able to get the toe set correctly if you lower past a certain point.
Jim.
Ok, the plan was to upgrade the suspension with an option to lower it, probably 20-25mm.
So any advice would be appreciated on what other components I need if buying the Pss10 Bilstien's. The steering isn't necessarily loose, but definitely not tight light a new car. Should I be also looking at replacing bushes in the steering components?
thanks for any help you can provide
Tim
Yeah, I saw that which is what got me thinking in the first place. He replaced everything though.........which looked like it was pretty labour intensive
