    from what i read the sensors ahead of the cats are for contolling the mixture and the set after the cats is to confimr that the cats are working (i.e. no effect on mixture). i guess you would get a cel that the cats are not fuctioning.

    inspired by pongobaz's mod i attempted the installation and added a few more photos. i had to remove the driver's side vent to acces the screws and remove the duct as well. Also, the workshop manual did not specify to remove the 4 screws between the steering wheel on the column switch cover to remove it but they needed to be removed as well.

    +1 on the APR. Some people have put 3.8 x-51 motors in Caymens. Softronic is better IMO Nick_USA, Why do you like Softronic? I am interested in software for my 2004 996 but Softronic will not answer any of technical questions. I would like to know what parameters they change other than throttle response. For example do they do anything with cam timing and cam lift, mixture, etc. Thanks

    thanks again. i think you pointed in the right direction. this weekend i will see if there is excessive resistance on one of the camber camber plates causing the spring to bind while turning.

    wross996tt, thanks for the reply and thread. the rubber washer/bushing is installed, please see the attachment. is there anytihng that should be examined? thanks

    I recently installed PSS9’s and sometimes can hear a noise when entering my driveway at an angle (no noise when going over speed bumps perpendicular). The noise is hard to describe, it is like the spring is binding and suddenly is free although I cannot feel anything. I checked the installation and could not find any loose bolts, etc. I didn’t lower the vehicle too much and am confident that nothing is scraping. Also, the noise is only from one side. Has anyone experienced this and is there a fix? Thank you.

    thanks for the reply wross996tt and dscott. anyone else out there?

    I recently installed PSS9’s on my 996 C2 and while experimenting with the rear dampening settings it seems that even with the most firm setting (no.1) it is not enough. When you push down in the rear the car comes up higher than the resting height and then down again. Unlike the front, push down and it comes to the resting position. On the softer settings (7,8,9) the rear is significantly under-damped. At night you can notice the headlights bobbing up and down. I am looking for some feedback before sending the shocks back to Bilstein. What settings are people using? Thank you.

    I recently had Darin Fister's ModII done on my 2004 996 and like it very much. No unusual vibrations or resonance. Nice sound.
  10. george996
    I experienced something similar after a hard acceleration and after a few more shifts the pedal effort returned to normal. Found some threads that indicated a bad pressure plate and I would tend to agree. I don't think there is anything wrong with your hydraulic system. Low pedal effort means low force pressing against the clutch disc and are observing slipping.
  11. george996
    This is great feedback. I wonder why my 04 is higher. Anybody else with an 04? It would be great to hear from someone who installed H&R and Eibach springs.
  12. george996
    Congratulations. Glad I was able to help.
  13. george996
    perryinva, would you mind checking the color coding on your front springs? There are two markings at the bottom and one at the top. thanks

    I am planning to lower my 2004 996 and while doing research I found some data showing that the 02-04’s are about a half inch higher than the 99 – 01 models. Please see the PCA article “996 Standard and Sport Suspensions Analyzed”. I confirmed this by taking measurements of my 04 and a friend’s 99. Both have stock standard (non-m030) suspension, same O.D. tires, etc. The 04 was 27/26.6in front/rear and the 99 was 26.5/26.23. Next we removed the wheels and took dimensions of the front strut and did not find any differences. The only difference was the markings on the springs. Both were blue and brown on the bottom but the 99 has white on the top and the 04 was blue. Therefore we concluded the difference in height was only due to the springs. Eibach and H&R offer only one p/n for the 996 and advertise lowering by 1.0” and 1.25”, respectively. Since there were no dimensional differences between the 99 and 04 front struts, I assume that the fender heights of the 99-01 and 02-04 models will be the same after installing any of these aftermarket springs. I thought it would be helpful and interesting to get some replies of height data, model year and suspension type. 2004 996 C2 Coupe 6sp Standard Suspension – 27 inch front / 26.6 rear

    I am looking to do a clutch job on my 2000 996 C2 and it seems like kbrandsma knows what he's doing. I have two concerns: - Without a lift, how high of a clearance would you need to do this job on jack stands? - The special 3 square 10 mm bolt. Which one is it? Can you indicate it on the attached picture of the G36 transmission? Thanks, Joost the triple square is no. 4. The jack stands were about 16.25 inches. See attached photo of the jack stand mod.

    Hi George, I have the same car as you with the same clutch problem. Have you decided on DIY? Has anyone posted a step by step process to replace the clutch? I have the same quote as you, $ 2,000 and the labor time was 8 hours. That's all they would share with me. Thanks, Ken Ken, I ended up doing the job myself. I replaced the clutch disc, pressure plate and release bearing. The clutch feels great, light pedal effort and smooth. I did not replace the DMF or rear main seal. The DMF still rattles during shut down but otherwise I am pleased with the clutch operation. If you are planning to use jack stands, like I did, I recommend modifying the jack stands to lock into the holes of the lifting points. I didn’t feel comfortable otherwise. I’ll post some pics to show you what I did. Take a look at this link for some pointers http://www.c-speedracing.com/howto/996rms/rms1.php I also subscribe to Alldata http://www.alldatadiy.com/ where I got all the procedures, specifications, etc. Besides standard hand tools you will need a transmission jack, floor jack to hold the engine, triple square socket driver for (I can give you the size later) for one of the bolts on the bell housing and a clutch alignment tool. PM me if you have any questions. Good luck George

    Does anyone have information for inspecting/evaluating motor mounts other than leaks? Are there any dimensional requirements? I know that Mercedes specifies minimum height for their motor mounts that are in compression. Thank you.

    I am planning to replace my clutch this weekend and forgot to get a clutch centering tool. One of my co-workers is willing to make one if he has the dimensions. Does anyone know the outside diameter of the pilot bearing side of the clutch centering tool? Any help will be appreciated.

    does anyone know what this part is? I found it under my seat. The seats are not power operated. 2004 996
  20. george996
    yes. The dealer will not perform the test based on the rattle sound alone. They say it is normal and even a new DMF might make the same rattle. Like is mentioend, I noticed the same rattle in a handfull of 996's and 997's recently. I am hoping that while replacing the clutch they will replace the DMF if it faulty according the procedure you referenced. I met with 2 reprensentatives from Porsche, not only thle dealer about this.
  21. george996
    I am having a dilemma about replacing the DMF. It rattles when shutting down; otherwise there are no other issues with it as far as I know. If the dealer replaces the clutch they insist on replacing the DMF as well. The car is under warranty so the benefit of having the dealer perform the work is that if the DMF is found defective they will eat that cost. They will not replace it under warranty because of the rattling. I drove 5 similar 996’s recently and 4 rattled just like mine. So I am looking $2,200 for everything or $500 for DIY (w/o DMF).
  22. george996
    Deciding whether to replace my clutch myself or have dealer do it on my 2004 996 C2 and looking for some input. It’s been a long time since I replaced the clutch in my 911SC so I have some idea about what is involved. I am not comfortable about replacing the RMS myself. The Porsche dealer will replace the DMF, clutch disc, pressure plate, throw out bearing and RMS, parts, labor and tax for approx. $2,200. This price discounted for another reason. If I were to do the job myself I would probably omit the DMF and my cost would be about $500. The DMF rattles during shutdown so I am not opposed to replacing it (dealer says this is normal and will not cover it). I would really appreciate some comments. Thank you.
  23. george996
    Can anyone comment on the difference(s) between LUK and SACHS DMF’s for a 996? From their websites it appears that each manufacturer uses a different design. SACHS offers a “planet dual mass flywheel” that incorporates planet gears. Brochures attached. I believe LUK is the OEM supplier. Therefore has anyone used the SACHS type? Comments?
  24. george996
    I recently spent a lot of time and money to resolve the same problem. One of my rims was slightly bent. Had the rim straightened but the problem wasn’t eliminated. From driving my PS2’s for a few thousand on the bent rim they needed to be shaved. Can’t tell where you are located but I took my car to Nate Jones Tire in Signal Hill, CA and he shaved the tired and did an “on car blancing”. Problem resolved.

    I have a 2004 996 w/6spd. I went to the dealer to complain about a rattle noise from the transmission/clutch area when shutting off the engine. It makes a rattle/clanking sound during the last handful of revolutions before the engine completely stops. There is no noise when shutting off the engine with the clutch depressed. I read the bulleting on DMF’s and my symptom is cited as an example. The dealer let me listen to another 2004 and a 2002 and they both made the same noise. Is this normal? Do these cars have bad DMF’s too? What if I tried a new 997, does it have a similar DMF?
