  1. RJ,

    I think both Orient Express's post and Mike in CA posts cover most of it. I would add the following;

    1. The jack pad Mike suggests is great for non-aerokit cars but will not work on aerokit cars (it is too wide and will crack the flair). There is a smaller one that uses less surface area that works better on aerokit cars (in case you are thinking of adding the side skirts).

    2. I don't think it is a good idea to lift the car by the engine -- too much stress on the engine mounts. Use the jack points or the hardened area just to inside (center of the car) of the jack points.

    3. Buy good jack stands that can carry the weight and have locking pins... it's your car... and your life! ;)

  2. Thanks!

    Changing from a mid-engined car to a rear engine car is a bit different. The Boxster (like the 914 before it) are great handling cars and... because of their great balance very forgiving to drive. Now, your new Carrera is a little tougher since it has a weight bias over the rear wheels. To compensate for the weight bias Porsche has fitted the Carrera with a tire/wheel combination that promotes understeer -- mainly for safety. Tire pressure changes on a Carrera will have a greater affect on how the car handles and feels than it did on the Boxster. I believe that tire pressures need to be dependent on your driving style. So, there is not a tire pressure that works for everyone. The factory says front 36 and rear 44. I found that to not be the optimum pressure for my driving (I drive pretty hard and aggressive). I found the car too loose at those high pressures. After I experimented with lowering the pressures I have settled on 32 front and 36 rear (cold). Again, your pressures may vary but I would try to keep a 4 psi difference between the front-rear to keep the car in balance. I would not go much below these pressures and certainly not below 30.

    I guess the bottom line is try a few different pressures and record you results (an autocross or closed track session is good for this) and then settle on the pressure that you feel most comfortable with (and gives the fastest times!).

  3. Gary,

    See my first post... there is a tolerance code on each spring that is used to define the proper compensation plate. You won't know what that is until you get the springs. Plus -- there is a 50-50 chance that it is the same as what you already have. If not, you will need to get the correct one. Most installation/alignment shops can take care of this for you.

    BTW... who are you buying this from? Gert at Carewal.com has done many of these. I recommend him.

  5. Gary,

    1. There are different suspension parts for almost all model differences (i.e coupe, cab, 4 wheel drive, 6 speed or automatic). To get the right suspension parts I will need to know: model year, body style (coupe or cab), 2 wheel or 4 wheel drive, and 6 speed or Tiptronic. The differences are subtle in most cases but I think you do want the suspension parts Porsche designed and tuned for your car.

    2. Yes, there are spring compensation plates. The spring compensation plate you need is easy to identify because Porsche uses a color code on the spring itself. For example, on the front springs you will find two bands of color (like green - white) together that tell you what spring model version (like RoW M030). There is also a third color band (on a different coil) that tells you the tolerance group the spring is in. This code stipulates the spring compensatotin plate to use. For the front is: White = 3.0 mm compensation plate or Green = 6.5 mm compensation plate. On the rear the color codes are: White = 0.5 mm compensation plate or Green = 4 mm compensation plate.

    FYI... the shocks also have a color code that tells which suspension they belong with. For the front shocks (White dot = standard suspension RoW/USA; and Green dot = sport suspension RoW/USA). For the rear shocks (Brown dot = standard suspension RoW/USA; Grey dot = sport suspension USA; and Green dot = sport suspension RoW).

  6. Note:

    - The following values relate to the empty weight, i.e. full fuel tank, vehicle with spare wheel/collapsible wheel and tools, but without driver and without additional weights.

    - X74 = 30 mm lower. This can be identified by 1 yellow mark on the shock absorber.

    - A caster adjustment is normally not necessary and is therefore not present! If required in a customer service matter, a caster adjuster may be installed (Serv. No. 40 19 23/Installing caster eccentrics).

    - The toe-difference angle value is also influenced by the vehicle height! For this reason the measured result must be evaluated accordingly! No action is necessary in the case of small deviations from the toe-difference angle required value, as long as the value to the right and the left is almost the same.

  7. Joel Reiser just answered this question at the PCA website. (BTW... 986 and 996 use the same coolant). Here is what he had to say about coolant:

    When I was racing a Porsche GT1 some years ago, they said the coolant had to be special, and it came from Audi dealers as the standard coolant they carried. I don't know what the issue was, but that was easy enough, so I never thought about it too hard. This same situation has carried over intact to the the 996 and the 996-based GT3 race cars. The only difference is that Porsche now carries the coolant with their own labelling.

    The most often cited issue was to do with keeping the water pumps happy but I have no details on what the exact issues were.

    The stuff sold by Porsche was made or at least imported by Elf in Warsaw Poland from Elf in Antwerp Belgium. It is 100% organic according to the label, ethylene glycol based, and has been sold for some years under Porsche part #000.043.203.78. More recent product batches (with same part number) now have a Porsche label, and the origin is the same address in Belgium, now from Arteco NV, so either Elf spun off that plant, or it was always just buying from there, and the private labelling agreement with Porsche was changed to drop the Elf brand name from the supply chain.

    This coolant also has the property of being approved by Porsche, a factor not worth overlooking. Should you have a 996 cooling or water pump problem down the road, it would be better to have receipts from a Porsche dealer for their coolant, rather than the prior savings of a few dollars.

  9. The tank is on the right (passenger) side of the car.

    My understanding is you would need to drain the oil from the bottom of each turbo and that it is an 8 mm hex bolt. Sorry, I do not have a picture or diagram. I'm trying to arrange to take pics with a local guy on his TT oil change. BYW... even after draining all three there is still 4 liters of oil in the engine.

  10. IMHO Yes. Here is why I think so...

    The X51 beefs up the engine, oil system and cooling. Here is a short list:

    - new intake manifold with modified cross-section (material: sand cast aluminium );

    - new intake pipe supports adapted to the form of the intake manifold;

    - new exhaust manifolds with larger cross-section and optimized flow behavior;

    - new cylinder heads with optimized, CNC-milled inlet ducts;

    - new camshafts with larger valve stroke on the inlet side and modified inlet and outlet timing;

    - inlet valve springs adapted to the enlarged valve stroke;

    - modified partition box in the oil pan;

    - modified maps for the DME control module.

    - new underside panel in the transmission area;

    - additional radiator in connection with modified front spoiler, except on the 911 Carrera 4S (996).

    or you could always go with the new GT3 where you get the base for the R and RS racer cars... or better yet a cup car ;) wait I guess that is not streetable... darn :rolleyes:
