X50? X74? What does it all mean?

OK...new boy question here but there are so many 'codes' thrown around on here that it could confuse a stupid person. Fitting into the latter category can someone tell me where I can find out what all these things mean?

I don't know of any glossary that'd have those defined, and I'm quite a newbie myself... but... X50 - power package for Turbo 996s X51 - power package for NA 996s X74 - Euro sport suspension for 996s etc. Some of them I know from the forum, some of them you can learn from a site like carnewal.com.

power output to 444 hp. Includes modified turbo chargers, intercoolers, electronic control units and transmission. Note: Also available in conjunction with Tiptronic S.

X74 Ride height lowered by 10 mm. Stiffer springs, shock absorbers and anti-roll bars. Recommended for 18-inch wheels.

Over on the left side under "General" is an option decoder. -Scott

Thanks. I have noticed that I don't always see that option decoder thing - it shows in work (running NT) but not at home (running XP). I just noticed that the web page my dealer had set up for my car had a lot of these things listed. Here are the ones from that page: 741 - Press Finish Y05 - Brake/Shifter Carbon/Aluminum X69 - Carbon Door Sil Model Insignia 692 - Remote CD Changer (6 Disc) 680 - Bose High End Sound Package P74 - Xenon Headlamp Package XMP - Lthr Sun Visors Lighted Mirror XX2 - Footwell Lighting XLF - Sport Exhaust System C02 - U.S. Standard/Emissions M6P - Graphite Grey Floor Mat 982 - Supple Leather Front and Rear 342 - Heated Front Seats 586 - Lumbar Support-Left Seat 513 - Lumbar Support-Right Seat 446 - Wheel Caps with Colored Crest 425 - Rear Window Wiper P11 - Self-Dim Mirrors & Rain Sensor Now a question. I believe the C4S already has a lowered ride and stiffer suspension - does that mean it also has the X74 package as standard?

As delivered the C4S carries the Turbo standard suspension. For the wide body cars, selecting option X73 "Sports Suspension" will lower the car by ~20mm all round. Curiously X73 is not available as a pre-order option in the US....but PCNA can and does supply the parts.

Houlds...Your car is not lowered unless the previous owner did it aftermarket. Due to US vehicle laws, the bumper of all new cars must be a certain height from the ground. In order to accomplish this, Porsche increases the height of the suspension, to just squeak in over the minimum. In order to return the car to the suspension height it was designed to have, you need to get one of the X73/4, or ROW M030 kits. That is why so many people are initially disappointed with the handling, which is kinda floaty and so eventually lower to what it should be. All that said, since you live in NJ, that little extra ride height might save some $$$ in the long run on crappy tri-state roads....

Thanks for the info. If the car is not handling adequately then I am not yet qualified to know this since it seems to handle very well to me. It certainly does not feel �floaty� but instead feels taught and in control. Of course this could just be that I am not used to this level of car and perhaps after a little more time and/or a drive in someone else�s car that might change. That said, I have already scraped the bottom of the front bumper going into someone�s driveway (fortunately I thought that it might be tight so I went slowly) so, as you say, I might need that extra bit of road height around here. Thanks again! Barry

I got the PSS9 to be able to adjust and corner balance. Having the GT3 aero kit, I do need to keep my eye out to keep the front lower lip from touching the ground. This is only on transitions from street to parking, I have never had any problem with roads. Seattle is not know for smooth roads. I will try to send a pic. all that I currently have are greater than 200K.

What is the PSS9?

its a kind of aftermarket suspension (like Ground Control, H&R, etc)...not made by Porsche of course. what is the difference between the X73/4 and RoW M030 suspensions?

PSS9 is an ADJUSTABLE aftermarket, which is especially great if you track the car. You can adjust ride height, camber, etc. X73 and X74 are the same thing, but 73 is for TT/C4S and 74 is for C2/C4 The ROW M030 will drop your car 20MM front and 10MM rear; the X73/4 are 40/30
