Nice to be dialed in out of the box, personally, I hate adjusting things at the track, outside of tire pressure. Flame away...........................

newport......one reason and one reason only. There is no need for PAG to make a specific suspension for each track or one that is adjustible b/c you will NEVER be able to push the car to its limits in a manner that would be comensurate with a suspension system that you desire. 99% of us will never be at the level the cup car drivers are at and therefore do not need the ability to adjust in the manner they do from track to track. And most of that 1% that will (or is coming close) are on the track ALOT. Just cruise over to the GT3/GT2 board and you will find the answer to your question.

I would not go so far as to say that the stock suspension, seats etc su*k and would highly disagree with that, a Chevy Cobalt would meet that. However that being said I WANT THE PSS9!

FWIW
I have had 3 different suspensions on my '03TT - Stock US, X73, and finally PSS9. My experience with these three has not been inexpensive, so I hope that you can learn from my experience. The X73's are well matched springs and shocks that bring your car to the proper look (height and rake). The downside that I discovered 10 minutes after leaving the shop for my first drive is that they were FARRRRRRRR to stiff for the roads, streets, and highways were I live in central Illinois. As I've gotten older, I probably am not willing to put up with such a harsh ride. It got so bad, that I caught myself bracing for the shock as I approached cracks, tar stripes, even shadows cast by telephone poles on the street. After two weeks, I reinstalled my OEM suspension.
Next up was PSS9's. The installation instructions from Bilstein leave a lot be desired. My shop misunderstood which OEM parts to reuse and which to discard. They left out the front upper strut thrust washer. As a result, the front springs would load up and release during slow turning maneuvers, creating a boing sound. I found a more competent shop to correct the problem and properly corner balance and set ride height. the height is roughly the same as the X73. The car now looks ride, handles right, and I have adjusted the damping differently for street driving and DE events. I am quite pleased, but this experience came at a significant cost as I climbed the learning curve.
If you live in a world of billiard table smooth streets and roads, go with the X73. It's plug and play. Otherwise PSS9 is the better choice.
Cheers,

USS TT, I've yet to hear of anyone with a "narrowbody" 996 complain about PSS9s once they're dialed in for customer correctly. They seem to be a perfect match for the street and "some" tracking. For the C4S and TT (widebody 996s) some folks have lowered them too much and end up riding on the bumpstops whichs makes for unpredicatable handling obviously. For the X73/74 I honestly find it decent on the narrowbody but underdamped for the heavier wide body cars. Almost like they barely changed the spring rates to compensate for the added weight

The PSS9's obviously work well as many folks are quite happy with them, but it's kinda funny that one of their benefits as described by many is the ability to "dial down" (reduce) the damping while driving on the street. So I guess that makes them roughly equivalent to using H&R sport springs with the stock dampers (oversprung/underdamped) which is generally derided on this forum. Pretty funny.

>>>>Not at all...If you use H&R springs with stock shocks you are also shortening your shock travel. The PSS9 shocks are designed for the shortened springs. Your stock shocks are not. That is a big issue. <<<<
Good point, as a H&R car sits, it's probably really close to touching the foam bump stops if not already touching.
