I 've had the X74 for about 3-4 years and am very happy...only drive my car on the street....

 

You are missing that the spring and shock is installed as one unit with PSS9s, With X74, they are separate shocks and springs. To the installer, that makes a difference. If you dont believe me call a shop and ask them the difference in install prices. I got mine installed with TWO alignments (one initially and one 30 days after it settled) for about $450. When I got my springs only installed on my Boxster it was that much without an alignment.

 

I thought X74 came as completed kit ready for install, not shocks and springs separate, might be confused though... The PSS9 with full geo will add to install value though, aprox $500 total, but then you get adjustablility and lower stance, worth the money I think. BUT, X74 is factory Porsche upgrade and nice GT stance. Both have very good but different positives... Still confused, either way I know I'll be smiling from ear to ear when I eventually get it fitted...

 

Question guys, I have a stock 2002CS. I have been told that my car sits lower than some others. I have Bilsteins. I have not yet measured the diameter of the sway bars. Are Bilsteins used on the stock C2 suspension, or only on the X74? My ride is not mushy & the setup seems pretty firm, but not unduly harsh. I came from Vettes, the last of which was a C5 with adjustable suspension that could shake your eyeballs loose, so I know harsh.

 

Bilsteins are used in the stock suspension as well...

 

it is possible that you have the factory sport M030 suspension, lower ride height, thicker swaybars, shocks/struts by bilstein.

Bilstein made all factory dampers for the 996.

 

This is incorrect. The x74 kit comes assembled shock and spring. There are no reused parts. I was the installer and can confirm.

Here is a photo of the kit as it comes from Porsche. (Photo courtesy of Carnewall)

 

You are correct, they arrive completely assembled.

 

Thanks guys, going to make the dreaded descision in the next few days. Here's what a very trusted and reputable installer sent me...

"For simplicity the x74 wins out of the box. For onward tuning and bullet-proof performance the pss9 wins. Installation of the x74 is cheaper as there is no ride height or corner weight adjustments to be made.

X74 installation time is about 3 hours plus geometry baseline and adjustments, circa £320.00 all in incl vat. (total time 6.5 hours). Pss9 installation is about 5hours (including swapping top-mounts from old dampers to new), plus ride height settings, corner weight balancing, geometry baseline then adjustments. Cost circa £570.00 incl vat (total time 11hours)."

UCrazyKid, I'm edging toward the darkside for you and probably going the PSS9 route but you're help and reliable answers/posts have been much appreciated. Just thinking about possible suspension mods later on and the X74 stops that. Although in honesty it's only a '99 C4 and will probably trade up before that point. But then I may keep and SC it giving me a low stance 4WD performer... Damn this is hard!

 

Either way, you cant really go wrong.....Just know the PSS9 is pretty much bulletproof. I have about 100,000 miles on mine...yes 100k....

 

Newport, serously?! that's some good miles... I'll let you guys know how I go, thanks.

 

PSS9s seem to be a lot less expensive than X74. the carnewal.com price is 1995 *euros* which is about $3000 US. tirerack has PSS9s for $1900 US. add a corner balance for $155 US and PSS9s still win for price.

 

Why would the PSS9's be cheaper to install?

 

Gert from carnewal is actually doing them for £1200 GB shipped (C4 only) which is just a little more than $1900 plus shipping to UK. It all works out very close when you factor in the install and alignment, like a difference of $100...

 

Uhh....actually, as of today, 1200 GBP = $2365 US dollars. Good for you, bad for us
