What is the best approach for lowering p-car; coil overs or just higher tork springs in order to keep the best overall ride flexability. I have 2007 C4S cab, looking to lower it, but am concerned with, losing the PASM system, making it too tight and not being able to switch back and forth with the sport mode and touring mode. I don't want the touring mode to be too rough. Anyone have suggestions, would greatly be appreciated.

 

Keep in mind that the car already from the factory has a coil over setup, when people are talking about coilovers from the aftermarket they are talking about the spring and strut together as a matched unit. The problem with just springs without the matching dampers on a PASM car is that the valving could be off and you may have accelerated wear. If you don't lower the car more than an inch (TechArt-Eibach) you probably won't have any issues with the PASM dampers wearing out. If you go lower than this such as an H&R kit there have been some instances of the PASM units failing.

 

Thank you for the response. Is it possible to lower the car without changing the sport and regular settings on the PASM, other than the making it a tighter ride all around? Thanks again..

I lowered mine with Techart springs . It's less than 1 inch from stock but since mine is a Turbo the front spoiler is low . I use the stock settings and have no problems. I don't track the car though and would get the coil overs if I did.

There's a new "lift" setup (Cargraphic) posted on these forums which looks interesting .

 

I haven't decided as to track it or not, yet. Thanks again..cargraphic, lift set up?

 

1) Here's the post on the "lift" setup .

2) Here's a front photo of how low my Turbo spoiler is in the Techart . You have no idea the effort I place into avoid scraping that painted lip .

 

interesting concept.. sounds abit like the low riders with air bellows lifts that can be used to bounce cars. Nice ride, I can imagine, I have trouble with my stock front end on curbs...that's mainly why I haven't lowered mine yet.

 

Coilovers for sure, if you are at all serious about the driving aspect of the change as opposed to pure looks. I just got a set of PSS-9s and they are fantastic. On all but the roughest pavement there is no discernible difference in ride quality from stock and mine are actually set a little higher than the default which is quite low, particularly in the front (my ride height is on par with a European spec 997 from factory). In terms of handling the car is far more neutral and I can actually induce oversteer on off-power turn-in whereas the stock car would typically just understeer terribly particularly in tight turns unless you gave it the full swedish flick. There are other coilovers a bit more track biased but for a road car I could not rate the Bilsteins higher.

 

where can I get some info on the PSS-9s?

 

I have had Techart Springs and Bilstein CO's in my 997. I would not put springs in my car again, CO's are soooo much better. The ride is nicer, less chance of shock failure, and if you put Bilstein's in you get a lifetime warranty on the parts, as long as you own the car.

You could talk to Mike at AWE, he is a board sponsor and knows a lot about the Bilstein products.

 

Thanks for all the info. Now, what is the difference in the Blitein Damptronis, PSS9s, PSS10s and coilovers. And what does one look for if undecided on tracking the p-car. What I do know is that the suspenssion I have can be improved on, the problem is what to improve it with, also what do the "dog bones" do. Keep this onfo coming, I'm getting a lot if good suggestions, and thanks. This stuff is addictive, looks like I may be headed to the track, maybe..

 

PSS9 9 Position, PSS10 10 Position, Damptronics are controlled by the PASM computer. If you have an S or a non S with PASM then I would get the Damptronics, If you have a non S without it then PSS9's or 10's are your choices. Like I said talk to Mike at AWE he is very knowledgeable about them (They are also having a great sale right now), and can answer questions much better then I can.

Dog Bones allow more allignment adjustments, I don't have any in my car. I have H&R Sway Bars with the Bilstein's and my car was corner balanced. It was lowered to ROW height and I have the ROW aggressive alignment (Porsche Spec) and my car is a great combo between street and track usage. Nice ever tire wear and great handling.

Get the CO's, you will not regret it.

 

Was looking at the site for the damptronic, and noted they offer system for C4 no mention of C4S, which is what I have. any info??

 

I am sure that there is a set for the C4S, if they make them for the C4 I am sure it is the same product as the C4S. email mike@awe-tuning.com he can set you up.

Best mod that you can do IMO

 

I thougth that also, but wasn't sure, thanks, when I'm ready I'll contact AWE, still need some more info on other products for enhanced suspansion and what would work for what I want.
