Default Lost with all the suspension options!!

Hello All,

I really need some help with the endless suspension options to lower my 997.2 C2 with 68k miles.

The car has standard suspension now and I'd like to lower it to reduce the giant arch gap! I'd also like to make the car a little more compliant for daily driving if that's possible? There's a lot of potholes where I live and they are a bit bone breaking at the moment.

I've looked at the coilover options that seem to vary from £1k upto £3k and I see there are some aftermarket non adjustable options as well but I'm completely lost in what to go for..

I can't imagine I'll ever track the car and I use it nearly every day so I don't need anything for track.

I really appreciate your help getting this right!

Just install eibach springs and call it a day. No need for coilovers.

Thanks for the speedy reply.

I had read people saying it wasn't a good idea to do that with standard shocks when the mileage gets higher.

Would it be worth getting some new shocks as well?

Thanks again!

Eibach springs + spacers.

I think you're good with the shocks as long as they are not leaking.

My 997.2 C2 had similar mileage when I did my suspension upgrade (shocks, springs, sway-bars and drop links).
I love my setup and recommend it to anyone looking for a more planted and aggressive ride. Link below:
https://rennlist.com/forums/997-foru...r-install.html

HOWEVER as you consider the current potholes to be "bone breaking" already...then you should probably not be looking at lowering springs. The ride will absolutely not be less harsh (which sounds like what you are looking for).

The only caveat here is if you have a problem with your current suspension causing some kind of excessive harshness...although unlikely, if it is the case, then your current frame of reference would make it difficult for me to provide a suggestion.

Hope this helps in some way

Much much better handling and I would say more comfy overall.

Did you change the dampers as well?

I see Bilstein have B4, B6 and a sport one to choose from.

My Indy Shop only recommended to replace the strut bearings. Nothing else.

2009 C2S 174K miles

I am a bit of a contrarian here... I never rode in a car with aftermarket suspension that was more compliant. Every single time, I found the ride jarring or I bang my head on the side window as the car lurches back and forth. I don't like this. I live with my car as my daily driver... But I found the stock setup to not be all that great... like Porsche didn't have the time to properly tune it. The ride bangs when it should be a bit smoother... just seems a bit off. Anywho, the DSC module made life fantastic for me. Just what the system needed. Only the module needed, no other items. I then tuned it further with my laptop. BTW, Porsche never fully implemented PASM in our cars in that all four shock are adapted in the same way as DSC's module mods each shock uniquely as needed by a host of inputs.

With regard to lowering... this is taste obviously. And again, I am a total deviant here on these boards.... I don't find the car odd looking. Every car I see lowered looks like someone sat on it. Just me.... and apparently, only me.

Cheapest mod is the DSC module and if you don't like it, you can sell it off for nearly what you paid for it. Total cost to install: $0... and takes about 15 minutes to do, and then undo.

FWIW ... With 142K miles on my 2010 C4S original shocks I don't find your statement contrarian at all. And I'm with you on the slammed look. The DSC does help, although from the time I accepted stewardship of the car at 35K miles I haven't found the PASM to be overwhelming anyway.

Wayne and Bruce, I’m in agreement with you both. I finally stopped using the OEM Bridgestones and went to Pirellis and added the DSC. Fantastic improvement for daily use.

I don't have PASM.

I too think Bridgestone tyres are firmer than others. When I had a Z4 years ago they would tramline all over the place!

Reviving your old thread. What suspension set up did you decide on?
