How do I know when stock dampers need replacing?

Got about 45k total miles and 60 track days on 2008 OEM suspension, pushed pretty hard but still performs well. Just though I noticed on the street today a little more bouncy ride than usual in Normal EDC mode, like its under-damped or something. It may just be my imagination but got me thinking about how you can tell when its time to replace/rebuild shocks, oem or aftermarket, like what are the symptoms, etc. Thanks.

Tell tale sign that dampers need replacing is you will notice oil leaking or weaping from around the damper.

That said springs do the lion share of controlling the suspension movement that damper just fine tune the movement.

With that many track days may be time to swap the springs/dampers altogther.

Dampers don't need to be weeping or leaking to be classed as worn, although, it would certainly be safe enough to continue using your current dampers as they still provide sufficient control for everyday driving.

If you want your vehicle to perform like it should, I would definitely change your dampers. I changed all my dampers and its associated components after 48k miles and 1500 track miles, as I lost a significant amount of low speed rebound, especially in the rear. I do a lot of rally-like driving as well with jumps, so the suspension takes quite a beating.

Its a really simple test. Just go over a speed bump and if your car does this...



...your shocks are bad. If shady characters start to surround your car...roll up your windows.

Your welcome.

Seriously, put some weight on one corner, the car should return to normal height and not bounce at all. But at 50k miles you can be pretty confident that your shocks are worn although they may not be shot or dead.

I was in the same situation a few months ago. 55K here. The rear end would feel it needed more rebound and would get light at mid/fast sweepers. I took a leap of faith and got EDC Bilsteins with Eibach springs. Truth be told, per data I am a little bit quicker and the car feels liveable on DC streets. I will be at Road ATL next month with Peachtree, welcome to take it out for a spin, check for yourself and compare to yours. That should be a good yardstick for comparison.

My shocks, while I cannot say were worn down completely but new shocks really woke the car up.

Thanks. That's pretty much what i figured. Mine are probably worn but not shot. When they need replacing I"ll prob upgrade to some JRZs or such. But then again, not sure how long I will keep the car. hate to mod up a car that's on its way out the door. save the few bucks for my P-car...

Lutfy, I'll definitely see you at RA in Sept.

I was in the same situation. The Bilstein EDC with Eibach and H&R bar (already had plates to -2.5 camber) really transformed the car. Am in love with it all over again. Feel free to take it out for a spin at RA and you'll know I was in the same boat as you about this car out the door, but now be keeping it for 2 years at least. Very satisfying.

Whats your P car? I have a stock 997S which is kinda like the M3. Needs camber/shocks etc. Keep the M3 if you have money/mods tied to it. On the track, my M3 is faster and more satisfying for some strange reason.

I'd just buy some low mileage EDC dampers.

I've been lusting for a mid-engine platform like the new Cayman S. almost pulled the trigger on a 2012 C-R but decided to wait. figured I'd miss the HP of the M3. ...will probably continue to wait and keep flogging ole Betsy here. She's still a hellavalotta fun.
