60, 80, 100K? What is typical? It probably depends on each case but wanted to know generally speaking how long they last.

I have an 07 C4 with 48K miles. I've been thinking of getting Eibach springs but am not sure if I should consider getting shocks as well due to the miles (or even H&R coilovers, but cant' get much info on those). Last thing I want to is to pay for install and have the shocks go bad in another 10K miles!

Car is a daily driver, I like to retain close to stock ride/handling and not stiffen it up too much.

I lowered my base 997 with Eibach springs (one inch only). I have read in magazines that lowering only one inch will not adversely effect any of the suspension components. The parts dept. at my local dealer said that he has not sold any OEM shocks because they last. Hope this helps. BTW, you probably already know that an alignment is needed after lowering.

 

I cannot tell difference in ride with the Eibach lowering springs . They are progressive springs so the ride is OEM.
Caution: lowering just one inch requires you to be careful with dips and driveways!!!

 

I replaced my OEM shocks and springs at around 150K miles on my 2000 Boxster S.

I broke one spring so I thought given the miles on the car I needed to replace two... which quickly escalated in my creative mind to all 4 shocks and springs. My logic is that I was going to keep the car forever (engine blew about 50K later... this was the 2nd engine in this car).

Technically, they were fine but I did learn a few things:

1 - There was no technical reason to replace the shocks or springs i.e., no wear-related issues that I or my indy could discern (other than the broken spring of course)
2 - The new system rode harder, no doubt
3 - Conclusion: the system is very slowly getting softer

So if someone asked my advice on a say 100 or even a 150K miles car about swapping out springs and shocks due to paranoia, I would say, "save your money, don't bother".

I am immensely impressed with the quality of these parts, particularly given that I am 54 and remember replacing shocks was a normal part of auto maintenance when I was younger. Remember the Monroe TV commercial with the bouncy stage coach smoothed out by putting on a set of Monroes? Americans were getting ripped off... the Euro companies were building good stuff and finally drove the Americans to either go out of business or adapt with quality.

Used to be that you would test your shocks by taking both hands on a fender and trying to bounce each 1/4 of the car. If the shocks felt less than stiff or bouncy, it was time for a new set. We were very scientific back in the day.

 

On my BMWs past, OEM Boge shocks would be ready for replacement after 45000-60000 miles. In fact her ear shock mounts usually went before that. The installation of Bilstiens would then be installed and be considered (by me) a long term fix.

My 2006 PASM suspension is now at 76k miles and shows no sign of being worn out. No leaking etc, rides is fine, as is handling.

 

Thanks all. Sounds like it should be safe to add lowering springs at 50K and still get a few more years from the oem shocks.
