Default Eibach Springs On Older Shocks

Hey guys, I've been wanting to lower my car for a while now and am about to finally bite the bullet. I don't track the car so I am really just lowering it for looks. After doing some research it seems that the eibach springs are my best option as they don't lower it to much and from what I have read the ride seems to still be close to stock.

My car, with original suspension, currently has 37,000 miles on. It is an 08 C2 without PASM and has never been tracked (I am the original owner). Is there any issue putting aftermarket springs on 11 year old shocks with 37,000 miles? I don't want to spend the money and have them go bad 5,000 miles later. If they go bad 15,000 miles later (based on how little the car is driven that would be about 5 years from now) then I don't car. Also, when installing the springs is there any part I should replace for preventative maintenance?

Thanks!

I say go for it. The stock shocks are fine with the Eibach drop springs.

I have been wavering on this myself. It's definitely more efficient to swap out the shocks when you do the springs, but with your low miles, combined with the added expense of PASM, you're talking about almost 2K in shocks when yours probably won't need replacing for a really long time.

In my case, I have 75k miles on the car so it's more of a tough call.

I've done Eibachs on my 997.2 C2 with 101k miles with the oem shocks and it was just fine. I don't track mine other and use it leisurely. I just had an alignment once it was installed.

I highly recommend it, just had Eibach pro Kit installed, and complete alignment, you will not be sorry, virtually no difference in the ride and looks better, and I'm going on 69K miles and it actually feels better than stock even in sport mode.

While you’re in there, I’d replace the strut top-mounts as they’re not that expensive.

IIRC, the Eibach springs are essentially a factory OEM option in Europe, so the relatively mild drop shouldn't hurt healthy shocks too much.

Well I might be a good example for you to watch. I installed a new set of Eibach springs on my 2007 C4S today. It has a pretty nice stance but have not driven it yet. I just dropped off my mufflers at FD Motor sports. They should be done Friday. Then it’s off to alignment shop. My C4S has 47k miles.
Once completed I’ll do an update with photos.

Thanks everyone. Looks like it’s safe to do. Norcalcdd, did you replace any suspension parts when they did the springs?

117K eibach on stock shocks and no banging.

Considering cutting 1" off the bump stops though.

Anyone cut bump stops?

Like yours, mine is a fairly low mileage Porsche. I did not see the need to replace any additional suspension parts.
I’ll share how it turns out.

i am taking my 2005 base in this week for the eibachs pro. Quoted roughly about $1,300 -$1,400 all in at quality P shop in central Jersey. Is this a decent price? Will report in after wards as well

If that includes the springs, labor, and 4 wheel alignment I think that’s fair

I put Eibachs onto my 06 C4S a couple summers and maybe 7000km ago. Mileage at the time would have been about 75,000km. This past summer it started clicking when turning at low speeds. I’ve acquired new front top mounts, plus new bearings too. They should hopefully fix the noises, but I probably won’t get to that job until the spring.

I installed Eibachs at 45k miles on mine. If you search my profile you will find my install guide if you are planning to DIY. LOVE the Eibachs. They provide better handling, better ride quality and the perfect stance.

You do not need to cut the bumps stops but you should replace them when installing. They are $10 a piece. As @wjk_glynn and @Saaboteur said, I would also highly recommend replacing the strut mounts. I think the stiffer spring rate shortens the lifespan of mount. My rears are starting to go so will need to pull the struts off and replace.

Are bump stops only for the front struts? Is there an equivalent for the rear? Same with the mounts, should I be replacing them for all four corners?

Anyone know the part numbers?
