As the topic stated, is it worth the money to get Eibach to reduce the bounce on the car? It doesn't cost much and it also gives the look. What do you guys think? To Eibach or not to Eibach?

 

here are my thoughts... and why i went full coil-overs...

the problem with the Z is the struts... they are valved too soft

when you put lowering springs on your car, all you are doing is shortening the piston travel of the strut. this means the strut cannot travel its "normal" distance to dampen the suspension movement, as some of this travel has been taken away.

to counteract this, spring makers give stiffer springs than stock. this will basically stop the strut from compressing too far, as the spring is pushing in the opposite direction (and harder now)..

lowering springs do NOT affect on the dampening ability of the suspension (which the strut does). you basically just made a stiffer, shorter oscillation... but it will still oscillate cause the dampening is crap on the stock struts.

the best bet (besides the Nismo S-tune kit, or one of many coil-over kits) is to wait for someone to match a high quality strut to go with the eibach springs...

i now have to replace my bro's rear strut on his 3.5 altima, after he had put on eibachs a couple months back... the strut is blown, and squeeks like crazy. needless to say, the eibachs are going back in the garage until h can find decent struts to match up with them...

I've seen this happen on other cars when Eibachs were put on with the stock shocks/struts, despite Eibach's claim that they were compatible with the stock dampers.

 

What's in the s-tune kit? and How much?

 

If you haven't read the previous thread yet, Nissan is changing the springs for all Zs built before September 19, 2002. If your car was built before that date, the replacement springs are softer than the OE units delivered on the early cars and are supposed to cure the tire wear and bounce problems. Nissan should be issuing a recall soon to replace the OE springs.

There are several threads on this topic and it would be wise to search down those threads before putting up new ones. There is a lot of repetitive info in this and other threads.

The thread is, "Oh, BTW, did I mention that FEATHERING....".

Just a suggestion.

 

Boomer, I checked threads and didn't see anything about Nissan planning a recall, though I did see the info about the spring change for production. Is that speculation at the moment or is there more definitive info indicating that a recall will occur?

 

This is an email I got from Koni.

Howard,

We have done the development on the 350Z and are waiting for the first run to be finished. At this time, we're looking at a late summer release. Thanks for writing.

Gordon

 

How did I missed this thread?! Is this true? can someone confirm this? Thanks.

 

Yeah, here's teh thread.

I'm not going to get to excited about the TSB on the OEM springs just yet. I'll have to see it in writing!.

More to the point, I rode in Marcus' (aka TXSTYLE) car today who he had the Eibach springs put on his car last Friday 3/21. We rode for an extended period, with some very spirited moments of acceleration and manuvering not to mention a steady high rate of speed! Let me just say that the Eibach springs are the answer to the bouncy ride! There is a world of difference in the ride quality of his car and mine (without Eibachs). After riding in his car it's a no brainer... and cheap to! My favorite kind of mod... cheap!

 

So the newer 03 Zs will have a ride more like a Escalade due to the newer softer springs?

 

Boomer,
Interesting find. I'll talk to my dealer ASAP. Thanks for the leg work!

 

Guys,

I emailed Partspeddler and he confirms the spring part number change.
