cruceno21 Posted January 31, 2021 Share Posted January 31, 2021 (hopefully posting in right spot now). Yes I searched, and most posts are ten plus years old and many products are no longer available. So I have two questions. First quick background - I have a nearly completely stock L28 in my 75. She is a fun summer car, I do autocross her (not worried about being competitive) and like to hit an open track day a few times a year. She is currently on completely stock suspension (minus an MSA front sway bar I put in two years ago). I have owned her for just about ten years and have done no suspension work to her in that time... so she is due. I am looking at the Eibach Progressive Pro Kit spring kit (link: https://www.thezstore.com/page/TZS/PROD/classic20b04/23-4042) and wondering on struts. I only really see two options out there that don't require a ton of fab. The Koni Adjustable from MSA or you can find great deals on the KYB non adjustable shocks (https://www.ebay.com/itm/KYB-4-SHOCKS-fits-NISSAN-DATSUN-260Z-280Z-74-75-76-77-78-361002-361003-280Z/353183501677?epid=1529958043&hash=item523b608d6d:g:LlcAAOSwv8ZfR-a3). Some suggest (include MSA description) is to not do the KYBs on performance springs. But to do the adjustable Konis instead (which are about $600 for the set versus $180 for the KYBs linked above). So not trying to be cheap, but that $400 difference can go toward the urethane kit (looking at this: https://www.thezstore.com/page/TZS/PROD/classic20h01/23-4100AZ) and other little things as part of the install. It already has new sway bar end links from when I did the sway bar. Thoughts? Should I suck it up and do the Konis? IF the KYBs just wear out fast, I can do three sets of those before I spend what I did on the Konis. What else should I do while I have it all apart? Not sure I have the tools needed to attempt the spindle pin replacement but that another area I think I rather spend money than Konis. Thanks for any feedback. Thanks. Over the winter I am finishing my valve seal replacement and adjusted lash, just finished tuning my AFM, and next up is finally removing all the AC parts before I move to suspension next month. So doing my research here before I order parts and get it all apart. Quote Link to comment Share on other sites More sharing options...
madkaw Posted February 1, 2021 Share Posted February 1, 2021 Hey northerner , I went from KYB’s to Koni’s . I went with Koni’s with my ST springs hoping I could soften the ride for around town and be able to adjust up for auto cross . The Koni’s seem to be as stiff as the KYBS - at their lowest setting. Now - that being said - it could be my ST springs . Also, your car is probably heavier and with progressive springs you might be able to have a greater adjustability in ride .

Hey man, I am back with my Z finally... got her back out and running for 2020, now trying to have more fun in 2021. Anyhow, can you still get the ST springs? None of the sites I have checked carry them, only non OEM ones I have found are the Eibachs. Not sure I am a lot heavier, plus I am planning to pull all the AC stuff before this summer so hopefully drop a few more pounds. Quote Link to comment Share on other sites More sharing options...
Spdrcr Posted February 3, 2021 Share Posted February 3, 2021 I am so glad you posted this. I have the same question. When I look through threads most of the stuff isn’t available just like you said. I was also looking at the kyb. I am finishing up my ls swap and am looking for some wide tires and better suspension. Sorry I can’t help with the answer but I’ll tag along for some info.

Spdrcr Posted February 3, 2021 Share Posted February 3, 2021 have you looked at these? https://zcardepot.com/products/coil-spring-set-stock-and-lowered-240z-260z-280z?variant=21384265269361 Quote Link to comment Share on other sites More sharing options...
cruceno21 Posted February 3, 2021 Author Share Posted February 3, 2021 I had not seen those, I rather have a little stiffer, but lower would work. Anyone have feedback on these? Quote Link to comment Share on other sites More sharing options...
