degofedal Posted April 3, 2010 Share Posted April 3, 2010 (edited) Hi I bought this Eibach kit from MSA (MSA 6305.140) for my 1973 Datsun 240Z a while back. I'm having trouble determining which springs go in the front and which goes in the rear of the car. I'm hoping someone can help me. There are two shorter springs marked: 260968 / 6305.202 and there are two longer springs marked: 245257 / 6305.001 Thanks so much in advance for your help. UPDATE: Answer found: Thanks in particular to lowrider, but also Eibach and MSA.

240zBoy Posted April 3, 2010 Share Posted April 3, 2010 (edited) I believe the progressive ones with the more tightly coiled springs go in the front Edited April 3, 2010 by 240zBoy Quote Link to comment Share on other sites More sharing options...
degofedal Posted April 3, 2010 Author Share Posted April 3, 2010 I believe the progressive ones with the more tightly coiled springs go in the front Hi 240zBoy Thanks for your reply. Are you talking from personal experience or best guess? I really need to be sure what goes where as i will not be installing them myself and don't want to be double charged because i gave my mechanic wrong instructions. Thanks again.

Best regards Jeppe I had this problem when i installed my springs. I installed the longer of the two in the rear...big mistake! i had to do the job twice! The longer 6305.001 goes up front, while the shorter 6305.202 goes in the rear. Quote Link to comment Share on other sites More sharing options...

degofedal Posted April 4, 2010 Author Share Posted April 4, 2010 Your welcome! Dont forget to post pictures of the car after you get the springs on. I sure will Here's some pictures i took last summer for the the insurance agency. As you can see the car sits pretty high. I'm not sure if it's stock suspension or not. Anybody know what type of wheels these are? I haven't seen them on a Z before. Thanks again. Quote Link to comment Share on other sites More sharing options...

The longer 6305.001 goes up front, while the shorter 6305.202 goes in the rear. Yikes so the shorter progressive springs go in the rear?? I just started to install these exact springs with Tokico Hps and just finished the front up with the shorter progressive springs. I compared the longer of the two springs with my front stockers and they were the exact same height I easnt sure what went where either so I called the people at MSA told me the longer ones went in the back and the shorter springs up front!?! This is for a early 74 260Z. Edited April 5, 2010 by SteveZ Quote Link to comment Share on other sites More sharing options...

This is for a early 74 260Z. When i did mine on my early 260, i put the longer ones in the back the first time around. The rear was on the bumpstops, while the front was close to stock maybe a little lower. I changed them around, and problem solved. When i called MSA, the guy stated that the .001 went on the front.

degofedal Posted April 5, 2010 Author Share Posted April 5, 2010 I wrote an email to Eibach USA and MSA with the same question. Hopefully they will respond with the same answer. I will post here when they do. SteveZ - would you mind reporting your results when you have completed installing them? Thanks in advance.

Yikes well Like I said before I just finished the fronts and havent touched the rears yet. I set the front end on the ground and its only sitting 1/4 inch lower than stock so it looks like ill be tearing the front suspension apart again and putting the taller springs in. It just seemed odd to me that the taller springs would go up front and the shorter in the rear. How much did they lower your car after they settled in?

This is how the car looks with the springs backwards... I hate to be the bearer of bad news, but if the front only lowered a 1/4 inch then you have them installed backwards. As odd as it sounds, the length of the spring doesnt determine the spring rate. The progressive portion of the longer springs has less of a spring rate then the shorter of the two. stock springs: correctly installed Eibach: Edited April 5, 2010 by lowrider Quote Link to comment Share on other sites More sharing options...

Yea thats what I figured at least I caught it before I did the rears too. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
T-Bone028 Posted April 5, 2010 Share Posted April 5, 2010 From a support standpoint...you would think that Eibach or MSA would provide some sort of documentation for install...I'm pretty shocked that nothing was marked or basic install directions were included with the order. Honestly, how hard is it to include a sheet of paper with a couple of directions??? Quote Link to comment Share on other sites More sharing options...
degofedal Posted April 5, 2010 Author Share Posted April 5, 2010 Hi Guys Just got a reply from both Jay at MSA and Abel at Eibach to confirm lowriders info. Jay / MSA: The springs are marked with an identifying part number. The part number ending in 1 goes in the front and the part number ending in 2 goes in the rear. Please let me know if there is anything further I can do for you. Abel / Eibach: 260968 / 6305.202: REAR install right side up so part#'s and Logo are facing up so you can read it properly. 245257 / 6305.001: FRONT same as above Strange that they don't include this information in the packaging.

SteveZ Posted April 5, 2010 Share Posted April 5, 2010 Ok the taller springs on mine read: 280757. 6305.001 And the shorter ones read: 279928. 6305. 202 Uggh now I dont even know if I was sent the proper springs in the first place. Quote Link to comment Share on other sites More sharing options...
240zBoy Posted April 6, 2010 Share Posted April 6, 2010 Went and checked my car for you and I have the progressives actually in the rear. It looked right before pulling my motor for the swap which then raised my front end really high haha. It also explained why I was able to compress the springs onto the strut assembly with my weight. Hope I did it right cause that was a PITA!!!! and let me say that twice cause I also put the front struts in the rear cartridge. Screw MSA though for not putting instructions in that dayuuum box. I still love you MSA though Quote Link to comment Share on other sites More sharing options...

Maybe 260z springs are different from 240z. Did you contact MSA about it? Quote Link to comment Share on other sites More sharing options...
SteveZ Posted April 6, 2010 Share Posted April 6, 2010 Yes I did no response yet...... Springs should be the same our boxes both read the same part # the prings inside just read different Im thinking they just may have updated the part #s as everything else looks the same but still waiting for a response from MSA on that Quote Link to comment Share on other sites More sharing options...
Oddmanout84 Posted April 7, 2010 Share Posted April 7, 2010 (edited) Oh. My. God. I've been running the long ones in the back for over a year on my 280.... ._. The original factory springs were longer in back so I figured it was the same relation with the Eibach progressives... Edit: Just checked my springs, but mine are a different part #. Springs ending in 2 are in the back. Still, I remember from installation that they were the longer ones. Perhaps the 280z is different. All I know is that it seemed like the front dropped lower than the back did. Edited April 7, 2010 by Oddmanout84 Quote Link to comment Share on other sites More sharing options...
