front lower control arm

I can verify that 87 & 88 differences are negligible, there are minor stamping variations but nothing that would make a visible difference… I don't have any zenki arms anymore

If nobody post up I'll try to help you out…I have a set of both flavors somewhere.

Well according to:

http://www.z31.com/mods/suspension/

the 87-89 ones are 10mm longer which gives 0.4 degrees of camber.

I'll let you know for sure some time the next month. I've got a set of 87-89 ones down in the shop 2 hours away that I've been saving for my brake upgrade.

Thanks for helping out guys! My issue must be something else because those two control arms are too close to make any noticeable difference. My front camber is way off and since theres no way to adjust this I'm guessing at this point something must be bent.

84-86 are the same length. 87-89 are the same, and 10mm longer than the 84-86. All of the extra length is between the tension rod mount and the ball joint. From tension rod to bushing is the same for all of them. I don't know what the difference is, but the strut tubes are also designed to go with their own style of LCA. Putting 84-86 tubes on 87-89 LCAs will cause negative camber. 87-89 tubes on 84-86 LCAs will cause positive camber (sounds like your issue). This is mentioned about 2/3 down this post. http://z31performance.com/forum/z31-…210#post348210

I don't know if you noticed, but G-E said those are 87-88 arms, so they would be the same length.

Hmmm. I didn't know that before! Interesting. I read that doing this adds track width (because of the 87-89 spindle), but didn't realize it had anything to do with camber.

Just to keep it simple, I just swapped all of it over to 88T suspension parts rather than have to worry about mixing and matching parts.

Jaqattack02, my friend, That's the info I was looking for. I'm going to start tearing down my front suspension and start verifying part #. I believe the previous owner switched a few things with the front suspension without having this information.

Back to the OP wanting a side by side of the 84-86 arms next to the 87-89 arms.
