You could install stiffer rear springs or a stiffer shock dampener, but I'm curious why you think this is an issue? My 88 auto has always done this to some extent with no ill effect.--------------

My VG33E-T used to butt squat so hard I felt like I was rocketing to the moon. I loved it. Z butt is legit my favorite thing about the Zs. My S30s and Z31s all had it and it just makes me smile every time.

That makes more sense.... Definitely different shock dampeners that will resist the movement, wheelie bars, stiffer springs. Something like that should help. Weld the rear suspension so it cant compress? (JK!)--------------

your rear subframe bushings are rotted, your rear differential mount is also likely rotted, there's a high chance your transmission mount + support bushings are also rotten.
if they are, when you shift into a gear - even in neutral, you will hear a CLUNK.
Dont waste your time going bushing by bushing - get the full polyurethane kit and equip the entire vehicle. Best investment by far.
replaced those bushingsLast edited by 88sinZ; 06-06-2019, 08:39 PM.

I think this is a common effect on RWD cars when the weight is transferred to the rear of the car on acceleration. I've seen 240Z's with enough power do it too. As others have said, stiffer springs and upgraded bushings may help. After all, the bushings in most of these cars have never been changed.

Unless you do a full coilover setup I don't know that there are other options from Eibach. I have had those on my car since 1990 and they have been great. 1/2" lowering so not huge lowering but overall they are very well made and as you can guess will be the last springs you will ever need to buy.

You can have custom springs made with whatever spring rate you want.
You could also go to a u-pull-it and try to match something up.
Are your springs original? I put a set of AC Delco 45H3105 replacement springs on the back of my 87Z to get rid of the squat. Amazon is showing them and Moog CC263 springs. Check the fitment for your Z. They are like $50-60 a set, sometimes cheaper.
