I want those shock bearings too many other parts to buy

 

Those are badass.

 

Indeed, I'm going to finally buy the rear upright bushings I've wanted for the last 2 years.

 

I can't say enough good things about these bearings. I had them on the S13 and every possible benefit was realized. Improved squat from less bind, eliminated sketchy feeling from the rear from bushing deflection, no noticeable increase in NVH even in a quiet car. I had Nismo bushings in the uprights before this, so I can only imagine that the improvement will be even more dramatic in a car with standard bushings.

 

 

That means buy some now, though SPL sells the Z32 shock bushings for 150$

 

I thought all the ones SPL has are for the arm locations and not the shock mount ?

 

SPL has had Z32 RSSB for a long time, they've had 2 or 3 different versions. Look in the Z32 section under rear multilink and you'll find them.

 

No, I'm not just stroking off Def and the NRR community at large. Go see how much bind a stock setup has. I tried to do that bumpsteer plot with all the bolts tight. I couldn't get repeatable numbers because it was deflecting the subframe bushings and teetering the car, despite the fact that it was on jackstands. That was with the coil off and sway disconnected. Reducing the bind in the rear makes an easily felt change in the rear suspension.

Edit: screw "easily felt". It's more like unavoidably noticeable.
