Ride and suspension questions - ZR-1 Net Registry Forums

HAWAIIZR-1 · 03-10-2011

As some may know, during my rebuild I replaced every suspension bushing with poly. The only other things were the rear bolts to lower the back about 1/4" and new front stock shocks (I have new rear shocks, but did not have time to replace).

So after I finally got the Z running and before shipping I put about 200 miles on it. It rode really bumpy and was bouncing all over the place in my opinion. I know I have not driven it for a long time, but it definitely felt like something is not right. I understand that polys will not give like rubber bushing, but did not think it would bounce around like it does and seems more like shocks or binding of suspension parts.

When jacking up under control arms, etc. it seems to move freely.

Any ideas of what to check once I meet up with the Z again?

If anyone has done a total replacement of bushings and can share their input about their experience it would be great? I think it was Rich that might have done a replacement like this with stock shocks.

I wish I could describe it better, but other than saying that even on the freeway it felt like it was bouncing at the slightest dips and bumps. I could not see it, but if you can imagine it following a car that is bouncing like the idiots that cut springs to lower their cars. My Z is stock height other than the very slight lowering of the rear, but still keeping the front lower. It was aligned after the replacement of all the parts.

Thanks!

Craig
