Message If you still have these upper arms on your Z you might want to check them for bushing deterioration. I would call it a complete failure, as they were becoming dangerous to drive with. And these were the replacement arms they sent me after they found cracks in the original narrow design I had on the car. I installed then at 107K miles and removed them at 150K miles. Had them on the car for about 6 years.

I think I started noticing my car Handling different earlier in the year. But at the time it changed I had installed a set of Powertrix coilovers, so I thought it must just be the way the new coilovers feel. But there is an "s" curve on the way to work and when I would go around it I would feel a shift in the front end when I would transition from side to side. Then I heard some noise when I went over a speed bump. When I got home I looked with a flash light and saw some strange things about the arms.Like they were offset to one side, I thought it was only on the drivers side but it was even worse on the passenger side.

I just happened to have a set of Powertrix upper arms I had not used yet so I installed them. Wow what a world of difference, car handles great now.
