Rear end shakes while accelerating from full stop
 

2010 370z sports manual. I bought it in 2011 with only 1500km. One thing I've noticed with the 370z is that when she's still cold, she wiggles and shake her rear end when accelerating from a full stop. If I get the RMPs up in the 2200 range and settle in the clutch it reduces the shake. When she gets all warmed up the shake goes away. But recently I'm noticing this is starting to happen even when she's warmed up. Would anyone have any clue what this is about?

I've googled and searched, and found squat. Poor searching skills maybe. Any thoughts?

I had this happen to my truck one time. Figured out i had a bad tire that was warping when it got cold.

I actually had this same problem with my Camaro. How long have the tires been on the Z?

I replaced the rear tires last summer. I'm not convinced it's a tire issue because high rpm stops the wiggle.
