Angry Car feels unstable while turning....

I got new rear tires the other day and after that i noticed when i turn into a corner above 45mph or so it feels like the back slings itself in. I also get abs feedback through the brake pedal... and also if i am moving in a straight line and turn the wheel back and forth rapidly the back end feels like its floating and sways. I checked all swaybar endlinks and other suspension parts and i cant find anything out of the ordinary, any advice on where to start or anyone else ever have this problem?

check the trailing arm bushings or anything related to it... i had the same issue and it always caused weird handling during cornering.

good luck!

Could the bushings make it feel that unstable though?

What I cant understand is why the ads kicks in...

^yea. once the bushing's gone, the arm tends to slide back and forth to about 1 inch from it's original position.

just went down to the garage and checked the arms, they are all tight, theres no play in anything, and all the bushings look great. No cracking or dry rotting or anything like that...

Now im really stumped..

Believe toyo proxes fz4 is a all-season tire. Your expectations are too high.

i went from nitto 555 extremes... is there really that big of a difference?

It feels like the rear end moves 5-6 inches side to side...

No. With respect Nitto is also a mediocre tire.

Before buying tires check these test results: https://my350z.com/forum/showthread....ighlight=tires
