Question About 2012 Gts Handling

[WayneStang]

I just recently bought my 9th mustang, this one is a 2012 GT 6spd.
I'm no stranger to fast vehicles so after having the car for 2 weeks i decided to stretch her leg last night. I was playing around doing 20 rolls in 1st and a couple 2nd gear pulls. Finally I decided to see if it had a governor and layed into it pretty hard. About 130mph the ass end felt squirrely and had me all over the road.
I checked the rear sway bar to see if was loose or needed bushings but it seems fine.
I'm wondering if anyone else has had this problem or knows how to keep it from feeling so loose.

My 2012 Boss -which coincidently is my 9th Mustang also, is stable at high speed. It is lowered, and has BMR LCAs, and Panhard rod.

Was it stable at all before the lowering kit? Ive had a couple 99-04 GTs, a 03 mach 1, pro charged 09 GT that ive topped out (In Mexico of course lol) none bothered me but this 2012 scared the hell out of me hahaha.

I am going to say yes, it's been lowered about 2 years now but there is nothing that stands out in my mind.
