Left to right under full throttle 2018 zl1
 

Has anyone zl1 felt like it’s floating left to right when flooring at high speeds say 50+?

Yes I've noticed that as well. Not sure what it is

I have not, what tires are you running?

I was wondering if it’s all the air vent and channnels in front of the car. But get up round hundred gets little nerve racking

I’m running 305”s in front and 325 in back. Hancooks in front and mickey Thompson s/s In back

Having mis-matched tread/sidewall mis-matched front-back can contribute to the car walking on some surfaces. Even some matched treads will walk with grooves in the road surface.

I mean I’ve had drag radials on all my Cars and never had this happen

It is most likely the Electronic slip differential, it can cause it to feel this way as it cycles back and forth.

I have felt that on S/S Mickeys on my C7Z, but that car was a bit twitchy even on the runflats. Was it worse when you put the DR's on? The wheel/tire setup on your car looks great by the way :thumbsup:

No it was always kinda squirly and wierd thing is doesn’t do it like 0-60. Only high speed. Maybe I need to turn all the traction stuff off and see if it’s connected to tya

mine does it too. shifts left and right, car makes 680, lowered on BMR springs and oem tires. perfect alignment(checked this multiple times)

Very odd right victory. I was wondering if I need to put the canard planer things from 1le in to have it have some downforce in front

You are not the first to mention this feeling running the Mickey's. I noticed this on their old drag radials but those were 275/50/15 on a different car. Same feeling though. At highway speed it felt like the car was swaying back and forth.

A10 2018 same feeling....
