Right! But get this. At a same turn just reversed the car will hold steadyyyyy a much more natural feeling. This jerk is abrupt and unnecessary. Everyone knows their car and how much you can push that limit. I'm no where near this limit turning left.

And I've also rotated my tires to see if it was tire related. Same exact issue.

If you can't kick it off it will be because the engine hasn't fully come up to temp. It's really picky that way.

I sold the OFT and I'm gonna go with ecutek soon. Maybe I can borrow a friends we will see...

But once I try pedal dance mode that should throw out everything electrical.

I did do a quick drift just now through an "S" turn I hear and feel through my steering wheel a loud "Thunk," this happened while I was straightening out the wheel and slowing down.

I've had that thunk since 10k miles. Oh, and as I drive the car harder the steering wheel feels much tighter and actually straightens itself out. (Always a tad to the left) and the jerk is actually a tad harder to replicate but still there.

so something in my suspension tightened up, this happens every time I drive somewhat hard.

make sure in a straight line the steering is showing straight ahead and all four wheel speed sensors show same readings.

then log it uner fault conditions and check out the readings in turns the outer wheel sensors should read higher and make sure steering sensor reading look sane.

it might just be a dodgey wheel sensor, but ususlly the vsc ecu would pick it up and thow a code.

maybe unplug and clean with some spray cleaner the 4 wheel sensor connectors

Lol so I tried the pedal dance mode and wow it makes drifting feel amazing lol. However the lot I was drifting in was behind a church and the guy didn't have many holy words for me lol he told me to get TF out and he will call the cops next time.

I tried to explain to him my situation but he didn't budge lmao.

Anyways, if I drift right it's smooth and I can hold the drift. If I drift left guess what... ding ding ding, my whole tail end flys out lol.

As I'm driving around testing this further the jerk left is still noticeably there.

What are your guy's thoughts?

Purely mechanical. I'll double down on a torn bushing but I'm pulling that out of my ass. Good luck!

I have read the thread and did not notice if you have tried the different modes. is it just interfering in normal? sport? and five second disable. or is there a difference right to left in driving in each of the modes? if driving is different it is a suspension problem picked up by the control system and it is doing its job. if it drives normally in the disabled modes (right and left at limit) then it may be time to look into the control system

Nannies ruled out. Mechanical issue.

blown RF damper. Is there any oil around the strut?

I checked nothing out of the ordinary, tomorrow I'm headed to a local autocross event and I'm sure we will finally figure it out then.
