Nobody can figure out why my front left wheel is always cupping

So basically I have a front left wheel that has been cupping the tires for a while now. I have had seriously 5 or more alignments 3 sets of tires over the course of 2 sets of different sized wheels with the same results. Also an insane amount of wheel balances

I also have tried both stock arms and have installed SPC Camber arms with the same results. I am on Swift Springs with stock shocks.

So this to me sounds like it has to be a shock or strut issue right?

Would it be wise to try to solve this issue with a new set of Koni Yellows? I am a g37x sedan.

Behavior when driving is noticeable at about 60 mph through 70 mph there is a vibration and you can feel it in your hands barely and you can hear it but it is not extreme.

Every shop I take it to I tell them to inspect the parts and they always tell me everything checks out, tried numerous shops.

Sounds like the shock can no longer keep the wheel on the ground. My bet is that new shocks will fix this issue.

Koni only makes shocks for RWD models, they won't fit AWD. The mounting points are different due to the front drive shaft.

I am going to guess my options are limited. So what options do I have? Hoping not to change ride height too much as I really like the way the car is sitting right now with stock shocks and the swift springs.

However if the new shocks have to drop the car a bit more then so be it. Worth getting rid of this annoyance.

I don't see why shocks alone would drop the car.

I'm not familiar with the awd offerings, but I think KYB (OEM equivalent) is about your only choice.

You could always reach out to https://www.truechoicekoniracingservices.com/

and see if they could take RWD Konis, gut them, and put them in the OE bodies

The only manufacturer that I found 100% makes dedicated X struts is Monroe. But considering the cost of install, and cost of parts, adding a bit more and going with BC Racing coilovers will be my solution once my struts finally die.

Well the vibration has gone on too long, time to start throwing money at the front end suspension. Picked up the struts today. Well see if those fix it.

The G doesn't use struts.

Today, most people incorrectly call the front shocks struts as a generic term.

Check the front shocks and also make sure they are properly fastened and torqued. Also check the entire tie rod end.

Here is what the OEM replacements look like, I have them sitting in my garage right now. I am at 70k on stock stuts/shocks so this replacement is needed anyways, just hoping it solves the problem. My Swift springs are already on the car and will be fitted to these,
