Suspension issue
I need help and I’m out of ideas
This is my second front driver tire that is shredded. This tire only seen Autocross 2 times. Before you say it’s the alignment, I checked the alignment and it is good.
Backstory:
Early 2017, I started hearing a knocking sound in front of the car. I Autocross the car many times but it didn’t bother the handling or felt anything weird driving the car. But thesound is there. Minor imperfections of the road will make a sound but in a smooth freeway, I don’t hear it. I replaced the camber plates, inner and outer tire rods, ball joints, wheel bearing, both axles, front control arm bushing and the steering rack bushing. The only thingI have not replaced are the rear front control arm bushing and the steering rack itself. I checked the rear front control arm bushing and it’s still solid, and I don’t feel anything sluggish or any issue with my steering rack.
What do you all think is the problem? This is my second tire that did this.

Looks like just a bit of camber wear to me.

What year is your evo? Or better question would be what do you have for a front diff? Just because your car is clunking doesn't mean its related.
You really aren't running that much camber so personally I dont think that wear is from camber. And your alignment looks fine so I also dont think its toe related. One thought was if youre racing a lot youre spinning the inside front tire due to an open front diff or simply a worn out one.
Joe(MinusPrevious) asked a question in regards to how many miles are on the tires and I too would love to know the answer to that question.

I run -3.5 camber on the fronts and I will get almost even wear from the inside to outside due to the inside wearing from daily driving and the outside wearing from autocross. I autocross at least once a month and doing so gives me even wear across. Having 10k miles on Re-71's and only two autocross events with the camber, I think you def got your money's worth since those wear fast. How many miles are on your passenger tire? For your next set of tires I would recommend getting some R-S4's, they still grip almost as well but it'll wear like iron if you want to keep running the 200tw.

20k out of those tires isnt bad at all epsecially given that you've raced on them too. However, I do agree with you that something isnt quite right here.
My experiences are right in line with this comment. I dd'd my evo for years running -3.5 up front and just like what the person above mentioned what I found was that Id get perfectly even wear assuming I autox'd the car enough. A couple sets had perfectly even wear down to the point where they corded but essentially the whole tire was a slick. However, in 2016 I only raced like 4 events and sure enough my inside tires corded before I was down to the wear bars. But with all of this being said I was running -3.5 degrees. -2 degree is very mild so Im not that confident it can be attributed to camber wear.
I guess its possible your front diff is getting weak and youre getting excessive inside front wheelspin but and then again Im not sure Id expect so much inner wear. Other than that the only thing I can think of is an issue with a bushing but you mentioned you replaced inner & outer tie rods ball joints wheel bearings and some bushings. Personally, Id get the car back up in the air and inspect that area. If youre hearing a clunk something has play and you should be able to replicate that sound.

He just posted on instagram, alignment issue.. I'm guessing previous shop fudged the numbers by tapping the alignment heads..
