OP one more time I'm asking you - do you have same worn pattern on your other front tire?

Learn to read yourself. The alignment sheet shows the 2.5* camber. Yes, tires can indeed exhibit symmetrical wear without it being a function of camber, it's a toe issue as that's what drags the tire along wearing it, camber doesn't. You have no earthly idea what you're talking about, and all of us know it.

I suspect issues with caster, either from mis-adjustment or failing suspension components. If this is adjustable on your plates go with less positive caster as more positive caster will pull toe when wheels are turning.

I took pictures with the hood open during my lunch. Is this what you're looking for? or do i need to disassemble something? it doesn't look like you can see much from the top, although it does like the bolts were repositioned somewhere along the line. I will post these pics in a separate post below so i do not clutter this post.

i did some hard stops during lunch and it did not pull to one side or another. the steering wheel did quickly shift right and left but only during very hard braking where the tires screeched a little and/or either abs would kick in (or come very close). i have noticed this quick jolt in the steering in the past but it barely ever happens. i guess dont do super hard stops often either. i can do more testing after work

um i can't say i've noticed increased steering wheel effort. it has always been heavy

so would your suggestion be to go back and try to get another alignment and adjust the caster?

Let me know if you'd like for me to take different pictures

P.S. OP just to take obvious stuff out of suspicion - tires are NOT rubbing on the strut right?

I'm pretty positive they are not rubbing. i can take the wheels off to inspect more but my set up has not changed in years so i doubt it

Look to me that he has negative caster and I'm not sure if plates are correctly installed. They have markings FL and FR. OP can you confirm this?

[anjuna]

nobody has asked yet.... what's your pressure??

[feuer]

I edit one of your photos to will help determine what you have. I think you have negative caster. From my understanding positive caster pulls in the toe and negative pushes out. Try to get it to center OEM-like (the strut shaft to be pointing straight in the middle of the strut bar)and re-adjust camber and toe afterwards.

I took pictures of the driverside first and that one says FL so i guess they're correct

i ran 34/38 for a while and recently went to 32/36. not sure which is better for my set up?

Ok, get the shaft either to OEM-like position (in the middle, center) or from that centar like pushed to the back (towards windshield) That should help assuming suspension components are in OK condition.

The Vorshlags can only go from stock to more positive if installed correctly, fwiw.

So you are reiterating my words basically eh?

Go back and reread what I wrote before your post. I wrote about toe. Then you show up and use my words lol. Now I don't want to continue this useless back and forth discussion - it's not helping OP, but let me just point out that it was you who started condescending talk about "having a clue". Be a polite forum member and everyone will treat you like that, be a douchebag and you'll get what you deserve man

Correct. Only positive. I can't think of anything else. Assuming suspension components are OK and read out from alignment rack is accurate.

Except that your post says "I have no doubt is incorrect (negative) camber and toe that does the wear" and there isn't correct or incorrect camber and camber will not wear out the tires but toe will.

I was thinking maybe dynamic toe during acceleration or braking, something that wouldn't show up on the rack after settling the suspension. Maybe something worn or set up incorrectly that wouldn't be obvious without taking a pry bar to the suspension like ya oughta. It's also possible to get some extra toe-out during highway driving as well but not much. I run 1/16" total toe-out with 3.8* camber and there's zero wear over the life of the R1R tires. So it'd take more than that, I'm guessing.

Maybe I'm wrong, but I suspected that OP has way too negative camber (not just -2.5) and a toe - that combined eats inner portion. I thought one of his suspension components is either worn, broken, bent or isn't installed correctly - whatever it is - it is on both sides left and right, so due to that faulty suspension component essentially it's his wrong alignment that is eating his tires

Okay so basically I'm gonna tell the shop to move that towards the windshield and give more more positive caster correct? What confuses me is that the alignments readings say i have positive caster of over 7 degrees on each side. does this just mean i need even more positive caster? wouldn't the reading say i have a negative caster if it was negative? i'd just like to fully understand this before i go into the shop.

Would it help if i took the wheels off and took a pic of the suspension?

is there anything else i should consider? i really don't wanna go through another set of tires. i will get under the car this weekend and try to check out the bushings. do i just try to wiggle around the suspension components and check for any play?

thanks alot for your help on this btw

No need to increase caster. It'll increase dynamic camber that's helpful on the track but not really on the street. You would need to redo the alignment anyway. Lots of pics of the suspension would help, maybe. Get a length of 2x4 to act as a lever against the arms to see if the bushings are still good, well within reason anyway.

Appears that you plates are correctly installed. I have different plates but found photos online from them as seen bellow. At this point re-do the alignment and inspect the suspension components for failures as justpete suggested. I run -3.5 with 0.05 toe and tire wear is OK. I will post photo later.

Hm okay thank you. I will get under the car this weekend and report back my findings. I'll take lots of pics. hopefully i can find the culprit

This is my 255/35-18 Hankook RS-3 after about 8-10k (1year) at -3.5 camber with 0.05 toe and 10-12 track days. Wear is uneven, I agree, but considering the aggressive camber is OK. So inspect you components well and check the alignment on another rack if possible.

iturbo_bmw any update on this issue? I hope that you have it all sorted out.
