E46 M3 BAD tramlining. Need help.

[wahsm]

Toe-in is recommended on a street car to avoid tramlining. That said, even on a street car, I would still set front toe to zero and the minimum toe-in for the rear.

This is what I had before a more aggressive alignment for track and it is great for street use and some more spirited drives. Not sure where they are getting those min and max from for "in spec". Looks way off to me.

Toe-in should 'help' against tram lining in theory.

I have attached the normal M3 as well as the CSL specs in images.
If you use the CSL specs, which have very little toe-in on the front and rear, close to 0 as others have recommended, the car will drive great.




Furthermore, I had a similar issue with a set of 245s that I ran up front that just wouldn't stop tram lining, I ended up just replacing them and the issue was gone entirely.

I'm just mentioning this cause I chased this issue on a Audi I had. When installing the trailing arms they weren't clocked properly and then tightened. It caused crazy tramlining. I ended up properly installing new trailing arms and all was good.

You can chase your tail with these issues but start at the most obvious and easiest which seems to be the alignment. Take it to a better shop

I might just be very picky, but your final settings kind of show me that your alignment shop either isn't very good or just aren't putting a lot of effort in. I know the factory adjustment isn't exactly user-friendly, but at the very least there's no reason the front shouldn't be uniform left to right.

Also, this could just be from suspension upgrades directly prior to alignment, but has your car been in an accident?

Based on your post-settings and you still having the same behavior, it does sound like possible issues with your steering rack and/or weird issues with your front tie rods.

Okay so what should the toe be? As close to 0 as possible? I thought some toe is normal?

[FBloggs]

On top of your excessive toe is the tire wear caused by the former.
I run 265 square w/o tramlining.

It's your streering rack, rebuild it or upgrade it to a quicker ratio...

I guess this makes sense. I will tell the alignment shop. What doesn’t make sense though is that the toe is within range, unless their range is messed up. I do not track the car also.

[wahsm]

This is interesting, but it seems the toe is within range still?

Do you track the car? If no, I would zero out front toe at least. Actually just noticed they are both positive toe which is a bit weird. They try to sell you tires as well?

Here are the recent alignment results

You have an unnecessary amount of toe on the front AND rear of the car. That's why it's tramlining like crazy, because the super aggressive toe is following the road front and rear. You need to go back and ask them for zeroed out front and rear toe. That much toe will cause tire scrubbing and wear, mess up your fuel mileage and make it drive like shit.

Get it corrected ASAP and the car will drive much better.

I did 4 wheel alignment too after the control arms tie rods and rtabs. I will get the photos and post.

245s shouldn’t be enough to cause severe tramlining. I have 245s up front on ZCP wheels too, and it’s not an issue for me.

Get an alignment.

Also, check steering for play.
