Maybe its the suspension then. PO told me it was set to full soft. It has a stupid amount of adjustment.

Default Re: E36 M3 rear end feels "loose"

Just wanted to check back after all of this time. I got the car aligned on 1/24/18. (I know I waited forever) and the car feels pretty good so far. I moved so I don't live where I used to where I had the same kind of turns but the few I have done the car feels a lot more predictable now, and does not seem as loose anymore. Figured this might possible help someone diagnose a similar issue in the future. Here are my before and after alignment specs:
Before:
Camber:
FL: -1.6 FR: -1.9
RL: -0.9 RR: -0.7

Toe:
FL: +0.27 FR: -0.06
RL: +0.12 RR: +0.07

After:
Camber:
FL: -1.6 FR: -1.8
RL: -1.5 RR: -1.5

Toe:
FL: 0.00 FR: 0.00
RL: 0.00 RR: 0.00

Interesting. I see people go to zero toe front but not zero toe rear.

Before you had less than optimal rear camber for handling.

Yeah it seems that was the case. I have been doing 0 toe front and rear since probably sometime in 2014 starting with my E36 328is. I then did that on my E46 330 daily I have now and now did that to my M3. I love the way it feels. Some people say to do a bit of toe in on the rear and I may decide to change that. I want to dial in the front camber a bit more but have to drop the struts as one of the 4 torx screws is hidden behind the strut tower lip at its maxed out positive camber. I always do the firestone lifetime alignments so I am always open to making changes. I brought my 328 there probably 8 times a year lol.

So pushed the car a lot today and it was doing a ton of understeer assuming this is due to the big bar upfront.

You have stock size staggered front and rear tires and wheels so you should expect understeer.

I have 225 upfront and 255 in the rear so maybe that in combination with the bar is the cause.

I think the bigger bar is supposed to help the front end, but it’s not going to make it better than the back end especially when you have exaggerated the stagger with even bigger rear tires. Put 2 rear wheels on the front with 2 more 255/40/17.

What is your ride height. If you are lower at the front, you will get understeer.

I have never understood how stiffer sway bars at the front reduce understeer.

Also, try reducing the damping up front.

The dampening is fully soft. The front is pretty low it runs sometimes over bumps as does the rear with that figment. The alignment reduced the rubbing. I bought the car at this height but have neglected to change the coilovers.
