M2 Rear Toe Arm Upgrades

Has anyone upgraded to toe arms w steel bushings i.e. the turner toe arms?

I wonder how much nvh they increase into the body.

I think the rear toe has a significant amount of flex that causes the car to waddle a bit on hard acceleration... I wonder if this would fix that.

I don't know what tires you're running but stiffer sidewalls and good air pressure could help.

Sure but does it actually reduce that rear end slop on acceleration?

The first 5 things I do to the suspension on all of my BMW's (and recommend):

Quality Coilovers
Camber Plates
Monoball Front Control Arm Bushings
Rear To Arms
Rear Camber Shims

The toe arms reduce rear end slop by deleting rubber bushings and converting to rod-ends. It also eliminates the finicky eccentric bolts for adjusting toe. Eccentric bolts are not as precise or easy to adjust as an adjustable toe arm. Not all are created equally. I highly recommend Fall Line Race Toe Arms. Additionally the camber shims delete the eccentric camber adjustment and replace it with shims which are also more accurate and easy to use.

I added the spl toe arm at one point with no additional mods. Apart from more adjustability, I don't see any difference in terms of driving dynamics

The reality is that changing to toe arms will have an impact but it's not going to be earth shattering. That's one of the reasons that I do the 5 things I recommended which will be a noticeable change.

Great to know! I was about to make a thread asking which SPL parts I should get first when I get some coilovers but good thing I browsed this sub-forum for a bit and I guess I will just start with your list.

We have sold and install many SPL version of the rear toe arms. Very minimum increase in NVH. Less toe deflections mean more power to the ground.

To install, did you have to lower the subframe ?

The waddle is real and it combined with what I thought was a massively sub par stock m suspension thay was very bouncy was the main reason I ended up selling my car.

I just assumed it was a naughty trait of the car that makes it a bit raw or exciting. I know my reaction and lateral grip is alot better with coilovers
