It is hard to tell from the photo but yeah you can see the control arm pivot is definitely higher than the tie rod pivot. And if the models are out there then yeah, I agree.

You'll find steady state handling is quite dependent on static toe settings, and I almost always end up running some kind of toe out on MacPherson suspension setups.

I didn't realize the PBM cut knuckles reduce Ackerman. Either way I don't think that .08° of front toe in will result in catastrophic understeer. Going from zero toe to OEM spec toe in on my car helped tremendously with bump steer. Far more comfortable on the road, it understeers ever so slightly when brought up to the limit and initiating a slide is still as easy as before. With that being said, I have stock knuckles and OEM Ackerman.
