They could have taken out the tiny bit of toe in the E70 had to save fuel and tires but it takes away that sharp feel. I'm going to play with mine and add a touch of front toe in and see if it tracks better. Everything else is better on the F15. Its drastic. And the E70 is amazing on its own so those were big shoes to fill.
I noticed that, too. We had the pleasure of having both our E70 and F15 for a week and as I compared them there were definitely a few things I knew I would miss about the E70. I just handed it back over to BMW NA today and I admit it was a little sad. It was repurchased due to a dealer's many failed attempts to address the VANOS failure issue, but we loved the car and didn't have any intention of selling or trading right now.

They both have/had staggered 20" wheel setups, but I had to return the E70 to stock for turn in so today I drove it with the old non-staggered 19" wheels with the original Bridgestones, and man did it ever drive great. Big tires really are just for looks on these vehicles. For driving characteristics they grab every imperfection in the road and make the steering feel sloppy. I ran into some windy conditions on my 1400 mile drive home with the new F15 and it was a handful. I'm tempted to experiment the same way you are with the front alignment. There's no excuse for that kind of road wander on a brand new set of tires. I bet I could get the dealer to add toe in for free by complaining about/reporting bad driving characteristics in certain conditions.
