I personally run minimum factory toe front and rear, and am pleased with having more responsive turn-in, without any perceived degradation in straight line stability at normal freeway speeds and more.
Thanks, I actually changed the specs for my alignment to an M3 for comparison before I finished. The M3s run 10' of toe both front and rear, compared to 18'/14' on the 335i. So a good amount less toe-in on the front axle.
I probably will change to the M3 toe spec in the future. The only reason I didn't on Friday was that I was short on time and the rear axle was already dialed-in from my prior alignment. You're right, though -- too much toe-in will cause wear on the outside shoulders. I just didn't like how little front camber the car had. With the M3 arms, it's now almost identical to my E46 330ci.
And yeah, I actually run almost zero front toe on my C6 Corvette. I didn't notice any stability issues at all on that car, and tire wear has been great. That car is more of a weekend toy, so I went more aggressive on the alignment.
