Any idea on how toe relates to torque steer? With my current setup  I’m experiencing zero torque steer. I’d gladly sacrifice a little premature tire wear to having my steering wheel yanked out of my hands whilst going through the gears. Thanks!

In my experience, toe has more to do with edge wear than camber, but I am not a racer.

You are correct. I don't know what I was thinking. I'm sure of my 1.5° negative camber and toe @ 0 mm. With those settings you would indeed expect wear to occur on the inboard side of the tire. On the other hand, I've recently experimented with shock settings and tire pressure [link] and settled on a soft shock rate and much lower tire pressure. So, perhaps the outboard tire wear can be attributed to soft tire pressure and soft shocks along with some admittedly aggressive cornering. 

I'm happy with my new (lower) tire pressure. While I wouldn't call the ride smooth, it's much smoother than when I was running the sidewall recommended pressure. I know the pressure isn't too low as the scuff indicators haven't come into play (see pic). I suppose if I wanted better tire wear I could decrease the camber another degree or so. I reluctant to do that because I am currently enjoying having zero torque steer and don't want to risk messing that up. Maybe 8k to 10k miles on the Yokos is all I can expect.

I've been getting 7k to 10k miles on a set of Yoko 032s by rotating them front to back @ 5k miles. I think that's reasonable mileage given how soft and sticky they are. 
 
Unfortunately, my current set has one tire that refuses to balance. My alignment guy says that it's a factory defect and it happens sometimes. The bad tire is on the rear where it is tolerable. If I rotate it to the front, it becomes unacceptable.

I've got 5k miles on my current set and the fronts are worn out on the outboard side. I run 1.5° of negative camber so that's to be expected. I'd like to try swapping the front left and rights, keeping the rotation the same and see if I can get another couple of thou out of them. My tire guy will make the swap but won't commit to the effectiveness or safety. Any thoughts…?
