Most if not all of these items can be addressed and mitigated *sp* as much as people like running squared setups I typically don't as per my driving style at the track.

Bullitt, I'm planning on a 275 F / 285 R on 20x10 +35 and 20x10.5 +15 rims. From my understanding-
Bump steer: Increases when the rim face is extended further from the pivot point, increasing leverage. With increased offset on a wider rim (+35 on a 10" vs +22 on a 9.5") the maximum lever arm would be equal, therefore no increased bump steer than the narrower wheel. People seem to feel the 9.5 + 22 is acceptable.
Understeer: Everyone except yourself has stated that a wider front tire will reduce understeer not increase it. I have Stillen sways and the front still pushes.
Slower transitions: True, but I will be autocrossing with my original sport rims not the wider 20X10 front I'm planning on getting. I don't expect many violent transitions on my daily commute.
Slower accereration: I believe this will be negligible with a quality lightweight rim.
A 255 section width tire is designed for a maximum 9.5" rim width. You run the same tire on a 10" rim, outside of the designed application.
You say more tire up front is bad, yet you want to go to an even bigger 285 tire in your next setup.
Bump steer is bad, but you want to extend the rim face out even further on a 11" front rim when you install the widebody.
You don't like square setups. Why do all the racers use them? I don't need bigger tires in the back, I don't have 1000HP (I am jealous though)
Don't get me wrong, I know you have the most badass car on this site, and definitely know more than I do. I just hope you could straighten me out on what appears to be conflicting information. Please don't look at this post as an attack or insult in any way, I'm just looking to understand.
