In addition to the handling reasons listed, I think one reason few people run 275 or wider in the rear is that there aren't any good 17" street tires above 255. You can run a crappy tire in 275, but you'd be slower than the top tires in 255. You can move to 18" and start getting up to 275+, but then you are looking at increased weight, increased wheel cost, and significantly increased tire cost, on top of the possible fender work. I think most people would rather move to R-comps than spend $3000+ to get 20mm more street tire.

Adding tire up front is a cheap way to make the car faster. Whether people want all the added grip up front or want to move some of the added grip to the rear using a thicker front sway is a matter of taste. Going nonstaggered and re-balancing with a thick front sway doesn't put you back where you started. It gets you the stock-like balance, but more total grip and more total speed. That's why people do it.

Are you saying you want proportionately more grip in the front than the rear? This can't be the case otherwise you wouldn't change the sways to add grip back to the rear.

At a certain level of driving, you need more tire up front. You can throw tons of camber at a non-staggered set up and try to get it to work, but in our experience, the balance just isn't there for more advanced drivers.

There is a reason that most of the fast s2000s are on non-staggered setups - it's faster.

^ This. To me "advanced drivers" means guys that know how to use heavy trail braking into corners (using the edge of the traction circle) and skinny fronts can't hack it without overheating much more than the rear.
