I've been in photoshop to give you all another opportunity to mock this setup. The first picture is stock (not my car). The second is stock suspension and I photoshopped the tire/wheels about 2" smaller in diameter, note the ~1" drop in the car's height. Finally, since this added 1" of fender gap, I did a 1" drop to return the fender gaps to stock.

Now you can all mock, and you probably will, but I think the last photo looks like it means serious business, even with the stock style wheels. I think the first photo looks jacked up and oversized compared to the last. I admit the small tires with the stock suspension is a little wonky as predicted but I can easily live with it.

 

as far as abs and traction control are concerned i would have to believe that yes those would react differently with that tire size. both components are reacting to individual wheel speed which will be off because of the new tire size. if your computer isnt reading the correct speeds at each wheel it will not be reacting like mazda intended. will it be noticable? maybe not but yes it will be affected
