even with the 225'a you'll need an alignment.

in its basic form, each wheel acts as a lever on the suspension, where the offset of the wheel is the length of the lever, and the weight of the car is the force being applied. if you increase the length of the lever, less force is required to stay in alignment.

your current setup has a lever with length X and a force applied of M, and is considered in alignment, A. if you increase to X+Y and keep M static, you'll end up with A+wonky, where wonky = not fun to drive at all. low level wonkiness results in premature tire wear and tramlining. at higher levels of wonky, the dynamics can be dangerous. the only two ways to compensate are to reduce M enough to negate Y (this would be a serious amount of gutting, equally, left to right simutaniously), or change the effective shape of the lever (get an alignment).

this is important. if you change your offsets (or more specifically track width) by more than a few mm... get an alignment.
