17" versus 14" tires

You need to be honest with yourself with the intended usage of the car. After that, look at tire size and type in both (or all) sizes you are considering. Lastly, choose the wheel. Also remember that "great handling" is subjective. Sure a 15" wheel with some 1.03" bars and decent shocks will feel great when compared to stock, but that isn't anywhere near the potential. This all gets back to being honest with yourself.
