You can find walkable, safe neighborhoods all across the city, so it will likely come down to the location of your work, and the type of lifestyle you prefer (laid back, in the scene, family life, etc.). I live on the west side myself, so I'll speak to this area.
What is a Concave Wheel? Concave Technology takes the center of the wheel and dips inwards to give it that bowl effect. Rather than exaggerating a bigger lip for the back wheel, and a smaller lip for the front. Concave wheels emphasize the concavity of the rear wheel to differentiate from the front wheel.
The term Centric refers to the way a wheel is centered. In other words a hub centric wheel centers on the hub of the car, if you put the wheel on the car without lug nuts the wheel would be perfectly centered. On a lug centric wheel, the wheels are centered by the lugs as they are tightened down.or example: the center bore of all 4x100mm and 5x100mm wheels is 64mm. However, the hub diameter of the Honda is 56.1mm. Therefore to take up the space between 64mm and 56.1mm a hub ring is used.
