I am getting major wear on the inside edges of both front tires. Replaced control arms, struts and strut mounts over the last year. The car tracks straight and I didn't have this problem with the first set of tires. Is this normal or is the toe way off? Second question: When the car is idling and then I give it some gas the headlights and dash lights brighten up. Is this indicative of a bad battery, voltage regulator or alternator? Or is this normal? Thanks in advance.
