I lowered my car about two months ago using the B springs (got about an inch at all four corners), and everything runs fine. The car deosn't pull left or right at any speed, nor at braking. However, I do believe that my toe camber (if that's the right name) is bad. The reason is that the front wheels are leaning towards the inside of the car a little bit. I don't want uneven tire wear, nor an unsafe car, so I figured I'll need an alignment. I was wondering if a shop can fix this with the standard setup, or if I'll need to spend more money and get those plates?
A little toe won't kill you, but if you notice any steering wheel shaking or uneven tire wear, you would just need an alignment. One inch is pretty much nothing, and you really wouldn't need C/C plates until you get real close to a 2" drop.
