1. Camber Kills Tires
This is probably the most common statement about camber. There are a lot of people out there that think camber is the absolute worst thing you can do to your car because it destroys your tires so quickly. This actually isn't the case unless the car in question has very extreme, excessive camber. In many cases you'll probably find that toe actually wears on your tires more. Camber is typically used in racing applications to counter act the force of going around corners. However, this camber is minimal so you probably wouldn't even noticed if you walked by the car. People running crazy amounts of camber usually do it to fit wider wheels on their car and with extreme camber, yes it can wear faster. This is in extreme cases though. Most of the time, the small amounts of camber that you're running won't have too much of an effect on tire wear.
2. Camber has Function
We touched on this already but you'll come to find that when you talk to someone that has slanty wheels they will almost all say that camber provides function. While it does in racing applications, excessive camber on your everyday car probably won't benefit the car in any way aside from being able to fit wider wheels under the fender. You'll often see excessive camber paired with cars on air suspension but you'll noticed once they're aired up, the wheels straighten back out. The only time you'd actually have proven function of the camber is at a racetrack or an autocross event.
3. Camber Plates are All You Need
You can't go into this thinking that you can slap some cheap eBay camber plates on your car and get the slanty tires. You will have a terrible time. Believe it or not, there are a lot of adjustments that need to be made in order to make driving a cambered out car bearable. Do some research and find as many supporting parts as you can. If you can dial in your suspension components to all support the camber as one unit, you'll have a better ride and you probably won't destroy as many fenders and lips when you're driving down the road.
