Rim offset has a very minor, if any affect on the camber of the tire. What people are telling you is that if you have a low offset tire, it sticks out much farther, and if you have significant negative camber, it may cause the tire to rub as the outside edge of the wheel will be higher relative to the inside edge.
To fix this, you have to dial out some of that negative camber or open up the wheel wells. If you aren't concerned about running really high negative camber on the street, don't worry about camber plates. The only way to know if it will fit is to find somebody with the same setup, or test it yourself.
High amounts of negative camber on the street will cause the car to be darty at highway speeds driving in a straight line, could cause the front end to tramline, and will cause excessive tire wear on the inside of the tire. By darty and tramlining I mean that the tire will want to follow grooves in the road, and seem to want to pull from side to side, but not always to the same side as if the toe alignment was off. |
