Since you said your car isn't and will not be lowered, I'm assuming you are on stock springs. I'm not sure what diameter stock springs are, but keep in mind when people run camber plates at the top they are almost always running coil overs since it's the easiest solution to lower a 510. Coilovers utilize a significantly narrower spring than stock springs. All that being said, with camber plates and stock springs you may run into the issue where the camber plate has the adjustability, but adjusting it that far will result in the stock spring hitting your strut tower. I'm not sure if this is the case, but I bet it if isn't it'll at least be close. I would do some measuring and if it the springs would hit the strut tower, you're best bet will be the LCA's and camber plates together. This will allow you to increase track width with the LCA which increases camber, then you'd use your camber plates to center the spring in the strut tower so it doesn't rub.
Also, if you have a welder you can make your own adjustable LCAs for pretty cheap by cutting the inner bushing off and putting a heim joint in, much like Ermish Racing does.
