Camber plates would be where I would start on a strut car like these. I'm shooting for around -3 degrees up front, running a square 305/30/19 setup. On the stock rubber with an aggressive street alignment, my car rotates, probably a little too much under power, and I'm going to add more negative camber and toe-in to the back to settle it down if the wider tires don't help enough. The front camber really helps pull the car around tight corners though. I tend to run as much as I can without chewing the tires up too fast.
Make sure there is no toe-in up front, that will induce understeer right on turn-in.
I am no expert, but I have had to make several kinds of cars corner better. Once in a while I'm even successful! Sort of.
