I would likely stick with the sizes you have now, and get the best tire available in your price range, or wait a bit, and see what the RT615K is going to be like.
Upsizing can cause clearance issues that may not seem likely. If you're positive the extra width will clear, and can get the tire you want, then I'd say go for it.
The current RT615 is likely available in both the current, and contemplated sizes, not sure what sizes the RT615K will have. Falken hasn't released much "more than 20 sizes" as info, last I saw. No info about when they'll hit the shelves, either.
The Nitto's are a bit too geared for road course use for autox. They like a lot more heat than a typical run can generate, and the delay between runs always let them lose too much heat to be fully effective.
The Z1SS is considered to be one of the best ST class tires, but does suffer from limited size options.
Adding width, without adding sidewall height, doesn't usually lead to excessive flex. But, an increase in PSI may be needed.
Oh, for the record, it wasn't just camber that caused the wear. Negative camber, within reason, doesn't create much wear. It's when you add toe to the equation that wear starts becoming more pronounced. Just thought I'd mention that.
I have an FB, so the 205/50-15 is my best size. Dunlop chose to skip that size, and Hankook only offers 1 15" size, 225/45-15. I'm not 100% sure I could keep them away from my fenders, so I went with a new set of RT615's. Hopefully, I can get ahold of at least a couple of the Hankooks to test for clearance. I'd love to try the RS3 in a 225/45-15. The GC coilovers up front give me a bit more room, compared to stock spring size.
