225 or wider on wider-than-stock wheels works, but not necessary.

Other Extreme Perf options likely to give you 95% of the performance with 2x the tire life, but pretty sure RE71R are still top dog for lap times/autoX times.

I think you just made my decision both easier and harder... Now I am second guessing my tire choice if I went with the tc105. I'd have a wider tire, but could then get a slightly longer lasting tire and that would ultimately give me at least as much grip as with either of the toyota wheels, but be better for the majority of the cars duty that is commuting. That could be a good compromise and makes me lean more towards the tc105.



I'm not too concerned with changing camber as I agree with you that it is in a good spot from the drop, just noting it because it makes the stock wheels look weird especially in the rear. I also just don't want to get into messing with that. I had a car when I was younger that I messed with coilovers, camber plates, and such on and it seemed the more stuff I added or adjusted, the more I had to add or the more problems it caused - wasted some of my best years obsessing over alignment and I just don't have time for that anymore. That's why I went with TRD springs as it was a factory option and can't be doing anything too harmful.
