Jons 2004 Subaru WRX Chargespeed Super GT Widebody

I can’t decide between the 18x10 or the 18x9.5, I feel like I could utilize more rubber with the 9.5’s, I feel like I’d need to stretch the tire on the 10" a bit, where I can put a hair more to the ground with the 9.5? I have some spacers, I don’t know if I’m going to use them yet or not. I’m also trying to decide between rear camber plates or just notching the strut, I’ve had a lot of successful camber readjustments that way (I have an alignment machine at my disposal). The front fenders are +20mm and the rear are +25mm.
