Nice! Those tires already look tight enough to the rear fender w/o additional spacing.

Your front ride height is low already for a street car. Remember, if the tires are larger diameter, then the additonal height (1/2 the additional diameter) needs to be added to the target ride height so you don't change the suspension geometry.

Thanks Bill, good point. IIRC, I had the front right at 150mm before and that's where it is right now. The new fronts are only .1" (or ~ 2.5MM) taller than stock, so I didn't expect it to be much different. The rear is another story, the new setup is about .7" (or ~ 17.8MM) taller back there. I'll probably try to raise the rear about 6MM or so, getting it up to about 173MM.
