Why not give the
Nitto NT555RII a fighting chance? It has great traction for the mere 700-ish rwhp that you (and I) deal with, and having had those R888Rs, unfortunately the innocuous "road noise" term in the above posts is quite the understatement---think monster truck with chunky a** tires whining to the extent that it's hard to carry a conversation in the car.
Now, I'm sure there are people whose engines are so loud they can't hear the R888Rs over that or simply don't care, but you said your Camaro was a Saturday night special, and as such, I'd imagine you may often have a passenger, too.
The other thing in my experience with the R888R is that it was better than the PS4S in straight line dry traction, but not
worlds better, for example I couldn't just mash the throttle from a dig even when I aired the tires down to 24-25 psi. I understand it's okay to go below that on a drag strip, but then again, you didn't state that as one of your goals.
