I have Nitto 555Rs for the Challenger.. Very sticky and awesome when warmed up and going in a straight line. For regular driving, should be fine as long as you're not cornering hard or driving in rain. And, of course, shorter life than other tires.
I have Nitto 555Rs on my Red/Silver GTS. I like them. Got them from a VCA vendor, $1000. Interestingly, I found that after my car sits for two or more months, the tires flat spot. However, after about 20 mins of driving, everything is fine. Not saying this will happen to you, but for me, I need to drive it at least every four weeks or so.
