As has been mentioned if you just like racing F-bodies then that's cool.
What about N BOOST
I don't like to be that bold (with reference to something degrading about a brand X vehicle), even though I have a 10-second Mustang LX with a plate that reads WA 2 FST. Still, there's always someone faster.
On my Cobra I thought about GOT JUC since its got a small shot of spray, but then its not stealth anymore.
ZR WHAT is one I saw that I thought was clever (I'm in TX, too) but that was back when ZR-1s were seen more often.
I ET Z28 or Z28 ETR
GM KILR
