Who cares besides folks who live their lives in the pages of Motor Trend and never get out to do any real racing? Don't be so cheap and get a set of real wheels and tires for the track. Real racers know better LOL I learned that lesson 10 years ago, but it did take real world experience for me to understand 600+ RWHP cars need purpose built tires at the track. It makes you look silly to those in the know just FYI so if you're in to that kinda thing best not to post it all over the forum haha.
Ok, that last comment may be a bit harsh, and I'm kidding, not really, but seriously
If the ZL1 never gets out of the 11s on stock tires, well.....feel for you guys as it sounds like that will be your benchmark and it's really limiting potential.
