Second is the Ring press release and comments by Bill Wise. This was his 125th lap in the ZL1-1LE as they worked to tune the car. "With chassis adjustability unlike any vehicle in its peer group" is Al's opening quote followed by "To make up more than a second per mile on the Nordschleife compared to the ZL1 automatic is a dramatic improvement and speaks to the 1LE's enhanced track features."
Tires alone didn't transform the Viper into the king track car...ACR nor the Z06 Z07. Tires alone won't transform your base ZL1.

+1. Driving is a team sport. Driver, chassis/suspension, drive train, aero and tires when properly tuned and synchronized will produce a very high level of performance.
Dreaded football analogy; You can have the greatest QB, WRs and RB on the planet, but if your LT stinks, much of the potential is lost.

I look forward to seeing how my regular ZL1 stacks up against the new 1LE in the near future on track. I know that they also use different ( non Magnetic) adjustable dampers and sway bar and camber plates will be an interesting comparison for me.

With all due respect. DSSV is unlike anything that I have personally experienced before.
Sublime is the only word that I can come up with to describe it. ZL1 is a world class sports car, yet IMHO it is the sum of all the parts and variables (driver included) that make the ZLE a superior "Ring"/circuit car.

Size and contact patch make a huge difference in times around a track also it would be interesting to see Bill Wise drive the regular ZL1 around the ring and see if there is any time differnce also.

3Rs are amazing. With that said they are RDOT. They are not competition tires, they are street legal R compound tires. Both the ZL1 and ZLE (extremely capable vehicles) will perform better on RDOTs.
The difference being that the ZLE suspension is specifically tuned for the enhanced grip of R compound rubber, which in turn enhances the performance capabilities of the car. IMHO, in the right hands, that setup will consistently produce noticeably better times (same driver, same day and conditions).
No disrespect intended. Just my humble opinion.
