Viperfreak2,
You underestimate the lap time delta between a Skip Barber instructor and the typical driver of a Viper, Corvette, etc.
To support my statement look at the Viper Days track times at Spring Mountain. Look at Modified group(10 drivers) as it is the largest. "Best" lap range 3:07.122 to 4:44 minutes:seconds. The 5th place driver's best lap time was 3:25. That is 18 seconds faster than the fastest in the group. My est. is that the Jeep SRT8 was about 5-8 seconds behind the Viper. Second Place was 3:15.056, almost eight seconds behind first.
But to drive this point even deeper with facts is that the NEON's fastest lap was 3:14.6(Nancy Stein) and fastest lap for the Viper Super Stock Class was 3:14.4
Fact is, the NEON was faster than 22 Vipers of 28 including high HP unlimited class! The Jeep SRT8 is much faster than a NEON!
You like most people do not understand the importance of skill and the impact on road course lap times.
