You being a wiseass or just a dumbass?



The only times I can find is Motor Trend with 14.8, I was wondering if someone has stock times. Some kid with a supposedly bone stocker ran 14.5 at my local track. I am guessing that would be about the times they run.

I saw a 92 camaro with no mods whatsoever run 14.3 on the stock all-season radials. It was an automatic car left in OD to shift itself and the air was in the mid 60's that night.

There is definitely a freak factor involved with the stock L98 cars.

Extreme minority - Very low 15's

Minority - 15.0 - 14.8

Majority - 14.7 - 14.4

Minority - 14.3 - 14.0

Extreme minority - Very high 13's

14.38@95.whatever when i first got the car.
14.28@95.whatever with just the randomtech stuck on the back.

Guess I'm a minority.
If I add tires though I think the cars got extreme minority in it.
