12.3 @ 109 possible on street tires?
well last sunday at the test and tune night i pull up in line next to a guy with a red 99 z28 that looks and sounds stock...it was an auto like mine..we were both running Eagle F1 street tires..when we lined up in our lanes i had a near perfect reaction time and he pulled about 3 CARS on me from the go and his car sounded stock and he was on street tires and ran a 12.3 @ 109 to my 12.8 @ 109....how is that possible i know there isnt much improvement in my driving....could it maybe be a stall? i know for sure he didnt have a cam because his car was way to quite
