when i took my limited roadster down the 1/4 mile i was only going 90 by the time i crossed the line i was racing my did in his silverado and i had enough time to read the whole sign after he crossed the line before i crossed. his truck has a 90 mph speed limiter!!!

my car is the factory limited convertable its a 2006. its the 5 speed autostick thing.

give me some advice whats the best set up for getting of the line

spoiler up or down
manual or auto
should i rev the motor while holding the brakes also
and if so what rpm should i be at when starting

my car took the track in 16 seconds i know the convertable needs reinforcement and that makes the car heavy but that shouldnt add 3 seconds to my time

i have a dirtbike that can cross the line in under 6 seconds so thats a huge difference
