i own a stock-ish (K&N, cold air) 99 GT with a 5 speed and am trying to work on the best shift points and launch RPM for the quarter mile, but am only just guessing at what is best. What should i launch and shift at to get the best 1/4 mile times? (on street 245/45/17s)
rev it up to like 3,000RPM and slip the clutch fairly quickly. When it grabs, hammer down mofo! Shifting at about 5500 RPM will most likely net you the best results. Don't forget to fill up your tire pressure in front and lower slightly in the rear (helping you to hook up better).
