You new GSR owners are launching and shifting your cars all WRONG!
To get the most effective lauch in a GSR you must launch above 3.5K rpms; either do a slip launch or drop the clutch while feathering the gas. Once your used to lauching at 3.5K rpms, try launching higher because it will be more effective. Ask all the guys who get 2.2xx 60ft times, they will all say that they launch at atleast 4k rpms. As far as shifting point in a GSR; in 1st gear you want to shift as close as possible to fuel cutoff(8200rpms) and shift quickly into 2nd gear, this will only allow the revs to drop to about 6krpms and will allow you to stay in the secondaries. New beginners will have a hard time staying in the 2nd gear secondaries after the 1st gear shift, this takes practice.
From then on just shift each gear at redline. THis is how you will get good times and beat the other guy.
