[H.G.P.]

I'm not that experienced with the understanding of the "redline". The redline on my tach is 7000. Is this something I should:

1. Stay below at all times?

2. Unsafe at certain gears?

3. What is the max, speed per gear (5 speed here), that I should have on my 911 E for each gear?

4. And is there an ideal shift speed through each of the gears, or is this a function of RPMs?

Thanks.
