Can you shift your E30 smoothly while shifting quickly? Looking for some perspective on what is normal for these cars.

The G240 behind your M42 will tolerate all sorts of abuse, and as long as your mechanical components are healthy you'll be fine to rip through all of the forward gears.
If you want tips on shifting I recommend Keiichi Tsuchiya's Drift Bible. While it may be an old video, the in cabin foot/hand shots interlaced with exterior shots will educate you.

If you shift so fast you feel the gears grind you are going faster than the Synchronizers can speed up/slow down the main shaft and clutch. This is a mechanical issue and there is nothing you can do but slow down the shifting. If you want to be smooth about it you need to shift just fast enough so that the engine speed is at the exact speed needed for the speed you are going in the new gear. For instance 6000 rpm in 1st gear is the same speed as 3200 rpm in 2nd gear, if you shift so fast that the engine has not had time to slow down from 6000>3200 and dump the clutch it is not going to be very smooth! The gap in RPM between gears gets closer as you get into the higher gears and it makes a smooth shift easier but that also means the amount of time between gears changes. This is something you LEARN by driving the car.

How quickly do you "need" to shift? The Getrags are decent boxes with well designed synchros....

250k before odo broke (engine same mileage) when we bought the car, then this video was taken after 4 14hr endurance races and about 12 Spec e30 sprint races. Nothing rebuilt in that car at the time...
