Downshift to first in z51...
Ever since I found out that I can do 50 mph in 1st gear in my z51, I have been downshifting from 2>1 as long as I am 30 mph or below.
I'm not worried about the redline, and the car seems to handle it just fine. But do you think this is too much stress on the drivetrain or anything else? I guess if that TM module really exists, then maybe it makes it safe? Does anyone else do this?

I've done a downshift from 6>5 @ 116 mph. 6>4 @ 75, etc. it provides a nice bump in accel.

If you don't try to rev-match the engine, you are causing a large amount of wear on the synchronizing 'clutches'.

If you are doing it to use engine braking durring normal driving, I would only point out that brake pads are much less expensive than clutches.
If you are doing it on the track to get power out of the turn, then try to match the engine RPM to the down shift gear at that speed. This will keep RPMs up and not over stress the clutch.
Generally, brakes are for braking and down shifting is for power after a turn.

You can generally rev-match the engine and driveline by giving a large amount of throttle for a very short period of time (say WOT for 0.2 seconds) We generally call this a blip of the throttle pedal.

I do this too but not quite so much from 2 to 1st gear.
