down shifting

It seems to me that you need to learn to blip the throttle. .

"Blipping the throttle" does absolutely nothing to help save the syncro rings. Unless the clutch is dragging, and that in itself is hard on them.

You must DOUBLE CLUTCH and use (blip) the throttle for engine RPM to affect syncros.

But this thread is more about the OP being ABLE to go from 4th to 3rd at a reasonable speed and RPM, something he didn't seem to be able to do.
