You don't necessarily need to shift into first at 30-40 MPH, but I would say it would be *nice* to be able to downshift into first going faster than 5mph. My WRX will grind while I try downshifting going 10 MPH. I've been happy with the transmission overall, it's just the first gear syncro seems to be the weakest link. Double clutching(release the clutch between gear shifts) does not help in any way. Rev matching helps a little bit, but it's also very picky, and a lot of the time it will still grind.
