Anyone Master Downshift Rev-Matching

I'm going to say that trying to save the synchros is overkill. For me, it's all about smooth changes and driving pleasure. It's just a nice fringe benefit that it saves the clutch if done well.

So, assuming braking is involved:

1. Lift off throttle
2. Apply brake and clutch in at roughly the same time (being sure to position your right foot on brake pedal so that you are ready to blip throttle while maintaining brake pressure)
3. select new gear
4. Blip throttle and then immediately pop the clutch out

If you're just coasting down without using the brake, or downshift for an overtake or whatever then simply change "2." to "clutch in".

Having said all that, putting this into a list is somewhat misleading - there's overlap in places and the whole thing is more of a single flowing process, if done well. Obviously at the outset you're going to nee to break down the steps. But the aim should bea nice smooth process and a gearchange where you can't feel the clutch being fed in.

Sorry, you are wrong. The idea behind rev matching downshifting is to save both the clutch and the gear box. Your advice will kill the gearbox.
