Question about Rev matching

As I understand it, rev matching occurs when down shifting. As the clutch is depressed and the car is taken out of gear, the throttle is blipped as the gearshift passes through neutral. Then the car is put into gear. Can any damage occur from doing this? It makes shifting much smoother and I would imagine places less wear on the clutch.

downshifting isn't the best thing for your tranny. rev matching makes it a little better. When assuming you are speaking of downshifting to help decelerate (engine braking), there are two ways to do it. One is to heel/toe and revmatch, the other is to just let the clutch out slowly which will match the revs for you (the clutch will slip until it matches).

While the second way will end up smoother, in most cases, it's also will use up your clutch more.

Revmatching is a little better on your clutch. But then again, I'm of the opinion that downshifting should be reserved for times that you really have to decelerate quickly. Brake pads are a lot easier (and cheaper) to replace than a clutch.

the car should be traveling at the same MPH speed with higher RPMs due to the lower gear. Then you can stomp on the accelerator and take off.
