Anyone use rev matching on downshifts? My 2005 wrx only has about 450 miles on the odo. so ive been watching myself, not pushing it or anything until the break-in is over. I'm still getting used to the clutch and sometimes let if off a little too fast (car jerks), but when I downshift I try to rev match as much as possible to take away the pressure put on the tranny from engine brakeing. Anyone else do this or it really doesn't matter if I do it or not. Any pointers on trynig to "preserve" the tranny. I know no hard launches or stuff like that.
