i was about to get a short-throw shifter myself but was putting it off til i had taught a couple ppl.
this is the 5th person i've taught and she's just not getting it, her lesson is over. my car can't take the abuse. after her the clutch felt softer. and i really don't want my flywheel eaten from shuddering at low revs. she couldn't even keep track of the rpm by sight, sound, or feel-that will just lead to stalling or red-lining the engine.
maybe the first 4 i taught had more fear in them of breaking my car since they were my gf, gf friend, and gf's 2 bros.
maybe more ppl are right-footed so working the clutch is tough. i've had upgraded clutches and it seems like that would be even harder to learn on.
can u imagine teaching someone and your clutch or something goes out..
