I used to downshift all the time with my V8 Grand Cherokee which doesn't help big time, cuz the car is so heavy...(with at least 500lbs+ mod on lift, and bumper). I AT is however doing very well, but I do change the AT at least 4 times with Amsoil within the 120,000KM, after every 4x4 season.
Anyway, I also downshift 200% of the time with my STi (stick shift only) since day 1, of course I rev match as perfectly as I can. as far as I concern, the clutch is still strong, and my brake is at 50% (with a little track day + autoX), car is at 33,000 miles at this time.
