Biggs: Listen to Angela - makes a lot of sense, especially THIS part:
"How long should a clutch last? On a stock engined production car - a long time. The last clutch I had put in a personal driver was in our Mazda MX6. Stock clutch went 276,000 miles. If you are getting 2 months out of a new clutch, you have a DRIVER problem."
Amen....
When my Dad had school buses, two people, in particular, stand out in my mind; One driver would get 130,000 - 150,000 miles of stop-and-go driving on a stock, factory installed clutch. She was a terrific driver. The other driver was a hot-shot (we found out) and I was replacing clutches at 12,000 - 16,000 miles. Not a fun job on a school bus - tranny's weigh over 150 lbs. The "good" driver was with him for almost 20 years, while the "bad" driver lasted through 2 clutches and was shown the road.
Proper clutching is not an art, but the clutch is not a "hill brake" like in an automatic, either.
