I think the price from your dealer is pretty close. You might be able to find a better price from a race shop dedicated to this type of work. Oh and clutchwear is solely determined by the driver! A driver can significantly reduce a clutches life!. A normal daily driver car, let's say an escort, the clutch could last 150,000 miles! With the wrong driver it could be toast after 10,000 miles!
MPE racing has specials on tranny rebuilds sometimes especially if it's gotta come out, give them a call, really! 1-508-824-6322
