Ummm NO! Depends how you use it. If you, let's say, drive a Corvette with Borlas, and other mods, and drive to the max, obviously you'll need a new clutch pretty soon, and tranny, if you have lot's of torque. If you drive moderetly, you'll need one like after 200K. My dad had a 87' tercel Hatchback, 5 Spd standard, we needed a new clutch at 205 646 KM, I remember. WIth manual, it's fun, and you get the most out of your engine. There's no Transmission oil to buy, since it uses the engine oil, and it's easier to do burnouts, and corner. You can use the clutch to shift some weight of the car when you corner hard, unless you got Eibachs.
Anyways...... By How much are they going to drop? 20 bucks, 30, bucks, 50 bucks?
