Lightened Flywheel, 12lb or 9lb

oh! and plus, i dont know if u know what "heel-toe" is, and how it is done(when u shift down gears u use ur right toe on the brake and ur heel on the gas while stepping on the clutching with ur left foot). people who go to autox or people who really knows how to drive should know how to do this. i dont know about other cars, but once u have the 9lbs or lighter flywheel on ur civics, u wont be able to do heel-toe on ur car becuz when u downshift, ur lightened flywheel and clutch wont be able to slow the car for u. (cuz when u downshift and let go the clutch, the engine's backpressure slows the car down)
