We know that most of the 99-04 Mustang V6 guys have already added some more power to their mustangs. If you are running over 350 flywheel HP you should look into getting a RAM HDX or Powergrip clutch. Now would also be a good time to change the flywheel (we suggest a stock ford racing replacement flywheel). Looking for more upgrades, check out our 1999-2004 Mustang V6 Gears.
