aluminum flywheel

  1. 2005-2010 V6 Mustang Tech
    I just got a new clutch put in so I thought i'd have an aluminum flywheel put in while I was in the neighborhood. Anywho ever since my car makes some grumble in idle and at low rpms also when I hit higthspeeds (100+ mph) it sounds crazy loud and the car vibrates alot, this was not the way prior...
