Ring gear became separated from disk causing an intermittent starting issue. Joe at Zspeed figured out the problem, but I didn't want to wait for repairs so I just had him install a new flywheel. I then sent the flywheel to Fidanza to have the ring gear replaced and a new insert installed. The flywheel was tested to factory spec and will include receipt for repairs. I purchased the flywheel from Coz in 2010. Weights 11.5lbs. Asking $225.00 shipped. PIC [ [ [ http://i86.photobucket.com/albums/k89/stankonia37615/DSCN06671.jpg ] ] ]
