I posted a thread early this year on dba rotors, I contacted dba here in Sydney & they are aware of the Stinger & advice to me was they expect to have something by years end, they already have the Stinger in their system but parts are still N/A. The 5000 Series is a 2 piece design. I have added the link so you can check it out, I hope this is of assistance to you. HOME FRONT PAGE
