My "new" 2006 SC 430 came with a set of brake repair parts for the rear brakes in the trunk, including rotors. It doesnt need them but the 2004 LS 430 could use new rotors on the back. Will the '06 SC Rotors fit the '04 LS

 

Pretty sure they won't. Comparing parts on Rock Auto and I don't see the same part numbers between the two models.
