yes , all the trans dapt adapters says "sema" on them. i felt good about them at first. coincidently, i painted them black when i put them on. a month later , i took my wheels off to check them, low and behold my passenger side front had a decent sized crack that i could see because of the black paint. this is normal everyday driving, no huge bumps or potholes. prior to putting them on, i had taken the drums off and scuffed them real good , so i know the surface was a perfect as it could get. as Okla says, some are good , some arent. i also know another guy that ran them with no problems, but im sure some slip out that are defective.
