rx7legend

hi, i was just wondering if someone here is running them or have had them. im asking because my bro has a complete set of 17x7'5 and i was thinking of getting them and painting them flat black, they're lightweight so they're good for drag ocassional racing and that's what im looking for. they're mounted right now on his project car, is a 1992 eagle talon but hes letting me have them if i want to, anyone know what kind of offset have these wheels just by seeing that there on an eagle talon???? i try to search but couldn't find anything on offsets for this wheel. these are the wheels im talking about.

thanks for any help
