Hello will factory Fuchs 7s and 8s fit my 1983 SC?

 

yup very nice look actually and very desirable.. pricey for 8s

 

Yes they fit fine.

but depending on ride height and suspension spec they can be tight at the front lip.

using a shorter tire like a 205/50 helps a lot but some lip work may be needed.

there is a ton of room in back 225/45 on 8 is the best match for a 205/50 on 7 front.
