I have found some rims for my car - just 2 steel rims but I need to know what the BS is on them.

I think they are 15x8 5x 4 3/4 but i'm not sure of the BS

Pretty sure that the other set are 15x10's - at least it was that close with quick tape measurement - this could be wrong.

Will these fit our cars? I have LS1 rear brakes.
