i just bought some 92 rs rims and they say front and rear inside the rim . do you have to put them on the front and rear like they say.front on front and so on . let me know i have an 88 i didnt think there was that much of a diff. if you could let me know . i hope i dont have to do a lot of modifications .

Yes. The rims have different offsets and you will run into rub issues if you use the rear rims on the fronts.
