I have an 82 GS, and found some wheels with the correct bolt pattern, but am not sure about the backspacing and offset.

would these wheels fit?

Rim Diameter (in): 15 in.
Rim Width (in): 7 in.
Backspacing (in): 5.375 in.
Offset (mm): +35.00mm

 

Too much Backspacing. Most of the guys are using a 4.25 - 5".

 

that's what i was afraid of.

at their current price they seemed too good to be true
