Does anyone know if the Impala SS 17" wheels fit the GN?
Nope. Wrong bolt pattern. And I believe wrong offset as well.
However, I think the ROH ZS6 looks identical and comes in proper bolt patterns and offsets for the TRs. An editor for one of the magazines (Hot Rod?) had a TR wearing these. Looked nice.
List member Preston Marshal has a set of the ROH's on his GN. Only appearance difference between these and the Impala SS wheel is the outside lip (where the wheel weights would go if one were to blemish these wheels with some)on the SS wheel is not on the ROH's.
The 93 and 94 Firehawks had those wheels in the 4.75" bolt pattern. I think they were 17x8.5"
