Will the wheels off a 09 camaro fit 08 impala ss?

No, the wheels from a 2009 Chevrolet Camaro will almost certainly not fit a 2008 Chevrolet Impala SS. While both are GM vehicles, they have different bolt patterns, wheel offsets, and likely different hub bore sizes. These dimensions need to precisely match for the wheels to fit safely and correctly. Trying to force incompatible wheels onto a car is dangerous and can lead to accidents.
