Va Maddog Posted July 24, 2005 Report Share Posted July 24, 2005 In 2001 you could order an STS with an option package that included 17" chrome wheels from the factory, an upgrade from the standard 16" wheels. My question is when they went to the 17" wheels did the factory also adjust the axle ratio's? What I'm really wondering is would the net affect of the 17" rims be a slightly lower hwy RPM more similar to that of an SLS and thus a little better mpg on the hwy? Does anyone know the answer?
