It's long been the stance of GM and other OEM's to watch what's happening in the aftermarket and build those modifications into newer vehicles. That's exactly why we now see 20" wheels as commonplace, taller trucks, factory running boards and bed covers, in-bed lighting, performance cars with factory superchargers or turbos, etc. I'm glad it's seemingly carrying over to engine bay appearance.
Not sure if this is entirely true,because GM has always been late to the party,but they are getting better.
People have been crying for 20 inch,8 lug dually wheels for at least 10 years,but all we hear are crickets.
