Everyone of those is a big maybe. All depends on the service manager and how he wants to view any of those mods. My dealer will not even let me have aftermarket wheels and tires. Have to take it in with stock wheels on it for service. Really only had to go there once right after I got it for a update on the computer and the first free oil change. If any thing were to happen to the drivetrain on my car I would have taken it to anther dealer. The free oil change they scraped the lower plastic moulding swinging the arms in on the lift. Freshman mechanic issue. They did put a new one on.
