So I wasn't sure if I should post this under suspension and steering or wheels and tires and brakes because it is impacted by and affects all the above.
So without getting into the debate over wheel spacers and if they are a good or bad thing which is a separate discussion, when they are installed on a vehicle one of the arguments in favor of them is wider stance improving traction and rollover resistance. However, this can be true but may not always be when accounting for scrub radius and how it impacts tire contact with the road.
I'm not great with the technical calculations but I know some on this forum are so I thought I would ask:
Do we know what the stock scrub radius is for the OEM wheels and tires and suspension components? I'm assuming this changes with the various ride heights and that would also further complicate that calculation as well as those that follow.
But if we do know, or if someone is able to calculate it, then is anyone able to further calculate how different common wheel spacers (let's say 0.5", 1", 1.5" and 2") applied to the stock config would impact scrub radius and traction and if they would theoretically improve or worsen tire contact and handling?
Any way to calculate how they would impact rollover resistance?
Wondering what the numbers say the impact of wheel spacers would be on these figures when you actually run them for this vehicle assuming no lift kit, no change in wheels or tire ratios, just to have a list posted somewhere for reference for those considering them for whatever reasons they may have so they can make an informed decision since we are starting to see people post photos with spacers and more tire poke on the forum. Even rough estimates might be helpful so people can make informed decisions about how spacers will actually impact vehicle handling rather than theoretical ideas that may or may not apply in this case.
Thanks in advance for anyone who posts replies that attempt to take on this challenge. Seems like it's something that should be listed on this forum somewhere.
I'm a truck n00b but since so many people like to modify trucks to their liking and this is a common one that can have some counterintuitive end results that may not be what people thought they would be I'm hoping a thread to crunch the numbers for this vehicle may be helpful... but if we collectively think it's a waste of time school me on that as well.
Cheers
