Speed to set suspension to "low"

I find it interesting that the speed by default to set the suspension to low is 100mph. A little too fast for 99% of my driving. Yes, I have taken the car over 100 mph, but only for brief moments. With that said, it is common for me to drive in the 80 to 85 range.

What I don't have a feel for is exactly how low the car is relative to the roads in Illinois and Indiana. If I am over 80, it is only on the highway. Should I feel safe lowering the car at that speed?

Thoughts?

100mph is NOT the default setting. Set it to whatever speed you want and go on with your life.

When my MX was set to low the inside rear tires wore out quickly. A little research uncovered that lowering the suspension causes the tires to toe inward. Speculation is if you know your almost never going to need go above low, you could have an alignment done to account for the inward toe. In fact, that is what my ranger told me Tesla already does, so I could just leave them in low. But, then why did my rear tires wear on inside like so many others have reported? Lastly, I have no idea if this issue still holds with the new Raven suspension. I believe Zack and Jesse on Now You Know documented this on their MX if you want to search their youtube channel.

hmm,, I just realized this is in the MS threads. I am not sure the MS has the same issues as the MX, but my guess is that they do.

Okay I will bite, how does lowering the suspension increase tire wear?

It increases the wheel's negative camber. The tops of the wheel will be tilted toward the vehicle causing increased wear along the inside edge of the tire.

You can tell the alignment shop to compensate for that.
