Removing that would be the equivalent of dropping 340 lbs or adding 34 hp!

The first thing I'm going to do is to swap out tires. I am sure it will make a huge difference.

Yikes. Very interesting. That scares me knowing I am running BMW wheels Style 215 wheels that are heavy and run-flats. 85lbs for the rears!

Would you share the math so I can figure out how big of an anchor I am dragging.
