Wheel balancing is amazing...

About 6 months ago I replaced failing control arms associated bushings, tie rods, and swaybar links. Then last month I got rid of my vibrating metal-torn drive shaft, and associated torn center bearing. Just today, after having had my tires on for 7 months, I went and got them rebalanced. Just, WOW.
For the past year my car has ever so subtly tapped me on the shoulder (read: Shaken my ass) to remind me that we had reached around 80 mph. There were also subtle hints, starting at 60 mph, just nothing that didn't feel like "an old car". This was the first time in years that I had all those parts in good order, and boy was I surprised when I went to "scientifically test" the new balancing (read: floor it on a freeway on ramp) and low and behold, as if driving on clouds, I went through 90mph. It felt good :-)

Anecdotal story over.

I love it when a plan comes together
