Yea, I did mine last summer 'cause they stopped working. Good write up!!! My only .02 cents is this... When you think that you have it all adjusted right by how much drag you get from the free spinning tire, you need to go do a 20 mph e-brake stop in your street (making sure your thumb is holding down on the button). This is what I did to test the setup, and I'm glad I did. Thing was still only working on one side even though the spin test said it was good. the stop test said it was, FAIL! Tried to go sideways on me!!! When Oh-Shit happens, you can count on the worst when you pull that fucker and the car goes sideways... Just make sure that after you get everything adjusted all nice, you keep at adjusting the offending side till both tires are leaving the same amount of rubber on the road and the car is stopping its self straight...

Most important!!!
