I've had one one for over three weeks now and it's still on good! I recommend that you get some plastic washers for use between the spoiler and the shafts PLUS plastic washers for INSIDE the spoiler also just in case. I was a little unsure how much to torque down on fiberglass but this seemed to relieve me of that uncertainty. My MPG has not changed... oh wait... I'm getting 99MPG now!

Hehe...
