Thanks for the input. I did alot of research prior to installation and found many folks on both sides of the fence in regards to the shields.Some had problems and many had no problems what so ever.

My wife is the primary driver, she is very easy on the car, very non aggressive driver on very flat surfaces here in Florida. I found most drivers who had problems were in areas with hills and mountains and who were somewhat aggressive in their driving modes. I know these may seem like generalizations but those pretty much sum up my findings.

Are your findings from personal experience or just from other folks who have used these items?
