I don't mean to sound impertinent but who follows a gravel truck at 100 MPH?
If the rock is from someone in front of you, then you are too damm close.
If it is coming from opposing traffic then we are talking a higher than 100MPH strike.
My NA went 150 MPH in Arkansas on roads that were in awful conditions. No rock chips. Guess I was lucky.
Mike in Orange is correct, the paint on our Crossfires would not be the same as the "cheap" stuff they use in the American plants. Europe requires different formulations for
environmental reasons. Trust me, it wasn't formulated for performance and it wasn't "cheap."
It's like sex,(isn't it always?) Abstinance is the only sure method of prevention. If you don't want rock chips, don't take it out of the garage.
