I'm thinking you've got a particular look going on with your car; mostly painted...either black or red, even your grill insert is painted red.
I've always thought that the red hairpins were kind of unique.
I know others have said chrome hairpins will match the chrome wheel covers, but my opinion is that if you go to chrome you're going to lose some of that character the car currently has...seems like everybody has chrome hairpins...my vote is go with something different than the rest of us...stick with the red ones.
