Stud boys with plastic backers

[Notenoughtoys]

Anybody else run those stud boy studs with plastic backers? Bought my wife's viper that already had them on it. Not very impressed with them. Already found some loose. The backers are plastic with plastic threads???? Really? Gonna swap these out next year for sure!

do you have pics of the backers? if they are the ones that replace regular aluminum washers and still require nuts, only had luck with them on a fan cooled 550, had some on a RX1 for one ride but, broke 5-6 of them and pulled the all off and installed aluminum ones. they made for cool washers for the race bike tho. the tall ones that don't need nuts seem to be holding out good on my buddy's IQ600RR (he uses the double ones....with 1 7/8" studs) on his 1 3/4" track
