No, I don't run a VBC car. I run the Reflex Racing RR12 V2 with Xenon frontend. I thought I would try the VBC Ti coated kingpins because they would be easy to make spring changes just by unscrewing the end off. But I found that the VBC pins have a weird texture which causes them to bind up easy. Not as silky smooth as the Xenon Ti coated kingpins. It was just an experiment.
