Show original supplier description

Part #: YA0674

This complete set of helmet spoilers are designed for us in the Indy Car championship. These are manufactured to the exact specification as required in their technical regulations. These self-adhesive low profile spoilers are easily applied to your crash helmet and are a complete set with a full frontal selection as well as the top of the helmet. While the low profile shell of the ST5 alleviates most buffeting issues you could have, these spoilers will eradicate anything that you may be experiencing.
