If you are looking for a quality carbon fiber wing blade, the Vorsteiner quality is next to none. We have tested this wing in house on our customer risers to speeds far exceeding normal street driving. Risers do not come with this product, this is for the wing blade only. We have tested this product with the NR or eBay style risers with positive results. 

The NR and eBay style wing blades we see quite a lot of movement around 70mph, after changing to the Vorsteiner wing blade we have tested the wing to 130mph speeds with out issues. 

*** Vorsteiner may discontinue product, so quantities may be limited, or non existent, stock will be checked upon placement order and refunded if no longer available
