  • Fully CFD verified 
  • Weight  and Aero loads in perfect balance
  • Minimum drag  
  • Upgrade-able to high downforce kit.

  • Poly infused birch, a cost-effective splitter that will with-stand the elements.

  • Carbon, you're mad if you want this. Yes, it's light, but it's expensive as all get out. You really wanna smash this thing?



2005-2015 Miata Splitter mounts! Thank you Trackable Miatas Facebook group for giving it the name of Sturdy Bois.

Splitters are a flat surface attached to the front of the car. This part increases air speed under the car, resulting in extra front downforce. in the past mounting a splitter was a time-consuming fabrication project. We are happy to announce adding a splitter is easy with Sturdi Boi Splitter Mounts from Nine Lives Racing. Sturdy Boi Splitter Mounts are brackets for you to attach your splitter. These mounts attach to factory bolt holes and offer a quick disconnect feature for easy trailer loading. The mounts are solid to capture air and force it into your radiator. Will keep your car cooler for longer and increase downforce.

-Words from a race engineer. "To make a car lighter you must make every part do as many jobs as it can."

Warranty/ Returns/Lead times

Powder coat or vinyl "wang skin" upgrades are strongly recommended. Otherwise, wings are shipped raw, and while aluminum does not corrode the same way ferrous metals do, your wing will get progressively uglier as it is exposed to the elements.

Wangs and Mega Wings are covered by Wang Guarantee.  Splitters, Sturdy Boiis, and air dams, based upon the nature of the use (and proximity to the earth), carry no warranty and are non-refundable. If you bolt these items to the car you own 'em.
