Nine Lives medium down-force kit for NB Miata. Are you looking to win? Well good your in the right place. An all-in-one aerodynamic kit, just bolt it on and know a team of motorsports engineers has set up your personal car. A package that has seen 3 seconds a lap improvement on cars with only a 100 hp.  All of this for less than a traditional carbon wing.   

  • Stock powered cars (100hp) have dropped 3 seconds a lap. 
  • Fully CFD verified 
  • Weight  and Aero loads in perfect balance
  • Minimum drag 
  • Comes with set up notes from Morlind Engineering. 
  • Upgrade-able to high downforce kit. 
  • Engineered sized splitter 
  • Damn Dam air-dam 
  • 64" Miata Wáng kit
  • Sturdy Boii Splitter mounts and radiator ducting  

Upgrade / Add-ons Splitter material. 

  • Poly infused birch, a cost-effective splitter that will with-stand the elements. 
  • Tegris, just like a very popular racing series that only turns left uses. Tegris is a woven plastic splitter that makes very little drag when it slides on the ground. It also resembles a carbon fiber look with 1/2 the price.  
  • 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?




Warranty/ Returns/Lead times

All items are built to order. Please allow 2.5 - 3 weeks for production components, and 6 - 8 weeks for pre-orders and custom items. Uprights that are not built by 9LR will ship directly from manufacturer. 

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 Bois, 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. 

* Open air testing numbers available at https://9livesracing.com/cfd-testing

Custom orders are built to the customer's specifications and Nine Lives Racing will not be held liable for any malfunctions. It is up to the customer to verify operation is safe.
