Corvette Medium Downforce Kit ‘97-04 C5



Increase downforce by over 210% vs OEM!

Aerodynamics is a hard word to spell and even harder to do right! Don’t worry; a real aerodynamicist built this kit just for your C5 corvette. Any little change in parts throws your aero balance wildly into the weeds. I’ll bet you didn’t know there was such a thing as aero balance before reading this. THAT’S WHAT WE’RE TALKING ABOUT! ? We spent painstaking hours in CFD and at race tracks building and shaping all parts to work in perfect harmony to make you faster.

What’s the deal? Medium Vs high downforce kits.

The Medium Downforce Kit was built for the budget-minded racer that wants to buy an aero package and a set of grippy tires (this place reserved for Tire marketing opportunities). This kit was built to provide regional winning tech at the cost of other guys’ wings. This kit is great for the people that love to race but love even more just to be at the track.

The High Downforce Kit makes over 1000 lbs of balanced downforce and is meant for the driver who needs ultimate performance at the track. It’s perfect for the racers that want to win a Professional Championship.

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.
