Our version 2 chassis mounted splitter is a balance between track and show cars looking for something more durable than a bumper mounted lip, and provides actual downforce. We have designed a system that allows for blade AOA adjustment with the splitter on the car. The endplates are optional, if you prefer a cleaner look.
For a baseline reference - at 0 AOA the blade itself produced 50lbs of downforce at 100mph based on CFD simulation. On track testing on similar platforms has shown that increasing the AOA and/or adding additional Aero elements (end plates, splitter diffusers (tunnels), fender spats, canards, hood vents etc) improve the efficiency significantly.
We also offer this bracket kit, without a blade if you would like to make your own splitter blade. Email support@cjmind.com
