Sizes: see table below
- Canards are small winglets on the front bumper corners used to fine-tune front aero balance. They sit in the splitter's upwash and their tip vortex keeps flow attached at high angles (HPA).
- Unlike a splitter they get no ground effect, so they make less load per area and more drag, but they are much less ride-height sensitive (HPA).
- More canard load generally hurts the rear: the upwash feeds dirty, low-energy air to the rear wing and reduces its effective angle (HPA).
- The file is a reference example built by Xem Studio from the numbers above (18.4 deg = atan(100/300) from HPA's rise ratio; width illustrative.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.

parameter  value or range  source
Leading-edge alignment  about 5 deg nose-down (to meet splitter upwash)  HPA canards
Profile rise (ballpark)  ~100 mm rise per 300 mm length  HPA canards
Starting height  ~250 mm above splitter at lowest point  HPA canards
Outer flick / endplate  ~20 mm tall, top surface only  HPA canards
