Chassis: ZN6 / ZC6
The GT86 DF1800 + DF2000 kits are part of the Big Country Labs Downforce Division — where we get technical about moving air.
We took the BCL GT wing formula and went back to the air. The new DF profile was CFD-developed around making downforce efficiently, controlling drag, and keeping the size, stance and attitude you expect from a BCL wing.
AND IT MAKES DOWNFORCE.
At just 100 mph / 161 km/h, CFD simulation showed up to:
DF1800 — 267 lb / 121 kg of downforce
DF2000 — 344 lb / 156 kg of downforce
Figures shown at 12° wing angle.
The DF1800 and DF2000 were developed and analyzed across multiple wing angles, with downforce, drag, aerodynamic efficiency, endplate configuration and yaw performance all part of the CFD development process.
