Virtual Wind Tunnel: Broken Wing

I broke the rear wing of my real Kyosho Mini-Z MR03 Mazda 787b last night while racing at Haagring. So I decided, just for fun, to run a CFD "virtual wind tunnel" simulation of a broken rear wing.

The results were the following: the drag force recorded by the simulation while the car was "racing" at 10 m/s (36 km/h) was 6.4 gf. The down force recorded by the simulation at this speed was - 3.8 gf, that is, 3.8 gf of lift. 
No significant lateral forces were measured, in spite of the asymmetric wing configuration.

The pictures below show the pressure coefficient (Cp) indicating high (red) and low (blue) pressure areas.
