They make it work pretty well on trophy trucks.  |
Trophy trucks don't need a low CG like a Rally car does.
Rally suspension is designed to sit very low in the suspension's throw at static ride height. It's actually very much like a road suspension at static through max compression. However, if the car becomes airborn, the suspension has a *ton* of droop combined with a very low fast rebound damper, which allows it to drop quickly to be ready to provide a soft landing when jumping. See pic.
Of course there's also the chance that due to homoligation rules, rally teams are simply required by the factory to use the "inferior" MacPherson struts because the factory can't afford to put double a-arm suspension on the production car... But, considering how many things are build into the street Impreza just to make it a better WRC car, I would bet if there really was a big advantage to the double a-arm, that's what would be on the street car so they could use it in the WRC.
