I'm okay with everything except the open duct at the rear.It violates the 2 1/2-degree diffuser divergence rule,as reported by Hucho.I had this on the CRX at Bonneville,and ended up taping the whole thing shut with cardboard and racer's tape.Stylistically,its attractive,however its just that,styling.Aerodynamically,they're better off lowering the valance down to the appropriate elevation.
