Any word on the Dive Planes? Mine's due a service and I'm keen to fit them if they work.
They were fitted to the AeroSS after the American Top Gear program criticised the car for its high speed stability. Early cars do not have them an no Aeromaxs would have had them from new.
I have them fitted to my car but can't say I've ever found the car to be unstable at speed; therefore, I'm not sure I'd notice the difference.
