For 10,5T I think the new Mohawk Body of black-art is the 'one to get'. I've tested this body many times back to back, and at the twisty track of Mach Heemstede, or the High Grip, flowing Sipotech or Schermbeck track's it's just fastest. It's also the body with the highest down force, of all in the list ;-)
