thanks everyone, very helpful. I'm swayed by Neth and I think I will go with the race mount when the car is going in for its 5 year service. I don't mind the vibration at idle and I think increased stiffness suits the car.
Engine mounts have received slight design update. A bit more taper for easier installation and cosmetic changes for refined look. We added CNC phase for shiny finish of the housing and laser etched logo. Pressing adapter now also available as an option.
