my car has been fully poly bushed including the dogbone mount with super pro bushes. Been this way for a year now and the car is done power wise at 300hp which I'm happy with. This was too much on the superpro dogbone bush and decided to change for the diesel mkIV golf version. Firstly the difference in size surprised me and after fitting it's made a hell of a difference! If you haven't done this yet do it!!!
