They're a good buy. I was never going to just keep braking standards, after a good few miles now vibration although increased is perfectly acceptable to me, bit harsh on first cold start but soon improves. Gear box feels very good, power delivery is smoother and the car feels much much more solid. Vibratechnics are doing some diesel tuning this year so I dare say a diesel specific item may not be far away. I bought now as the gearbox mount was utterly dead! I also have the superpro diesel dogbone bush, any increased vibration I get could be my smf, its all about personal tolerance.
