Plus Points
Considerably reduces engine movement under all conditions
Car feels tighter
May lead to reduced wheelspin and better control as transition from decel to accel can be made smoother.
Reduced wheel hop /axle tramp type vibrations
Fabulous cost/benefit ratio
Can easily be reversed if reqd
Vastly improves the clutch judder I used to have at the biting point
Minus Points
Does increase the level of vibration felt through pedals/handbrake , although this is very minimal.
For me its not even a consideration.
Summary
This is how it should have come from the factory : GET ONE :
