This was my first modification to my 2001 viggen along with the rear 22mm RARB and the steering rack clamp and brace. Unlike some others, I did not notice any increased vibration at idle. From stop, there is no hesitation or "laziness" of the transmission that used to be there. Power is more ubrupt without the "thumping" feeling that used to be there. All gears smoother when getting on or off throttle...feels solid. Shifting is definitely smoother and easier throughout all gears. Worth every penny...it makes that big of a difference.
