It definitely made a difference. There is now no more "delay" on the 1-2 gear change where before it felt like i'm smashing the synchros when trying to shift quickly. 2-3 gear change is also much faster and smoother.
Cost to install = 1hr all up of my time as I did it at home (I swear 45min of the hour is getting the car jacked up)
