Finally got around to buying and fitting the rail. Ended up getting maximums to fit it as I was getting some other work done. Apparently it took a bit of messing around with and a couple of small mods were needed but the cost was minor and I know its been done properly.

It's definetly made an improvement to the seating position. Its not a huge drop in the seat height but would be a good 20mm. The first thing I noticed was the change in angle of my left leg in relation to the clutch pedal. Feels less like I'm driving a 4WD and more like a sports car. Feels like I'm sitting in the car now and not on it. The true test will be when I'm wearing a helmet though.
I forgot to take some photos before it was fitted but below are some pics of it fitted.





Some pics of the passenger side for comparison.
