I don't know if anyone else has found this to be a problem, but ever since I've had my Z I've always found the footrest to be a bit too far away. Now that may be because I'm somewhat short in the leg, but nevertherless I have now done something about it.
I simply removed the 5 screws and ally cover, marked around it onto a piece of 4x2 soft wood, cut it out with the jigsaw, painted it black so it wouldn't stand out like a bulldog's b*llo* and refitted it to the car using longer self tapping screws. Hey presto a footrest I can now comfortably reach. Blue Peter would be proud of me.
