I'm using two stock MCs to create a twin set up. Its easily done. Only fiddly bit compared to the fancy aftermarket ones, in some cases at least, is the addition of the pushrod and clevis assembly. On a micra as such its on the servo instead
Ah were not alot such gadgets with it being a competition car. All changes have to be made when static. Which is a tad unfair considering rally is the time you'd need it for surface changes.
I hope you venture along with the car to an event so we can compare notes
