I locked my gearstick in with a drill bit, but it seemed to be in the wrong place as it was nowhere near a neutral position and after adjusting the cables at the box end, I coudn't get gears 1,3 and 5.
I removed the drill and faffed a bit with the cables. Seems pretty good, although I was doing a bit of enthusiastic driving and it made 3rd and 5th a bit hard to select under braking and a bit of cornering. I was trying out my xds after switching onto the highest setting.
It transformed the car, a bit like a fwd rally car I used to have with a proper lsd fitted.
