It can't touch at all! I swapped the arms side to side, the rod ends can't be swapped tho, then ground the knob off the track rod end which pokes down, then a little bit of tweaking to get the lock bolt to clear. I presume different kits will vary slightly so if its not quite as high it may be a bit easier! Don't forget camber bolts cos it screws it right up and they're scary to drive in the wet until you do them!
Been thinking about this most of the morning, what implications does modding the hole and track rod ends have on the MOT?
