The attached pic. shows a Stillen rear steer lock up assembly

 

This is used to disable the Hicas system, assuming I guess the owner does not like Hicas or the rack is knackerd then Stillen have the answer...or do they.

 

Why use the original arm sections? this is the main area that wear takes place and this zed was no exception with excessive movement in the arm knuckles under the rubber boots bit of a swiz I think.

i fink it is to get rid of the 4 wheel steer .. not a wearable issue ... the racers apparently dont like 4ws , so remove , save weight ... think the weight issue is BS going by the weight of the Z anyways... cannot tel the diff between the 2 when driving my mates NA, obviously the cars r different but it dosent make u say wow the 4ws steer is excellent/crap if u catch my drift
