Fitted mine 10 days ago
Fitted switch but left cable under rear seat, (switch fits perfectly in the cutout around the sender
Left in Sport.
There is a drivabilty difference, hard cornering pulls around a lot cleaner with less understeer drag.
Taking off hard front tyre rotation is at a minimum compared to standard.
One thing, my kit didnt come with the cone washer so I initially left it off (pix show it is supplied)
I removed and fitted the old one. Hope that was right?
