the xr hubs sirt further out than the cossies ones, due to the longer driveshafts, so they also have a wider wheelbase

also cossie brakes wont fit on, unless you go the rs turbo route with cossie 2wd discs and 4wd calipers

only reason i went cossie hubs is for the cossie breaks to keep it all tied up with cossie everything else, but the ball joints are a nightmare to get on with the longer shafts
