Check the driveshafts, you'll have witness marks on them as per my old setup...Bear in mind this was with adjustable drop links as well, the only way I found to fix this was to buy and fit an aftermarket roll bar
Up to 40 MM. is fine past 40 you get rubbing on drivers side drive shaft I have same problem all I done was baught adjustable anti roll bar links and problem was solved
Yer do get spacers I have 5mm isn't a lot but where mineis sitting low the passenger wheel/tyre rubs in the adjuster ring apparently it's quite common
