8-9mm lower on one side...

Jack front up both sides, measure from somewhere fixed thats on both sides in wheelarch down to the lower drop link bolt,

if you suspect arb...just unbolt the drop links and then check

So this morning I jacked up the car and measured from the bottom drop link bolts to where the bottom of the wheel arch is (behind the wheel & shocks, the straight section couple of inches long, same on both sides)...both the same measurement...the difference in height seems to happen once the car is down on the ground and weight is on the suspension...had new springs and new rear beam already...but not changed the shocks... :\

Thanks again for the replies guys...hopefully will get to the bottom of this, then carry on with my mods so I can do my first FCS this year...
