It's not ideal no....however i'm sure if you send the rears back they'll put some longer rods in for you if you explain what's happening. Plus when i had the turrets done they didn't use the new coilovers for measurements assuming they'd be the same as the koni's i had on there so my turrets are a bit higher than standard. With the longer rods it may well be enough to cure the problem and give you the adjustment you need. If your bump and rebound settings are on the softest it will also enhance the problem, i found winding them up halfway has helped. Have you done anyhing to strengthen the rear turrets at alll??
