Don't get excited just yet...You're jumping the gun on assuming you have a problem....Those ESPO springs are highly arched and you have no weight on them... The arch of the front segment alone will pull the axle forward from the center of your wheel opening...If you lower the car with just a shell it's not going to be at it's final resting position and you may not even get the rear shackles to go back{over center} to the correct orientation without some help as you lower it...This is normal with a high arch spring...

The more components{weight} you add to the car the "flatter" the front segment will get pushing the axle back to an acceptable position...
