Just lowered my car with tanabes nf210s, on an 07 we had to adjust the strut bar to fit back in place, j/w if thats normal im sure it is as it affects the body flex and suspension....just asking becuase my friend who helped with the install did not have to with his Z and used the same springs for the drop. Thanks again

 

Yes it is normal.

 

i experienced the same....nothing unusual.....
