Ok so we installed tanabe coupe springs specs r 1.7 in front and 1.3 rear, on a 2004 sedan with sedan sports shocks, and my question is why did the rear lower more than the front if coupe springs on a sedan is a higher drop and also does it matter if we have sports shocks instead of oem, would that cause a difference. It's not what we were expecting in the front drop Please help. Thanks!!!

 

You have to give the springs time to settle, but im in the same boat.

I just installed coupe Tanabe nf210 ( 1.1f .6r) on my sedan lastnight.
My front sits the same height as the OEM z springs i had before and the rear dropped about .5" from the OEM coupe rear springs i had. I have about a 3 finger gap up front and no gap in the rear. Im going to put some miles on them to see if the front settles,otherwise im going back to my old set-up and selling these.
