Can anyone tell me why Eibachs on a 350Z lowers the rear more so than on the G35 coupe? The Eibachs on a 350Z lowers it rear perfectly, just enough to tuck the wheel a bit. The Eibachs on a G35 Coupe doesn't even come close. Anybody know why? Also, does anybody know of a spring in the rear that tucks the rear or at least come close on the Coupe?

 

my eibachs make my car sit right above my tires. i can fit only my finger between the tire and the fender. Did you just get em put on? Wait for a little while and they will lower a bit more.

 

When you have soft spring rates [once corrected for motion angles and trigometric attachment points] a 10% ERROR is stiffness per inch translates to a 35% difference in ride height.

I always wonder whether people are measuring with their body weight in seat or unloaded..............100 pounds [140 >240 driver] can lower the body roughly 0.4-0.5".
Full or empty gas tank, passengers or no passengers.

Just like alignments must be done with the weight as you drive the car so must spring adjustments.
