are you sure you didnt get the sedan kit?... that could be why its sitting higher.

The coupe part number is: TSC063

Sedan is: TSC130

 

the sedan version has helper springs both front and back?
mine only have it up front. well not anymore since i took them off but...

 

only the front have helper springs...

I'm thinking you installed sedan kit... I have them and I'm sitting as low or lower lower than you are in the rear and still plenty more adjustment to go lower... if you are on sedan coilovers, you arent going as low as you could with coupe kit.

here's a pic of mine (this is even before springs settled):

 

Interesting..

sacpbyee, do you have the box they came in? Or is there a designation number on the coilovers themselves?

 

Hi guys i have the same coilovers for my 2003 g35 coupe and it's not as low as i thought they would be. i took out the smaller lock ring in the rear and it's still not that low. i'm pretty sure i installed them correctly too.
