i have a 2013 x sedan lowered on swift springs but the front is too low compared to the rear so i'm looking into different springs since theres over an inch difference. There aren't many options for awd springs besides eibach but i would like to be lower. I was looking at Tein S springs but they only make them for a rwd model, I've seen other x sedans on these springs but i wanted to know if it would damage anything with my awd system.

I already have a front and rear spc camber kit

 

lol mine is the opposite... the rear is higher than the front.
RWD springs will work but i don't know if the drop will be even.

 

my rear is higher than the front too unless you mean lower? can you post pics of your car if you dont mind

 

My Eibach springs for the X are the opposite as well. My rear is perfect in my opinion and I'm running stock 18" wheels. I feel like when I put 20's on later down the line, there will be almost no gap. If I were you, I would look into getting Eibachs for the rear if it bugs you that much.

Edit: I just found a picture on my phone of an X on Eibachs and 20's and there's a bit of a gap.

 

If you want to go lower, just get coilovers. Springs are only good for minimal drops, mainly to close up the huge wheel gap.
