lowering... do or dont?

first off, the post is misleading. im not asking if i should lower my car. but hopefully you know about lowering if you are reading this and you can help me out.

i have dropzone coil overs on my civic. the front and back were both lowered 2.5". yesterday, me and my friend got bored and decided to slam my ride. we dropped the back all 4" and we left the front alone (cuz it naturally sits/looks lower). the car looks awesome but i was just curious if there is any risk in having 2 different measurements. it's only been driven like this for one day.

so it's 2.5" in the front and 4" in the back...any help/advice would be helpful! :D

there will be slightly more wear , but nothing noticable..
but if the back is 1 1/2 inches lower it would look stupid..
not to mention you'll kill it if you drive it anywhere but flat..

well it actually looks pretty good. you cant really tell they are diff until you look at the wheels closely. i was just worried bout damaging the car. im getting new tires in a week so i'm not too worried about tread. im picking the back up to 2.5" again on new wheels tho. more posts would be nice... ;]
