back side lifting

Hello

I am with Honda CRV 2002. I want to raise litle bit the back side of my car. Now the space between the tire and mudguard is 2 fingers only.
Is this possible if I change only the springs?

now what is done to the car is it lowered because as soon as you start messing with ride height you need to know if alignment issues are gonna be affected.. because maybe shocks are shot and making rear end sag or maybe the previous owner lowered it but whatever you do you can just replace the springs with different or factory ones but after you do it have the alignment checked because hondas use four wheel alignments

All cars should have a four wheel alignment. Push down on the back of the car, if it bounces more than once, you need shocks. Replacing it with the OEM or equivalent should get it back to normal. CRVs arent excessively high to begin with.
