I'd like to lower my car. Which springs do you suggest?

[summit425]

hi guys

summer is coming and I'd like to lower my car a bit.

Currently I have a stock suspension but I'd like to just add new springs to it.

I do not like a bumpy ride so it would be great if you can suggest me a set of spring without losing too much comforness of stock suspension.

here is my car right now.
My rear is much higher than the front.. is this normal??
