I was wondering what brand of lowering springs are good because I'm trying to lower my car.

I have a Honda Civic LXS Sedan 2010

I highly recommend eibach springs.

Eibach or Tein

are they a lot better then tien and skunk 2 because those were the ones i was looking at

Skunk 2 is no good. Go with eibach or tein. They are about the same as far as quality goes.

will they last a long time because i know i will be taking them off for winter and stuff

Yes. They will last a very long time.

thanks for your help.. do you know any website for civic besides procivic.com because that's i use a lot

I personally use ebay quite a lot. You can surf through and find the lowest price.
