Any one knows where I can buy Coilovers and roof spoilers for 2012 accord? and websites?

I just bought new Rims for accord, it was 16'' but just got 18'' and my car looks like a tank now.

I dont wanna lower it too low but want to lower it maybe 1-2inches. Is it better to go with coilovers or Springs?

/Also on a buget plus either one I buy have to pay someone to install it too.

Heres a picture of my car.





Thank you for your time to respond!!! Have a good one
