Lowering Civic Si 2004

Hey, on my new civic si, how do i lower just 1 inch. Can i lower it just with springs like eibach's pro kit, or do i need to get new coilovers too. I'm not good when it comes to suspension, so someone please explain. Thanks.

yes, you can use just eibach springs, and being an SI, the factory shocks will probably be able to handle a 1" drop.

The lowering spring set is the way to go. If you look at our suspension page you can find more information about how these affect handling and ride quality as well. I'd look at the Eibach Pro-Kit as the best setup if you want a minimal drop and improved handling:
