Well I fitted these front and back on my 2004 HCH1 Hybrid Civic and it makes a tremendous difference. The insight central link posted above is where i posted the details and pics.
I used stock drag reduction spring clips on the front (They were missing on my car) and the Raybestos aftermarket ones on the rear. (We have discs all round over here in UK) What a difference
rolls very easily.
Now I know my car is a UK spec with A123 lithium fitted and manual IMA control but i'm doing 120mpg (imp) in the civic now. The clips have probably added +5-10mpg with my driving style.
Heartily recommended as a no brainer for every vehicle.
