Good discussion on Insight central about reducing drag from discs brakes with spring clips.http://www.insightcentral.net/forums/ot ... ction.html
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 spring clips on the front (They were missing on my car) and the Raybestos aftermarket ones on the rear. 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.
No brainer for every car IMHO.
