Dežru Spec-S Coilover Suspension for 2002–2005 Honda Civic Si (EP3)
The 2002–2005 Honda Civic Si (EP3) carries Honda’s legacy of motorsport-inspired engineering — lightweight, rev-happy, and built for driving enthusiasts. But its factory suspension was tuned to please the masses, softening the edge of what is otherwise a brilliantly nimble FWD chassis.
The Dežru Spec-S coilover is the suspension the EP3 should have come with. Lowering the car by 25–30mm, it sharpens steering response, controls body movement, and frees the chassis from its watered-down stock setup — letting the Civic Si shine through corners with confidence.
