These Front Lower Control Arms are designed for the 1996-2000 Civic. CA-EK-FL are engineered to provide the strength and performance demanded by racing enthusiasts while maintaining the same arm to rotor clearance as OEM arms. 
With the ball joint angle correction, the control arms improve suspension travel by keeping the upper arm in a more centered OEM location, resulting in improved clearance and more travel. This design increases the positive caster up to 2 degrees, allowing for less negative camber and eliminates the need for traction bars. The spherical stay true and centered, holding precise alignments, and eliminating suspension deflection and geometry changes under load seen with rubber or urethane bushings. 
The Pro Car Innovations Front Lower Control Arms are lightweight, weighing only 3.2lbs compared to the 6lbs stock. They come with M10X1.25 threaded sway bar holes for aftermarket sway bars using spherical end links, while still allowing the use of OEM sway bar mounting locations.

Please note that these control arms are not compatible with the one-piece EM1 SI arms or shock fork.
