Product Details
The Whiteline Front Lower Inner Rear Control Arm Bushing Kit fits the 1989 Mazda RX-7 GTUs (FC). The kit contains 2 bushings. Placement: front. The part number is KCA380. Application note: Suits series IV models: adds .0 degrees Caster. Trim named on the listing: GTUs.
This kit does more than replace rubber. Its offset design moves the pivot point of the lower control arm to add positive caster and change how the front end resists dive under braking, which improves straight-line stability and turn-in feel.
Whiteline rates the install as moderate and lists about 2.5 hours. Get the car aligned once it is back on the ground. To go with it on the RX-7, see 12mm Adjustable Front Camber Bolts, Tie Rod Boot Kit, and Rear Upper Outer Control Arm Bushing Kit.
