Here is the Whiteline Rear Upper Outer Control Arm Bushing Kit for the 1987 Mazda RX-7 Base 2+2, LX, LX 2+2, Sport. The part number is KCA379. The listing names the Base 2+2, LX, LX 2+2, and Sport trims. The chassis code on the listing is FC. Application note: To hub adds +/- 1.5 degrees Camber. This part is for the rear of the vehicle. In the box: 4 bushings and 2 tubes.
Most factory control arm bushings are centered and fixed. An offset one is built so the arm sits at a slightly different angle, which changes camber, and the firmer material stops that setting drifting under load.
Installation is rated moderate, with about 2 hours of work listed. 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, Front Control Arm Lower Inner Front Bushing, and Tie Rod Boot Kit.
