1997, 1999-2000 SUSPENSION
Rear - Miata
DESCRIPTION
Rear suspension consists of spring over shock, crossmember, upper and lower arms, and stabilizer bar with
control link. Upper and lower arms attach to crossmember and knuckle. A stabilizer bar with control link is
mounted to lower arm and crossmember. Rear wheel alignment is adjusted by turning adjusting cams on lower
arm. Upper coil over shock mount plate has been redesigned for 1999-2000. New design incorporates a
urethane bumper and improves ride and cornering.
