Corvette Rear Toe-In

  1. To adjust rear wheel toe-in angle add various thicknesses of shims (1/64", 1/32", 1/8", 1/4") between torque control arm and frame side member at forward pivoting point.
  2. Shims are slotted to slide over bushing pivot bolt on either side. To adjust, loosen pivot bolt and position torque control arm to obtain specified toe-in. Shim the gap between torque control arm bushing and frame side inner wall. See  Fig 1 . 
    NOTE: Do not use thicker shims than necessary. Do not use excessive force when shimming or toe-in setting may change.
  3. Shim outboard gap as necessary to obtain solid stack-up. Then install cotter pin through shims. See  Fig 1 .  Tighten pivot bolt to 50 ft. lbs.
