    old settings

    FRONT

  • Camber: Range: -1.0 to 0.0 / Optimal: -0.5
  • Caster: Range: 4.6 to 5.6 / Optimal: 5.1
  • Cross Camber: Range: -0.5 to 0.5 / Optimal: 0.0
  • Cross Caster: Range: -0.5 to 0.5 / Optimal: 0.0
  • Sum Toe: Range: 0.0 to 0.4 / Optimal: 0.2
  • Toe: Range: 0.0 to 0.2 / Optimal: 0.1

    REAR

  • Camber FE1: Range: -0.6 to -1.4 / Optimal: -1.0
  • Camber FE3: Range: -1.0 to -1.8 / Optimal: -1.4
  • Cross Camber: Range: -0.75 to 0.75 / Optimal: 0.0
  • Sum Toe: Range: 0.0 to 0.40 / Optimal: 0.2
  • Toe FE1: Range: -0.05 to 0.24 / Optimal: 0.12
  • Toe FE3: Range: 0.0 to 0.24 / Optimal: 0.12
  • Trust Angle: Range: -0.15 to 0.15 / Optimal: 0.0 Note no FE4 entries... but they shouldn't be *too* far from the above. Based on the above ranges, what works well on my Z06, and looking up what M5 guys are running, i cobbled together some recommendations (haven't tried these... just MHO):

    Track Front:

  • -2.2 degrees negative Camber (if you can get that much)
  • As much Positive caster as you can get without sacrificing camber.
  • Neutral (0) Toe to 1/16" Toe OUT Each, 1/8" Total Max. [1/16" Toe out = -0.06 deg]

    Track Rear:

  • -2.2 degrees Negative Camber (if you can get that much)
  • 1/8" Toe IN Each, 1/4" Total Toe IN [1/8" Toe in = +0.12 deg]
  • Rear Toe should never be Toe out (negative)

    Aggressive Street Front:

  • -1.0 degrees negative Camber
  • As much Positive caster as you can get without sacrificing camber.
  • Neutral (0) Toe to 1/32" Toe IN Each, 1/16" Total Max. [1/32" Toe in = +0.03 deg]

    Aggressive Street Rear:

  • -1.5 degrees Negative Camber
  • 1/8" Toe IN Each, 1/4" Total Toe IN [1/8" Toe in = +0.12 deg]
  • Rear Toe should never be Toe out (negative)
