Rear Lower Control Arm Relocation Brackets for 2005-2014 Mustangs. Also called Anti-Squat Brackets, these brackets move the instant center location upwards and rearwards to increase the anti-squat percentage, therefore increasing traction.

  • Compensates for the loss in anti-squat, caused by lowering your Mustang, by adjusting the rear suspension geometry.
  • Allows increasing anti-squat to far above the stock percentage.
  • Multiple control arm mounting holes allow tuning anti-squat percentage for the optimum launch.
  • Extremely stiff. Comparison testing showed these MM brackets to have less deflection under load than any competing bracket.
  • Less deflection means better launch consistency and better handling.
  • Allows use of stock-style rear swaybar and stock rear lower control arms, unlike many competing brackets.
  • Reduces roll understeer for improved handling on lowered cars.
  • Improves ride quality by adjusting the suspension geometry so that the rear tires move rearwards when striking a bump, instead of moving forwards.

Better by Design

MM's Engineering Team load tested these brackets, as well as brackets from other manufacturers. The claimed superiority of weld-on brackets over bolted-on brackets was quickly disproved by testing. It is the design of the bracket that ensures strength, not the method of attachment. All other relocation brackets started deflecting at much lower load levels (power levels) than the MM-designed relocation bracket. Load testing is just one of the ways we confirmed that our design was not only stronger than others, but is also up to the challenge presented by a high-powered Mustang.

  • Improves traction, both at corner exit and in a straight line.
  • Multiple lower control arm mounting holes allow tuning the anti-squat percentage for the optimum launch.
  • Designed by MM's engineering team to be very stiff. Less deflection under load leads to more consistent launching and handling.
  • Bolts-on; no welding required
  • Multiple mounting holes for the lower control arm allow tuning the instant center location for optimum launch characteristics.
  • Very stiff, allowing little deflection under load.
  • Maintains stock Panhard rod location
  • Clears stock swaybar
  • Clears direct-replacement aftermarket swaybars
  • Compatible with stock and direct replacement lower control arms
  • Bolts-on; no welding required
  • Includes hardware
  • Durable black powder coated finish

How do I choose which hole to mount the control arm to?

See the procedure detailed in the Mm5RLCA-57 installation instructions.

What is "instant center"?

Instant Center (IC) is the location in space, when viewed from the side, about which the rear suspension rotates around as it moves up and down. In the case of the S197 Mustang, it is determined by the geometry of the UCA and the RLCA pivot locations. The IC location needs to be determined in order to calculate the amount of anti-squat geometry that the rear suspension has.

What is "anti-squat percentage"?

Anti-squat percentage (AS%) is the fraction of anti-squat behavior that the rear suspension geometry has relative to full AS (100%). In a rear suspension with 100% AS, none of the forward acceleration forces pass through the springs or shocks, so the ride rear height does not change during acceleration. In a rear suspension with 50% AS, half of the acceleration forces pass through the springs and shocks, while half of the forces pass through the centerline of the control arms.

How does the anti-squat percentage affect launching?

With 100% AS, any longitudinal (front to rear) weight transfer happens nearly instantly during launch. With 50% AS, half of the acceleration forces during launch pass through the centerline of the control arms, and half of the forces go through the springs and shocks. The springs and shocks take time to change length. While they are changing length, they can't conduct the acceleration forces to the rear tires; only after they stop changing length can they conduct the acceleration forces. Since the acceleration forces are delayed in reaching the rear tires, there is less rear tire traction available for acceleration during the suspension motion. This is the main reason why 100% AS geometry gives the most forward rear tire traction.
