MM News

Mythbusters! Watch the July 31 episode for Mustang mayhem. We're big fans of the show, so we were happy to oblige when the producers asked us for an MM part to help Adam and Jamie attempt to bust a myth. See if you can spot the MM part in the new Summer Season Sneak Preview and the Winter Season Sneak Preview. More Mythbusters is on the MM Facebook page.

MM on TV is now on the web! Watch Engine Power on the web to see the installation of a Maximum Motorsports suspension package on Engine Power's "Barely Legal Mustang" project car. This Fox Mustang also gets a Coyote engine swap! Engine Power is one of the Power Nation TV shows airing on Spike, CBS Sports Network, and NBC Sports Network.

Vortech's 2014 Mustang SEMA show car, with its MM suspension, is on the road, traveling from show to show. It will be on display at the Fresh Meet Summer Bash at Kean University in Union, NJ, July 13. The next event will be Mustang Week, at the Myrtle Beach Mall in Myrtle Beach, SC, July 18-19.

MM's Road & Track Box for 2005-2014 Mustangs is now available. StangTV has an installation article, and a press release. Read more about MM's latest Grip Box on the MM website.

Maximum Motorsports Heavy-Duty series Rear Lower Control Arms for the 1999-2004 Mustang improve traction and handling by reducing the unwanted deflection allowed by the stock soft rubber bushings and flexible stamped steel control arm. Unique MM 3-piece bushing and spherical bearing design easily allows the articulation required for proper handling, and reduces the deflection that can cause wheel hop.

Fits 1999-2004 Mustang with solid rear axle. Includes spring perch and swaybar mount.

If your Mustang...

Why not use the Heavy-Duty control arms in those situations?
For one reason: Those situations may overload the urethane, leading to premature failure of the bushing. When you hit your Mustang's throttle pedal, all of the forces accelerating your car pass from the rear axle housing through the lower control arms and their bushings; that's what moves your Mustang forward. The harder the car accelerates on launch, the greater the forces on the lower control arm bushings. Higher forces lead to a shorter lifespan of the bushings.

Better by design

  • Stress on the chassis torque-boxes is greatly reduced because the MM design allows proper articulation of the rear suspension.
  • 3-piece urethane bushings allow articulation while reducing deflection and damping noise transmission at the chassis end.
  • Spherical bearing allows articulation while eliminating deflection at the axle end.
  • Large 2" diameter round steel tube design for highest strength.

Why do I need MM Rear Lower Control Arms?

  • The stock Mustang rear lower control arms are fitted with very large, soft rubber bushings. Those bushings allow the axle to shift fore and aft, causing the toe of the rear tires to change. Toe changes cause instability as the rear of the car steers itself in unpredictable directions. The rubber bushings also allow axle wind-up during acceleration, which in turn causes wheel hop.
  • MM Rear Lower Control Arms were designed by our engineering team to minimize fore/aft movement of the axle, while also retaining the suspension's ability to properly articulate. This improves performance without unnecessarily compromising ride quality or handling.
  • Potential torque-box damage is greatly reduced because the MM design allows the suspension to easily articulate.
  • Manufactured by MM in the USA

Fits

  • 1999-2004 Mustang with a solid axle

Do NOT fit

  • 1979-1998 Mustang with a solid axle because of the different mounting bolt size used during those earlier model years.
  • Fox chassis Fairmont, Zephyr, LTD, and Marquis
  • Fox chassis Thunderbird
  • Fox chassis Lincoln Mark VII

Q: Can I use the MMRLCA-5 in a drag racing application?
A: Yes, but; the heavier the car, and/or the harder it accelerates, the more quickly the urethane bushings will wear out. How quickly the bushings wear depends on the overall weight of the car and the magnitude of the acceleration off of the line (60' time). For cars over 3,200 lb and/or 60' times under 1.7 seconds, we strongly recommend our Extreme-Duty Rear Lower Control Arms.
