MM News

MM in print: 5.0 Mustang & Super Fords magazine asked us to help with the Tech for an article titled "Full Plate," published in the new (June) issue. The article details the many differences in caster/camber plates required to cover the variations in Mustang strut towers from 1979-2014. Read it, and then impress your friends with your knowledge of camber plates and alignments.

MM-equipped racers won 3 classes at the 2013 NASA National Championships! MM congratulates the new National Champions: John Miksula in American Iron Extreme, Alec Udell in American Iron, and Aaron McSpaden in the Camaro-Mustang Challenge. MM thanks all of the racers who chose to equip their Mustangs with Maximum Motorsports parts. MM also congratulates MM-equipped racers Chris Griswold for his second place finish in AIX, John Yung for his third place AIX finish.

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 1979-89 Mustang Caster Camber Plates provide the means to properly align your Mustang's front tires. Especially well-suited for lowered Mustangs because MM's innovative design provides a much wider range of adjustment for camber than the stock adjustment slots.

Better by design

  • Maximum Motorsports invented the double-adjustable caster camber plate for Mustangs in 1993. That innovation pioneered the separate and independent adjustment of caster and camber for Mustangs.
  • Strong enough to support a coil-over conversion.

Why do I need MM caster camber plates?

  • Lowering your Mustang will cause the top of the front tires to "lean in" towards the center of the car (increased negative camber), resulting in uneven tire wear.
  • This excessive negative camber can be easily corrected with the Maximum Motorsports Caster Camber Plates, allowing alignment to factory specifications.
  • Lowering your Mustang also results in a reduction of bump travel, which will degrade ride quality. Installation of Maximum Motorsports Caster Camber plates restores most of the lost bump travel.
  • MM Caster Camber Plates provide the means to adjust the front alignment for improved performance.

Camber Adjustment
The wider range of camber adjustment allows the reduction of excessive negative camber caused by lowering. That will improve tire wear of a street-driven Mustang. Camber may be adjusted to a much more negative setting for more front grip when cornering.

Caster Adjustment
MM Caster Camber Plates provide adjustment of caster, which is otherwise not adjustable. Increasing the amount of positive caster improves straight-line stability. Increasing the amount of caster also helps increase front grip during cornering because additional cater causes an increase in negative camber on the outside tire when the car is steered into a corner. The increased negative camber increases cornering grip. The increase in negative camber is only present while the tire is steered, and therefore does not harm tire wear.

Construction

  • Main plate is laser-cut from high-grade alloy steel, not mild steel. The increased strength greatly reduces the possibility of bending.
  • MM-designed spherical bearing is custom made in the U.S.A.
  • Durable black powdercoat finish is standard.
  • Chrome finish on the main plate is optional.

Benefits

  • Provides the means to set the proper front alignment for your Mustang to have best performance and best tire wear.
  • Lowered Mustangs can be aligned to factory specifications.
  • Provides a wider range of camber adjustment than is allowed by the stock camber adjustment slots.
  • Negative camber may be increased for competition.
  • Provides caster adjustment (otherwise not adjustable).
  • Allows greatly increasing caster for improved straight-line stability and improved cornering ability.
  • Designed to support a coil-over conversion.
  • Allows increasing bump travel.
  • Double-adjustable. Both camber and caster can be adjusted independently; adjusting one does not affect the other adjustment.
  • Caster and camber are easily adjusted at the top of the strut tower.
  • Spherical bearing mount eliminates deflection and precisely locates the strut shaft, while still allowing the articulation required for steering and suspension movement.
  • Improves steering response and dynamic alignment stability by eliminating deflection allowed by the stock rubber-bushed upper strut mount.
  • Bolts on. No drilling or cutting required.

Maximum Motorsports Caster Camber Plates for 1979-89 Mustangs

Features

  • Separate and independent adjustment for camber and caster.
  • Widest possible range of camber adjustment, twice the range of the stock slots and upper strut mount. Strut shaft can be moved from one side of the strut tower's center hole to the other side.
  • Widest possible continuous range of caster adjustment, limited not by the plate, but by the strut shaft contacting the rear edge of the strut tower's center hole.
  • PTFE lined spherical bearing was designed by MM, and is custom manufactured in the U.S.A. Spherical bearing allows proper articulation, unlike urethane-bushed camber plates.
  • Main plate is a high-grade alloy steel that is much stronger than mild steel, and has a much longer fatigue life than aluminum.
  • Includes progressive-rate bumpstops (for use with struts other than MM and Bilstein).
  • Retains stock strut dustcovers in applications using struts other than MM and Bilstein.
  • Steel components are either zinc plated or powder coated for great looks and long lasting protection.
  • Chrome main plate is optional.
  • Designed and manufactured in the U.S.A. by Maximum Motorsports.
  • MMCC7989 fits 1979-89 Mustang chassis, all engines.
  • MMCC7989 does NOT properly fit any other Fox chassis (1990-93 Mustang, 1983-88 Thunderbird, 1984-92 Lincoln Mark VII) because of differences in the pattern of slots and holes in the strut towers.

Strange struts

  • For unknown reasons, Strange makes their strut shaft undersized. It is 0.619" in diameter instead of the standard Mustang size of 0.629" (16mm). This allows the strut shaft to move within the 16mm spherical bearing, causing noise, unless the strut shaft retaining nut is extremely tight.
  • The design of the Strange strut causes very audible noise when the suspension moves. Many people assume the noise is caused by camber plates because they did not notice the noise when they had the stock upper strut mount installed along with their Strange struts. That assumption is incorrect. MM Caster Camber Plates do not make noise when in good working condition; they only make noise if the spherical bearing has been damaged. However, the spherical bearing does transmit noise more easily than does the stock rubber-bushed upper strut mount. Strange struts make noise from the internal workings of the valve, and MM caster camber Plates will transmit that noise into the car. The noise is caused by the Strange struts, not the camber plates.
  • Going with coil-overs? The MMCO-2 front coil-over conversion kit fits Strange struts.
