Option 1

Customizing your K-member package means choosing the best combination of parts for your Mustang from the available options. Listed here are the options for each part in the package. You may be able to choose the most suitable part after reading through the descriptions in this section, but if you need help, knowing the available options makes your conversation with an MM Tech Associate go more smoothly. Just take it step by step, and all will become clear. Options appear in order of importance. Follow the links to the individual product pages and make note of your choices and questions.

Getting started
The heart of your Mustang's high-performance handling is the combination of springs and dampers. Spring rates should always be chosen first, before dampers, to suit your desired combination of performance and ride quality. In other words, the choice of spring rates guides the damper choice.

Springs
Front coil-over springs are available in a wide range of spring rates. While an MM Tech Associate can help you choose, please read the coil-over section of our Guide to Choosing Spring Rates and Dampers first. The goal is to choose a front spring rate that's at the intersection point of optimum handling and ride quality. Your preferred mix of handling and ride quality, and the choice of front spring rate to achieve that, is the single most important decision to make.

Dampers
If you already have front struts, confirm that your chosen front coil-over spring rate is within the range the struts can control. If you need struts, after picking spring rates the damper choice becomes easier. MM 3rd-Generation struts and shocks are available in 4 different series, with each matching a specific range of spring rates. This is detailed in our handy Guide to Choosing Spring Rates and Dampers.

Dampers available from MM:

• MM

• Bilstein

• Koni single-adjustable

• Koni double-adjustable

Coil-over Conversion Kit
The dampers you already have, or choose here, affect the model of the coil-over conversion kit required. MM Front Coil-over Kits fit specific struts; we don't make an ill-fitting universal kit like the others. The brand of strut on your car narrows down the choice of coil-over conversion kit to what fits your strut: Front coil-over kits.

Good work! Now go to the Options 2 tab.

Option 2:

K-member
Now for the core of the K-member package; choose one of these 3 MM K-members:

• MMKM-1 fits 1979-1995 Mustangs with an OEM engine type: 5.0L pushrod, 302, 351W, 4.2L, 3.8L, 2.3L.

• MMKM-2.1 fits 1979-1995 Mustangs with an engine swap: 4.6L/5.4L modular, 3.8L V6, 5.0L Coyote (2011-2014), or LSX engine.

• MMKM-3.1 fits 1979-1995 Mustangs swapped with a 4.6L modular engine and a Hellion turbo kit.

Note: An Oil Filter Relocation Kit is required for most applications with an OEM oil cooler. This includes all 4V Cobra 4.6L and some 2V GT 4.6L engines, but not the Coyote engines.

Front Control Arms
Choose one of the many different MM Front Control Arms available.

First decision
Choose Fox length or SN95 length:

• The MM Fox length arms slightly increase the track width, moving each front wheel outward 1/4" compared to stock control arms.

• The MM SN95 arms are longer than MM Fox arms and move each front wheel outboard an additional 0.9" over the MM Fox arms. Typically, competitive road racers use these to widen the front track for increased cornering grip. Note that extensive fender modifications are usually required with this option.

Second decision
Choose the offset. This refers to the fore-aft location of the ball joint relative to a stock front control arm:

• Reverse-Offset: When installed with an MM K-member, this option retains the stock wheel base. Used to keep the tire in the stock fore/aft location, causing no interference between the tire and the front of the fender.

• Non-Offset: When installed with an MM K-member, this option moves the front wheels forward by 3/4". Used to provide increased caster and slightly improved weight distribution. This option has potential for some tire interference (depends on tire size), but can usually be accommodated with minimal modifications that won't affect the exterior paint. We have instructions for the modifications.

• Forward-Offset: When installed with an MM K-member, this option moves the front wheels forward by 1.5". Used to provide significantly increased caster and move the center of gravity rearward, this set-up requires significant fender modifications for tire clearance.

• Drag Race: We omit the front swaybar endlink mount to reduce weight. This option is non-offset. See Non-Offset description above.

Third decision
Choose the pivot bushing material:

• Urethane offers excellent performance and slightly less NVH than Delrin bushings.

• Delrin is recommended for track-driven Mustangs due to much-increased longevity over urethane, along with reduced friction.

Making those 3 decisions will lead you to one of the control arms listed on these pages:

• Fox front control arms

• Fox drag race front control arms

• SN95 front control arms

Option 3:

Caster Camber Plates
Front coil-overs require steel caster camber plates with spherical bearings. Your Mustang's chassis year determines which MM Caster Camber Plates you'll need. Choose the main plate finish: either black powdercoating or chrome plating.

Bumpsteer Kit
Choose the bolt-through kit that matches your front control arms (Fox or SN95). If you're swapping an SN95 steering rack into your Fox chassis, read SN95 Steering Rack Upgrade for Fox Mustangs.

Front Swaybar Relocation Kit
The MM Fox Chassis Front Swaybar Relocation Kit (MMFSB-50) is required in all cases except when using the MM Reverse-Offset Front Control Arms. The swaybar relocation kit requires universal front swaybar bushings.

Front Swaybar Bushings
You need to make decisions about front swaybar pivot bushings:

• Which front control arms did you choose? The MM Reverse-Offset Control Arms do NOT require the Front Swaybar Relocation Kit, so use standard replacement swaybar pivot bushings.

• All other Front Control Arms require the MMFSB-50 Front Swaybar Relocation Kit, which in turn requires universal front swaybar bushings.

• After determining the type of bushings you'll need, select the correct bushing size for your swaybar diameter.

• Note that some aftermarket front swaybars include new standard replacement swaybar pivot bushings.

Steering Rack Bushings
No choices to make here; the MM K-member requires using MM's Aluminum Steering Rack Bushings (MMST-6). These let you install the steering rack higher or lower than stock.

Swaybar Endlinks
For standard front swaybars, the MM K-member requires endlinks that are shorter than stock.

Popular additions:

• MM Solid Steering Shaft

• MM Front Swaybar Bracket Reinforcements

• MM Strut Tower Brace

• Motor mounts

• Camber gauge

• Bumpsteer gauge
