Please get familiar with the parts included in the K-member package, as listed on the Options tab. Many parts are available in multiple varieties. While it's pretty common to need help from an MM Tech Associate to decide which variety of any particular part is best for your Mustang, when you understand the basic options we can help you better.

Once you have a list of the exact parts you need, either place your order from this page and then type your list of parts into the Comments field located on the checkout page, or place your order by phone.

Keep in mind that customization also means that we can delete items from a K-member package. If you already have some parts from another manufacturer, let us know and we'll check to see if they all play nicely together. On the other hand, if you're ready to load up your Mustang with a complete engineer-designed and track-tested K-member package, we'll hook you up.

The basic kit on this page does not include front struts because most people have already upgraded their Mustang's dampers before they consider more extensive modifications such as a K-member. While the basic K-member package starting price shown does not include struts, adding struts to the package is easy; just tell us what you'd like, or ask us to help you choose what's best for your Mustang. After you place an order, we'll give you a sales quote detailing all the parts you've chosen for your customized K-member package, showing the current pricing.

What's my next step, you ask? Go to the Options tab. Or the Help Me tab.

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.

• 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.

• MMKM-2 fits 1996-2004 Mustangs with engine type: 4.6L/5.4L modular, 3.8L V6, 5.0L Coyote (2011-2014), or LSX engine
• MMKM-1.1 fits 1996-2004 Mustangs with an engine swap: 5.0L pushrod, 302, 351W, 4.2L, 3.8L, 2.3L
• MMKM-3 fits 1996-2004 Mustangs 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.

• 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.
• 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 option has a small potential for some tire interference (depends on tire size and wheel offset), but can be accommodated with minimal modifications that do not affect the exterior paint.
• Drag Race: We omit the front swaybar endlink mount to reduce weight. This option is non-offset. See Non-Offset description above.

• 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.

• SN95 front control arms
• SN95 drag race front control arms

You're almost done! Now go to the Options 3 Tab.

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
No choice to make here; the MM K-members require a bolt-through style bumpsteer kit.

Front Swaybar Relocation Kit
The MM SN95 Chassis Front Swaybar Relocation Kit (MMFSB-51) is required in all cases. The swaybar relocation kit requires universal front swaybar bushings.

Front Swaybar Bushings
MM Front Control Arms require the MMFSB-51 Front Swaybar Relocation Kit, which in turn requires universal front swaybar bushings. Select the correct bushing size for your swaybar diameter.

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.

• MM Solid Steering Shaft
• MM Strut Tower Brace
• Motor mounts
• Camber gauge
• Bumpsteer gauge

That's it! That's the last decision to make. Now place your order, either by clicking the Add to Cart button and then writing your list of part numbers in the Comments field on the checkout page, or by calling us. When phoning, please have your written list of parts (and any questions) in hand.

Feeling a little overwhelmed by the choices required to set up a K-member package? If you really want the best for your Mustang and the fun of driving a truly awesome car, hang in there. It's really not so difficult. Even if you don't have extensive knowledge of automotive engineering and handling dynamics, have no fear! We're here for you.

First, familiarize yourself with the choices listed on the Options tab. You can probably make many of the required decisions on your own before you contact us just by knowing some basic information about your car. Next, select Maximum Grip Box Setup from the options listed on the Technical Services page and fill out the Maximum Grip Box Setup Form. We do charge for this service, of course, but it's refundable when you buy a K-member package directly from MM.

Once you send us your completed Maximum Grip Box Setup Form we'll lead you through the step-by-step process laid out in that form, answer your questions, and help you decide which parts are best for your Mustang.

If you autocross, open track, race, or would like to retain some aftermarket parts you already have, you'll require a higher level of technical help than most people. Thus, your Maximum Grip Box Setup Form will go to our setup engineer.

We look forward to talking with you. Here's to transforming your Mustang from sloppy to spectacular!

1. Read the Description tab.
2. Read the How to Order tab.
3. Make the choices on the Options tabs to the best of your ability.
4. If you get stuck, deploy the Maximum Grip Box Setup option on the Technical Services page.

What does the K-member package do?
It dramatically transforms your Mustang's front suspension design to a level far beyond what basic bolt-on parts can do. When you want your Mustang to handle well (unlike the average Mustang), you need both lighter weight and a high-performance front suspension design. MM's Engineering Team designed our K-member and related parts to improve the tires' grip on the pavement, which means faster and more stable cornering, which means more fun!

• Includes all the parts you need to install an MM K-member in one money-saving package!
• MM K-member improves your Mustang's handling by altering the suspension geometry. The two sets of pivot holes for mounting the front control arms let you install the FCAs at the best position to optimize the roll center height and improve the camber gain for the ride height you choose.
• Front control arm mounts are shifted 0.75" straight forward. This increases positive caster and moves the center of gravity slightly rearward for improved weight distribution when either Non-offset or Forward-offset front control arms are installed. Moving the center of gravity rearward improves braking, cornering, and acceleration grip as well as ride quality.
• Forward shift of the control arm location increases the Ackerman steering effect, which improves initial corner turn-in and reduces understeer.
• Lighter than stock: installing a complete MM K-member system reduces vehicle weight by nearly 40 lbs.
• Tough enough for street, strip, and road course use.
• MM Front Control Arms use OEM low-friction ball joints for the best performance and ride quality.
• MM Front Control Arms have a true "A" arm design, which is stronger and stiffer than the typical "V" arm.
• MM's bolt-through Bumpsteer Kit is stronger and stiffer than others and offers a greater range of adjustability.
• We make unique MM Coil-over Conversion Kits for specific brands of struts to ensure best fitment. These are not universal kits.
• The MM Front Swaybar Relocation Kit, required with Non-offset and Forward-offset front control arms, moves the swaybar forward to match the shifted position of the front control arms.
• Short swaybar endlinks keep the swaybar correctly aligned with the control arms, which are relocated by the raised pivot points of the MM K-member.

How do I choose which springs to use?
In general:
Choose springs that provide the handling characteristics and ride quality you want from your Mustang. Here's how to determine that:

• The front spring rate MUST be chosen in conjunction with the rear spring rate, rear spring location, and rear suspension configuration.
• Decide on your performance goal.
• Consider how you'll use your Mustang most of the time, and optimize it for that type of driving.
• Consider what level of ride quality you want. Then decide what (if any) compromises you'll make to achieve your performance goal.

In general, start by selecting a front spring rate that's appropriate for your Mustang's intended use. Then pick the rear spring rate to match, taking into account the rear suspension type (4-link, torque-arm, etc.).

More specifically:
See the MM Guide to Choosing Spring Rates and Dampers.

• Choose your spring rates first. That choice dictates the damper series selection.
• See the MM Guide to Choosing Spring Rates and Dampers.

Fore and Aft Wheel Location

The fore-aft location of your Mustang's front tires may change after installation of MM Front Control Arms, and will definitely change after installation of an MM K-member. How much it changes in either scenario depends on the specific combination of parts you install. The images below show the results of several combinations installed on a 1994-2004 Mustang.

Left image: No change in tire location, using either:

• Stock K-member and stock front control arms
• Stock K-member and MM Non-Offset Front Control Arms

Middle image: Tire moved forward 0.75", using either:

• MM K-member and MM Non-Offset Front Control Arms. The MM K-member adds 0.75" of forward offset.
• Stock K-member and MM Forward-Offset Front Control Arms. The MM Forward-Offset Front Control Arms add 0.75" of forward offset.

Right image: Tire moved forward 1.5", using:

• MM K-member and MM Forward-Offset Front Control Arms. The MM K-member adds 0.75" of forward offset and the MM Forward-Offset Front Control Arms add another 0.75" of forward offset, totaling 1.5" forward offset.
