For a dramatic improvement in front-end grip, nothing beats a Maximum Motorsports K-member package!
Less weight
A complete MM K-member package weighs considerably less than the stock items it replaces, reducing your Mustang's front-end weight by nearly 40 lb.
Better by design
We've optimized the suspension geometry on our K-members to make your Mustang's cornering grip and handling as close to perfect as possible. A major design goal was to maximize stiffness, since that keeps the suspension geometry stable when cornering. The extra stiffness makes the handling more precise and increases stability under braking. You end up with a ferocious but smooth-driving machine.
Like the OEM version, MM K-members are designed and built to last for the life of your Mustang. Our design priorities focus on bracing and triangulation of tube intersections to ensure the strength and durability required for this mission-critical part. We use thicker-gauge metal and larger tube sizes than other companies to make sure the MM K-member has the strength to handle drag race launches and wheel stands, road race use, and even the rigors of spirited daily street driving.
Features:
- Dramatically increased front-end grip when cornering.
- Improved cornering stability and predictability.
- Much quicker steering response.
- Reduced brake dive.
- Greater comfort when cornering due to reduced body roll.
- Amazing ride quality for a high-performance street setup-firm but not harsh, as expected of a true high-performance car.
- Ideal front ride height, because it's adjustable to suit your preference.
Fitmnet:
1979-1993 Mustangs equipped with certain specific items.
All 1979-1993 Mustangs must be equipped with the following parts to accommodate an MM K-member Package install:
- One of these engines: 5.0L pushrod, 302, 351W, 4.2L, 3.8L, 2.3L, 4.6L/5.4L modular, 3.8L V6, 5.0L Coyote (2011-2014), or LSX engine.
- An Oil Filter Relocation Kit is required for most Ford V8 engines that have an OEM oil cooler. This includes all 4V Cobra 4.6L and some 2V GT 4.6L engines, but not the Coyote engines.
- Struts suitable for use with a coil-over conversion. If you don't already have them, MM has a variety of high-quality suitable performance strut offerings.
- Your Mustang may require different spindles! Most high-performance struts require spindles from a 1987-1993 V8 Mustang or any 1994-2004 Mustang. Fitting performance struts to a 1979-1986 Mustang, and to a non-V8 1987-1993 Mustang, requires swapping to 1987-1993 V8 spindles or to SN95 spindles and brakes, and using struts from the 1987-1993 V8 group.
Steering Rack Notes
- Manual rack on MM KM-1 and MMKM-1.1 requires MMST-8 Steering Rack Spacers in addition to the MMST-6 Steering Rack Bushings.
- Flaming River power rack on MM KM-1 and MMKM-1.1 requires MMST-8 Steering Rack Spacers in addition to the MMST-6 Steering Rack Bushings.
1979-1982 Mustang K-member Mounts
- These model years have a unique distance between the two holes at each rear lower frame rail mount. You will need either stock nut plates from a 1983-2004 Mustang or four nuts and thick flat washers. Minimal grinding may be necessary on a 1979-1982 Mustang's rear mount to match its wider hole spacing to the narrower spacing of the slots on the MM K-member (matches 1983-2004 Mustangs).
1979-1984 Mustang Steering Rack Mounting
- Mustangs built from 1979 through 10/1/84 have 14mm bolts holding the steering rack to the K-member. You'll need a pair of 1985-2004 Mustang 12mm steering rack mounting bolts and nuts to attach the steering rack to the MM K-member. Caution: Some aftermarket companies sell SAE bolts for this application, but they do NOT fit. You must use the OEM-size 12mm metric hardware.
2015+ Coyote engine fitment
The 2015+ Mustang GT Coyote engines have Charge Motion Control Valves (CMCV), also known as intake manifold runner controls. The manifold runners have air valves that are moved by vacuum motors located at the back of the intake manifold. The movement is controlled by the ECU. The purpose is to provide better idle control and higher torque at low RPM's. The GT350 intake manifold also has CMCV and the vacuum motors.
The Problem
The CMCV vacuum motors on a 2015+ Coyote engine interfere with the Fox/SN95 firewall when the engine is mounted in the typical location, as dictated by standard 4.6L motor mounts.
Ford Performance no longer sells production 2011-2014 Coyote engines. The only production engines they sell now are 2015+ models.
Solutions
- Mount the engine 0.75" further forward than the location set by standard 4.6L motor mounts. See "Relocating the engine" below for how to do this.
- Remove the vacuum motors, which will require modifications to the intake manifold to disable the CMCV, along with a custom engine tune.
- Install a 2011-2014 GT intake manifold, which does not have CMCV, and which will require a custom engine tune.
- Install a Boss 302 manifold, which does not have CMCV, and which will also require a custom engine tune.
Relocating the engine
- Different motor mounts are required. Currently available motor mounts can be modified to move the engine 0.75" forward: 6-504-Bl or MMSMM-2.
- Coming soon! Use our new solid motor mounts that do not require modification to mount the engine forward.
- Coming soon! Use our new urethane mounts that do not require modification to mount the engine forward.
MM K-member changes for engine relocation We changed our MMKM-2.1 K-member to accommodate the Coyote oil pan when the engine is moved forward. The only change is to the design of the brace for the main tube. The new design provides clearance for the relocated oil pan.
- All MMKM-2.1 K-members shipped after August 1, 2018 are of the new design.
The original MM K-member design can be modified to eliminate the interference. Fabrication and welding are required.
