Mustang MOD1 Front Suspension Package. By combining Mike Maier Inc’s years of Mustang experience we have been able to deliver a system that will make your ride handle. With JRi’s unsurpassed damper system and Mike Maier Inc’s unique upper A-frame design we created the best possible front suspension system without making any major modifications to your chassis.

We combined our vast knowledge of geometry to ensure that your classic vehicle will handle through the corners in comfort.  By maximizing the motion ratio and shock stroke we can create a smooth ride that you have been looking for in your vehicle.

By using JRi’s superior damper system we are able to design a specific valving (Street, sport, race) and shock configuration for any type of vehicle.  Each damper system is designed around your vehicle to perform its best, be it on the street or at the track.

The design of our tubular upper control arm has our end user in mind.  We not only designed for geometry but also for ease of maintenance and adjustment. Using a screw in balljoint it can be replaced or shimmed in minutes.  We designed our tubular arms to include 4 degrees of caster to improve the handling of your vehicle.  Wondering why caster is so important to your vintage Mustang? Read this tech article here.

Our shaft kit is designed using delrin bushings due to its quiet operation and long lifetime.  Rod ends wear out quickly and produce squeaks and clunking noises where delrin does not.  Alignment keys can be replaced for additional caster adjustment in the upper control arm. Finally the shaft kit is completely removable and serviceable.

The MOD lower control arms have been designed out of necessity. Each attribute of this part is designed with a specific purpose. The quality design will ensure that you have the tools needed to get your Mustang dialed in and tuned up the wat you need it. The MOD lower control arms are the highest quality arm and strut rod assembly you can buy. Bolt onto your Mustang and have the tuning ability provided here. Buy it once and buy the best.

  • Quality screw-in ball joints
  • Inner rod end for camber/track adjustment

Valving Options

The MOD1 street coilover package has a stripped down non-adjustable JRi shock. The valving in the shock is tailored toward a touring ride – responsive with a tight compliance to handle the bumps with control. This system best fits the person who wants to get in and drive. This shock package is completely upgradeable to a multi adjustable shock system in the future.

The MOD1 sport coilover assembly has a single-adjustable JRi shock which is set up to adjust rebound. The single adjustable shock allows us to be more aggressive. The valving allows the car to handle like a slot car for unsurpassed control while having the ability to back off the dampening quickly to get back a refined drive for the trip home from the track. This shock package is upgradeable to a double adjustable shock in the future.

The MOD1 race coilover assembly features a double adjustable JRi shock. This is the shock package used on Mike and Brianne’s Ol Blue 1966 Mustang. The double adjustable JRi shock system allows the driver to independently tune low speed rebound vs. high speed rebound. This lets us tune the small inputs of the steering wheel to get the response desired while tuning the larger bumps out of the equation. The double adjustable JRi shock package is the most advanced shock system you can buy to refine your Mustang to the level you demand.

  1. Denton Mann

    Just finished the MOD1 install on my 70 Mach 1. I went with the single adjustable coilers as the car will see some track and autocross time as well as normal driving duties. I live in Australia so freight is always a big deal, MMI were able to package up once complete in a very efficient way to save on shipping and all the components arrived without damage.
    I had read through the instructions online quite a few times and having just rebuilt the front end less than 2 years ago, I kinda of knew what I was in for. The old components came out without any issues. The hardest part of the install was drilling out the spot welds on the upper coil spring pocket, but even that was only 10 minutes.

    When it came time to install the new parts, everything fit nice and tight without slop, what I would expect. the finish on both the MMI components and the JRI shocks were second to none. The threaded holes must have been tapped out after powder coating because there were no thread bind issues what so ever. My only concern with mounting the lower control arms into the mounting holes on the frame was the OD of the aluminium bushings. I was concerned that they may not have enough surface contact on the slotted holes to bite and not move around. The camber bolts have been staked, something Vince instructed most people do and believe there shouldn’t be an issue.

    Once the install was completed, I performed the alignment at home and found every move required was predictable and even got the thread count down to what degree change the move would make. This will come in handy if I feel I need to make changes in the future.

    Have had the car out once around the suburb to go through a bit of a shake down, the car feels tight, no squeaks and will put it through more punishment in an upcoming autocross session. Great product and was exactly what I was expecting.
