Description
Built to Handle Whatever You Throw At It
Meet our MOD 1 Front Suspension Package, the complete, do anything kit designed and built by the team at MMI.
By combining MMI’s years of Mustang experience we have been able to design and manufacture a system will perform on the street and track without the harshness of a typical coilover setup. Using our unique upper A-frame design and a custom-tuned JRi shock, we created the best possible front suspension system that doesn’t require any welding or extensive modification to car.
The kit combines our popular MOD 1 Coilover Kit, MOD Lower Control Arms and Adjustable Strut Rod, and the MOD Front Sway Bar. This will completely replace the front suspension on your early model Mustang. Not only will this improve your on track times, but it will transform how your car handles on the street and at highway speeds, delivering a confident and consistent feel.
This kit includes
- MOD 1 Coilover Kit
- Our Tubular Upper A-Frame Arms with MOD Shaft Kit
- JRi-MOD coilover shocks with characteristics tuned by MMI
- Hyperco springs
- Billet aluminum shock top mounts
- MOD Lower Control Arms and Strut Rod Assembly
- MOD Front Sway Bar with Grease-able Urethane Bushings and End Links
- Hardware kit
In our years of racing and testing our products on the track, we’ve learned quite a few things about building a suspension that handles well, but doesn’t break your back (or wallet). In essence, our understanding boils down to four key elements:
Geometry
Suspension geometry can make or break a suspension design. We’d encourage you to watch our video in the gallery above, but to put it simply, our design allows for a 50% improvement in shock/spring to wheel motion ratio. This results in a more responsive and agile shock, while allowing us to run a softer spring. This combination offers race-like agility, with comfortable, daily-driver street manners.
Shock Quality
JRi shocks are simply put, the best in the game. The modern mono-tube design ensure responsiveness and comfort. This is one area where we encourage people to spend as much as they’re comfortable with – the return on investment is huge. This kit comes with your choice of three custom setups (noted below).
Pivot Points
A suspension is only as good as the freedom of movement that it has. If your suspension is binding, it’s not performing. That why we engineered our own MOD Shaft kit with custom Delrin bushing instead of the more typical bearings. Why? Because the upper control arm only moves a fraction of a complete 360 degrees, we’ve seen upper arms actually dig divots into the bearings. So we went with a broader, central bearing surrounded by bushing to minimize wear and maximize serviceability. Servicing it requires no press or special tools (see video).
Ball Joints
A good ball joint is absolutely essential. That’s why we replaced the old press-in style with a modern screw in ball joint. This gives you a ton of flexibility in deciding the type of ball joint you’d like to run, and it makes replacing it as easy as a trip to the parts store.
Our upper arms also include a built in 4 degrees of caster and replacement alignment keys, allowing you to dial in the alignment of your classic Mustang.
Shock 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.

I spoke to Mike over the phone and decided to go with the MOD1 front end as I had a couple different types of events I wanted to compete in. The install was easy and once I had set the alignment up I got repeatability in my changes which was great. I was able to dial the caster up for the runway events and then put it back to the autocross and track settings with little issue. This set up has been on my car for 3 years now and has performed as I expected with ride quality better than I thought it would be. Great product.
