Have you ever Googled balljoint technology?

Does it annoy you when your significant other won’t listen to you explain caster trail? Are you not sure what caster trail is, but are game to learn more about it? The Mustang Apex Package might be the right setup for your car.

We call this the Apex Package for a reason: simply put, it’s composed of the most hardcore versions of everything we sell at MMI. It’s the combination of parts that we’ve beat on weekend after weekend at events like Optima, Goodguys, GridLife, and too many track days to count. We’ve spent more than a decade developing, designing, and refining this package.

The primary focus of Apex is adjustability. Nearly every part included replaces a stock part that wasn’t originally adjustable. Though this may seem overwhelming and perhaps a touch intimidating, it was done with one purpose: to give you the ability to grow into it without having to buy more stuff down the line. This is a package that will keep you happy from your first time on the track to your 1,000th time because of the flexibility it offers. Easily swap springs, shocks, shock valving, roll center, weight balance, you name it. It can adapt to your driving style, the type of event, the track, and more, all with basic hand tools.

Have a particular engine in mind? Maybe a Coyote? Or a NASCAR engine? It can adapt to that as well. Want to set it up for rallying? Yup, it can handle that. Apex was designed to be the final word in Mustang suspension and it has the win record to back it up.

How many classic Mustangs have you seen with the coilovers in the trunk?

 Yeah, it looks badass but honestly the looks were an afterthought. We put the coilovers in trunk for a reason: shock length.

You see shock length is ultimately what’s responsible for the ride quality and capability of the shock. Most rear systems are designed to do one thing well. Maybe they’re okay on a track, but they’ll break your back on the way home. Maybe they’re cushy on the street, but they toss you around on the track. And no amount of dialing up or dialing down the valving seems to help.

That’s why we designed our MOD 2 rear to incorporate a full sized shock. The only problem was we couldn’t fit it under the rear floor of the Mustang without giving it an SUV ride height. So we adopted technology more commonly seen on formula 1 cars than in Detroit, a cantilever system. By putting a pivot point between a pushrod tied to the rear end housing and the shock itself, we could lay the shocks down horizontally, giving us all the room we needed (and a bonus point of adjustment).

It looks cool, it works great, and you can lay it all out on the autocross then drive over railroad tracks with a cup of coffee in your hand on your way home.

You live and breathe Mustang.

Whether it’s tinkering with it, driving it to shows, or just arm chair racing against your buddies, your Mustang holds a special place in your heart. It’s practically a member of the family, so it deserves something a little special.

The plan isn’t to beat on it every weekend, but it should rise to the occasion when called. Want to hit up an autocross? It’s ready to go. Track Night in America? You bet. One Lap of America? Sure, why not. You need something that will hold it’s own but won’t break the bank or completely reengineer your car.

Welcome to the Blacktop Package.

This package is geared toward the guy who appreciates working on classic cars and wants something a little more involved than what you’d find in the Spec+ Package. It’s a complete package that replaces and evolves the entire front and rear suspension, brakes, steering, and chassis. Some minor welding will be required (for the subframe connectors) but the rest of the package is bolt on, requiring the use of typical hand tools. Blacktop is the last stop before we start talking more involved installations.

And this thing rips like you wouldn’t believe.

You’re here because you just inherited a Mustang.

Or maybe you’re about to pick up a classic to work on with your kids. Maybe you’ve had a car sitting in the garage under a cover and you’d like to get it out again. Whatever the situation is, you have trouble trusting the car. It’s twitchy, it wanders around the highway, the drive is harsh, the steering a little vague – everything about the car just feels… off.

These are the types of complaints we’ve heard from countless Mustang owners, even those who have spent thousands on all new parts only to have the car feel worse than it did when they started. This is how those cars end up in the garage, covered and forgotten.

That’s why we built on Spec+ Package. It’s a group of parts, a recipe if you will, to help build confidence, control and trust in these old cars. Repeatedly tested and loved, our goal is to get you back on the road with a complete system that works together to deliver a feeling.

Now make no mistake, this is not our “base” package. It’s not a mixture of crappy parts we threw together to make something “affordable” and try to get you to upgrade. No, this kit is composed of some of the best parts we’ve been able to source for a vintage Mustang with a few of our own touches to enhance drivability, stability, and handling. It’s not a race car kit. We would not recommend this setup if your goal is to dominate the local track scene. But if your goal is to dominate the local winery scene, or feel comfortable cruising to and from the mountains, this is the one you’re after (though we have seen this kit pull 1.1Gs in the turns).
