Mustang MOD1 Coilover Kit. 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.

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.

    This product completely changes the handling characteristics of my 1965 Fastback. I’m not a racer, or auto-cross guy, however, I now feel totally in control of my car. Freeway on ramps with pot holes are no problem, neither are ruts, or un-level driving surfaces. Ride quality has dramatically improved through the bumps, and the ability to corner is amazing. I have so much more confidence in the control of the car, that auto-cross maybe in my future. The car now drives as good as it looks! Well worth the investment!
