THIS ITEM IS BUILT TO ORDER AND WILL TAKE 2-4 WEEKS BEFORE SHIPPING.

The Levinson Performance Coilover System was developed for Porsche enthusiasts who expect exceptional handling, precise chassis control, and outstanding ride quality without compromise.

Rather than offering an off-the-shelf suspension, Levinson Performance partnered with one of Taiwan’s most respected suspension engineering and manufacturing companies, an OEM supplier with decades of experience producing premium suspension components for performance automotive brands worldwide. Every application is engineered specifically for its chassis with carefully selected spring rates, damper valving, and ride height ranges that complement the vehicle instead of forcing a one-size-fits-all solution.

Whether your Porsche is a daily driver, weekend canyon carver, autocross competitor, HPDE machine, or dedicated race car, the LPM Coilover System delivers sharper response, greater confidence, and exceptional composure while allowing the suspension to be tailored to your driving style through adjustable damping and optional spring rates.

Advanced Digressive Damping Technology

At the heart of every LPM Coilover is advanced digressive damper valving, a design favored in high-performance street and motorsport applications because it delivers exceptional body control without the harsh ride commonly associated with aggressive coilover systems.

Unlike conventional dampers that continuously increase resistance as suspension speed rises, digressive valving generates high damping force during low-speed suspension movement, then transitions to a flatter damping curve during high-speed impacts.

The result is a suspension that behaves differently depending on what the car is doing.

Exceptional Chassis Control

During cornering, braking, acceleration, and steering inputs, suspension movement occurs at relatively low shaft speeds.

In these conditions, the digressive valving produces firm damping forces that keep the chassis composed and predictable.

Benefits include:

• Sharper steering response
• Faster turn-in
• Reduced body roll
• Improved braking stability
• Better weight transfer control
• Increased driver confidence

Outstanding Ride Quality

When the suspension encounters potholes, expansion joints, rough pavement, or track curbing, shaft speeds increase dramatically.

Instead of becoming increasingly harsh, the digressive valve design reaches a controlled blow-off point where additional damping force increases very little. This allows the suspension to absorb sharp impacts while maintaining excellent wheel control, significantly reducing the harshness often associated with traditional performance coilovers.

The result is a suspension that feels remarkably composed during aggressive driving while remaining comfortable enough for everyday use.

Tuned for Your Driving Style

Every LPM Coilover features 30-position damping adjustment, allowing you to fine-tune suspension behavior for virtually any driving environment.

Choose softer settings for comfortable daily driving or increase damping for spirited mountain roads, autocross competition, track days, or dedicated race use.

To further tailor the suspension to your specific needs, optional spring rates are available for customers seeking a setup optimized for street driving, dual-purpose performance, or full competition use.

One suspension platform, multiple personalities.

NOTE: the rear torsion bars are to be removed during installation. The LPM system converts the 944 to a full spring system, rear dampers include springs fitted to the body.

Why Levinson Performance?

A suspension system is only as good as the engineering behind it.

The LPM Coilover System was selected because it meets the standards we demand for performance, durability, consistency, and real-world drivability. By combining proven premium manufacturing with Levinson Performance’s application-specific specifications, testing, and customer support, we’ve created a suspension package engineered specifically for Porsche enthusiasts who refuse to compromise between handling and comfort.

Choosing Your Spring Rates & Rear Torsion Bar Setup

One of the great things about the LPM coilover system is that it can be tailored to your driving style. Whether your 944 is a comfortable weekend cruiser, an autocross car, or a dedicated track machine, there’s a spring combination that will work well.

Our dampers use a digressive valving profile with a broad operating range, so both of our standard spring packages work exceptionally well without requiring custom shock valving. The decision really comes down to how you use the car and how you prefer it to feel.

CHOOSING FRONT AND REAR SPRING RATES

For most street-driven 944/968, we generally recommend keeping the front and rear spring rates fairly close together, typically with the rear 30%-50% stiffer than the front.

As the intended use becomes more track-focused, both front and rear spring rates can be increased together to provide greater body control, reduced body roll, and quicker transient response.

There is no single "correct" spring combination. Tire choice, ride height, sway bars, alignment, vehicle weight, and whether the factory rear torsion bars are retained all influence the ideal setup.

If you're unsure which combination is right for your car, we're always happy to help.

Rear Torsion Bars: Keep Them or Remove Them?

One of the most common questions we receive is whether the factory rear torsion bars should remain in the car after installing our rear coilovers.

The answer is simple: Both approaches work well.

Neither is universally “better.” They simply offer different advantages depending on what you’re trying to accomplish.

Keeping the Factory Torsion Bars

Many owners choose to leave the factory torsion bars in place, especially on cars that spend most of their lives on the street.

In this configuration, the torsion bars continue supporting part of the vehicle’s weight while the rear coil springs share the load. The two spring systems work together, giving you the benefits of modern adjustable coilovers while retaining the original torsion bar suspension.

For many owners, this is an excellent compromise.

Installation is simpler because the torsion bars do not have to be removed, and the car still feels unmistakably like a Porsche 944, just tighter, more composed, and significantly more adjustable than it was from the factory.

For a street-driven car, there is absolutely nothing wrong with this approach.

Removing the Torsion Bars

Owners looking for maximum tuning flexibility often choose to remove the torsion bars completely and allow the rear coil springs to carry the entire load.

While this can provide a modest weight savings, the biggest advantage isn’t outright performance... it’s convenience.

Changing torsion bars is one of the more labor-intensive jobs on a 944. If you later decide you’d like slightly softer springs for the street, firmer springs for track days, or simply want to experiment with chassis balance, changing torsion bars means another major suspension project.

With a true rear coilover setup, changing spring rates is quick, inexpensive, and requires only basic tools. Remove the bottom damper bolt, thread off the sprin retainer, swap springs, re-assemble. It's that easy.

Ride height adjustment becomes equally straightforward. Instead of re-indexing torsion bars and hoping you land exactly where you want, you simply turn the threaded spring perch until the desired ride height is reached.

Corner balancing also becomes much easier because each corner can be adjusted independently. This makes fine-tuning the chassis for competition use much faster and more precise.

For owners who enjoy continually refining their suspension setup, removing the torsion bars makes future adjustments dramatically easier.

Why Do Some Cars Use Both?

Seeing a 944 with both torsion bars and rear coil springs is completely normal.

The two spring systems are not working against each other. They’re simply sharing the job of supporting the car.

An easy way to picture it is two people carrying the same heavy box. Neither person is fighting the other. They’re simply each carrying part of the weight.

The same thing happens here.

The torsion bars carry part of the load, while the rear coil springs carry the rest. Changing the rear spring rate changes how much each contributes, but both continue working together.

This is one reason many dual-purpose street and track cars successfully retain the factory torsion bars.

Which Should I Choose?

For most owners, our recommendations are simple.

Keep the torsion bars if:

• The car is primarily street driven.
• You want the simplest installation.
• You don’t anticipate changing spring rates in the future.
• You prefer preserving the factory suspension architecture.

Remove the torsion bars if:

• You expect to tune the suspension over time.
• You plan to corner balance the car regularly.
• You anticipate changing spring rates as your driving evolves.
• You want the simplest ride height adjustments and the greatest long-term flexibility.

Neither choice is wrong.

The beauty of the 944 platform is that it works exceptionally well either way. Whether you retain the factory torsion bars or convert to a full rear coilover arrangement, the LPM system delivers dramatically improved body control, steering response, and driver confidence while giving you a suspension that can evolve along with your car.
