Track Proven MCS Suspension for the Porsche 981 and 718 GT4

The Porsche 981 and 718 GT4 are some of the most balanced modern track cars available, with a mid engine layout, serious brakes and real aero right from the factory. As you start to push harder, especially with more aggressive alignment and tires, the stock dampers and settings can become the limiting factor. Motion Control Suspension solves that. Built in the USA and proven in championship winning race programs, MCS dampers deliver the control, consistency and feedback that the GT4 platform deserves.

With extensive experience on Porsche GT cars, we have seen consistent gains in pace, tire life and driver confidence compared to factory suspension setups. We have set multiple lap records in Porsche and BMW platforms using MCS systems, and this is the package we trust when a 981 or 718 GT4 needs to work on both street and track.

Why Choose MCS for Your 981 or 718 GT4

• Motorsport bred: Developed by a team with decades of professional racing and OEM development experience, proven in major GT and endurance programs.
• Real performance gains: Increased mechanical grip, better platform control and more confidence on turn in and corner exit translate directly into faster, more consistent laps.
• Street friendly, track ready: Thoughtful valving and high quality internals mean improved ride quality on the street with far more control on track than the stock dampers.
• More robust and fully rebuildable: MCS hardware is designed for long service life and is completely serviceable and revalveable as your program evolves.
• Made and serviced in the USA: Built, assembled and supported in the United States for quick turnaround and straightforward service.
• Fast, knowledgeable support: You are working with a race shop that runs, tunes and wins on MCS dampers, not just a reseller.

Built Around the GT4 Chassis

The 981 and 718 GT4 put significant load into the suspension under heavy braking, curb usage and high speed aero corners. The factory dampers are a compromise between comfort, cost and ultimate track performance. Once you add more tire and more aggressive alignment, they can feel underdamped and inconsistent over a full session. MCS monotube construction, large piston area and precise adjusters give the chassis the support it needs while keeping the car predictable and confidence inspiring at the limit.

With a properly set up MCS package, steering response sharpens, mid corner balance becomes easier to trust and traction off slow and medium speed corners improves. Whether you are focused on HPDE, time attack or club racing, this system gives you the tuning range to match tire, aero and driving style while preserving what makes the GT4 so rewarding to drive.

RWE Curated Assemblies

Most off the shelf coilover kits are built to a single compromise that does not really suit anyone perfectly. We approach it differently. Every MCS GT4 kit we sell is specified, assembled and checked in house with your goals in mind.

• Street / Track Package
  Ideal for GT4s that still see street duty but are driven hard at the track. Spring rates and baseline settings are chosen to keep the car composed on the road while remaining fully capable in HPDE and open lapping environments.
• Custom Package
  For more focused builds such as heavy aero cars, wider slicks or dedicated time attack and wheel to wheel programs, we can spec a fully custom package. Choose the “Custom” option in the Assembly menu and we will consult with you on damper configuration, spring rates and overall setup to match your goals and experience level.

Our complete assemblies typically include MCS dampers, our spec main and helper springs and MCS rear bearing plates. The bearing plates and hardware reduce stack height and improve adjustment range, giving you more flexibility with ride height and alignment. All components are assembled, torqued and paint marked in house so you receive a true ready to bolt on solution.

MCS Damper Configuration Options

The 981 and 718 GT4 kit is available in several MCS configurations so you can match adjustment range and complexity to how you use the car. All share the same build quality and core piston design, with the difference being how many adjustments you have and how wide the tuning window is.

• 1 Way Non-Remote
  A single adjustment that changes rebound and compression together. Simple to use, ideal for mixed street and track cars and drivers who want a noticeable improvement without having to chase separate settings at every event.
• 2 Way Non-Remote
  Independent rebound and compression adjustment on the damper body. This gives you more control over how the car responds on entry versus over bumps and curbs, without the packaging complexity of remote canisters.
• 2 Way Remote
  Adds remote canisters with separate compression adjustment. The extra oil volume and finer control improve heat management and consistency during long sessions while giving you a wider usable adjustment range.
• 3 Way Remote
  Separate rebound and independent high and low speed compression adjustments. This lets you tune support for braking and aero separately from compliance over bumps, ideal for serious track and time attack cars.
• 4 Way Remote
  Maximum adjustment range and resolution, with independent rebound and high and low speed compression control. Best suited for dedicated race and heavy aero cars where you want to fine tune the chassis for specific tracks, tires and conditions.

Street / Track and Custom spring and setup options are available across these MCS configurations. For a deeper dive into the differences between each option and recommendations for your use case, visit our MCS Assembly Option Information page.

PASM Warning Notes

On PASM equipped cars, replacing the factory dampers will trigger suspension fault warnings unless a PASM delete solution or coding is implemented. A PASM delete kit is not included with this package and must be sourced or performed separately by your shop or installer.

Custom Tuning Available

No two builds or drivers are exactly the same. If you have a specific use case, such as heavy aero, particular tire sizes, endurance racing programs or strict NVH requirements for a dual purpose car, we can tailor the package to match. Spring rates, nitrogen pressure and custom valving are available by request. Choose the “Custom” option at checkout and include your contact information. We will reach out to review your current setup, goals and experience level before finalizing the spec.

Custom valving and special order configurations may add lead time depending on season and demand.

In Stock and Ready to Ship

We keep popular 981 and 718 GT4 MCS systems and spring combinations in stock and can usually ship complete kits within one business day when all components are on the shelf. Order a complete kit and we will ship a fully assembled, ready to bolt on damper package, torqued to spec and paint marked so you can install with confidence.

If you are not sure which package is right for you, reach out for a quick consultation and we will help you choose the right system for your GT4 and your driving.
