Track Proven MCS Suspension for the Porsche 991 GT3 RS and GT2 RS With Front Axle Lift

The Porsche 991 GT3 RS and GT2 RS are benchmark track cars, with serious aero, wide tires and huge braking capacity. As you start to lean on them harder, the stock Bilstein dampers and factory settings can limit how much confidence you have at the limit. 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 991 GT platform deserves.

With extensive testing on Porsche GT cars, we have seen consistent gains in pace, tire life and driver confidence compared to the factory suspension. We have set multiple lap records in Porsche and BMW platforms using MCS systems, and this is the package we trust when a 991 GT3 RS or GT2 RS needs to work on both street and track.

Why Choose MCS for Your 991 GT3 RS or GT2 RS

• Motorsport bred: Developed by a team with decades of professional racing and OEM development experience, proven in major endurance and GT 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 PASM 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.
• Track developed: MCS dampers are proven on modern GT and endurance racing platforms rather than adapted from generic street coilovers.
• 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 991 GT Platform

The 991 GT3 RS and GT2 RS put huge loads into the suspension under braking, over curbs and through high speed aero corners. The factory dampers are a compromise between comfort, cost and track performance. MCS monotube construction, large piston area and precise adjusters give the chassis the support it needs while keeping the car predictable at the limit.

With a properly set up MCS package, the car responds more cleanly to steering and brake inputs, holds a more stable platform through quick transitions and puts power down with improved traction on corner exit. Whether you primarily run HPDE, club racing or time attack, this system gives you the range to tune for tire, aero and driving style.

Front Axle Lift Compatible Design

Many coilover packages for the 991 GT cars require deleting the factory Front Axle Lift system. This kit is different. It is specifically designed for 991 GT3 RS and GT2 RS models equipped with the OEM pneumatic front axle lift, allowing you to keep full lift functionality while upgrading to true motorsport dampers.^*

As part of our assembly service, we can provide packaging and a shipping label so you can send your original front dampers to us. We remove the factory FAL sleeves, install them on your new MCS struts with fresh seals and then return a fully assembled kit ready to bolt on, at no additional labor charge. You keep the convenience of the factory lift system with the performance of MCS.

^*Designed for cars with factory Front Axle Lift. If you are unsure about compatibility, contact us with your VIN and current suspension configuration.

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 991 GT3 RS and GT2 RS kit we sell is specified, assembled and checked in house with your goals in mind.

• Street / Track Package
  Ideal for cars that still see some street mileage 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 front and rear bearing plates. The bearing plates reduce stack height and allow for additional ride height adjustment and alignment freedom. 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 991 GT3 RS and GT2 RS FAL 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

Because this kit replaces the factory PASM dampers, a PASM delete solution or coding is required to clear suspension warning lights. 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 991 GT3 RS and GT2 RS 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 991 GT car and your driving.
