Track Proven MCS Suspension for the Toyota GR Supra A90

The Toyota GR Supra A90 is an incredibly capable platform out of the box, with a stiff chassis, wide track and a strong B58 powertrain. What it leaves on the table is mechanical grip, composure over bumps and confidence at the limit. That is where Motion Control Suspension comes in. Built in the USA and proven in championship winning race programs, MCS dampers deliver the control, consistency and feedback the A90 chassis really deserves.

With years of testing on our own and customer cars, we have seen consistent improvements in pace, tire wear and driver confidence compared to the OEM suspension. We have set multiple lap records in BMW and Porsche platforms using MCS systems and in our experience this is the solution we trust when an A90 needs to work on both street and track.

Why Choose MCS for Your A90 Supra

• Motorsport bred: Developed by a team with decades of professional racing and OEM development experience, including major endurance wins.
• 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 compared to the stock suspension.
• Fully serviceable and upgradeable: Every MCS damper is rebuildable and can be refreshed, revalved or upgraded as your program evolves.
• Track developed: MCS dampers are born from real motorsport programs, with hardware and valving proven on modern GT and endurance racing platforms.
• 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 A90 Chassis

The A90 GR Supra rides on a short wheelbase, front engine rear wheel drive layout that rewards a well controlled damper with good low speed support and compliance over bumps. MCS monotube construction, large shaft diameters and precise adjusters give you that support without making the car nervous or harsh. Turn in becomes cleaner, mid corner balance is easier to trust and traction off slower corners is significantly improved.

Whether you are driving in canyons, doing HPDE weekends or running time attack, this system gives you the range you need to dial the car in for tire choice, aero and driving style.

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 Supra kit we sell is specified, assembled and checked in house with your goals in mind.

• Street / Track Package
  Our go to option for a Supra that needs to do everything. Spring rates and settings are chosen to prioritize comfort and control on the street while remaining fully capable on track. This is the setup many customers daily drive and use for HPDE and track days.
• Custom Package
  For more focused builds, such as heavy aero cars, wider tires or dedicated track and time attack cars, 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 the required rear hardware for the A90 Supra. 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 A90 Supra 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.

Custom Tuning Available

No two builds or drivers are exactly the same. If you have a specific use case, such as heavy aero, a particular tire size, a dedicated time attack car or a street car that must stay within certain NVH limits, 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.

Coilover Rear vs Divorced Rear

The A90 Supra uses a divorced rear spring and damper layout from the factory. MCS allows you to keep a divorced rear configuration or convert to a full coilover rear depending on your goals, class rules and packaging preferences. We typically recommend the coilover rear for maximum adjustment range, corner weight accuracy and simplicity, but we can supply either layout. Choose your preferred configuration from the dropdown when ordering.

In Stock and Ready to Ship

We keep common A90 Supra 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 Supra and your driving.
