Manthey Racing x Porsche Semi-Active Coilover Suspension Kit — 992 GT3 RS | The Pinnacle of Road-Going Suspension Technology

Eau Rouge. Parabolica. Fuchsröhre. These are the legendary corners that have shaped Manthey Racing's relentless pursuit of perfection — and it is on circuits like these that this semi-active coilover suspension was born. Subjected to countless endurance tests and refined lap after lap on the world's most demanding racetracks, this is the most sophisticated suspension system ever offered for a road-going Porsche. Nothing else comes close.

At its core, this system replaces the GT3 RS's standard single-valve dampers with an entirely new generation of dual-valve dampers — featuring separate valves for compression and rebound damping that operate independently of each other. Working in conjunction with a newly developed control unit and an array of four wheel acceleration sensors and three body acceleration sensors, the system continuously monitors and adjusts damping in real time, automatically adapting to every change in road surface, driving situation, and chassis load. The result is a level of suspension precision and response that simply cannot be achieved with conventional passive damper technology.

Spring rates have been specifically optimized for the GT3 RS's elevated downforce values — +30% on the front axle and +15% on the rear axle — delivering sharper turn-in, improved balance, and greater stability at the limit whether you're on a mountain road or chasing a lap record.

Three driving modes provide distinct baseline damper characteristics to suit any situation. In Track mode, the base setup can be further fine-tuned manually via the steering wheel — putting complete suspension control at your fingertips without ever leaving the cockpit.

Key Features:

  • Semi-active dual-valve dampers with independent compression and rebound control
  • Real-time automatic damper adjustment via 4 wheel + 3 body acceleration sensors
  • Newly developed control unit for maximum precision and response speed
  • Optimized spring rates: +30% front axle, +15% rear axle — tuned for GT3 RS downforce levels
  • Three driving modes: Normal, Sport, Track
  • Manual fine-tuning available in Track mode via steering wheel controls
  • Developed and perfected through extensive endurance testing on world-class racing circuits
  • Road approval and factory warranty remain fully unchanged

Compatibility: Fits Porsche 992 GT3 RS models. Dealer programming required for installation.

For best results and warranty coverage, installation and programming by a Manthey-certified dealer is strongly recommended. Special order — contact us for availability and lead times.

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

  • Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
  • Warranty claims must be processed in person at an authorized Porsche Service Center
  • Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
  • If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
  • Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

  • Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
  • Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
  • Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
  • Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

  • Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
  • A completed warranty certificate
  • Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.

Additional Warranty Terms & Legal Disclaimers

This warranty provides you with specific legal rights. You may also have additional rights that vary by state.

Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty. The exclusive remedy under this warranty is the repair or replacement of the defective part.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.

Some states do not permit limitations on implied warranty duration or the exclusion of incidental or consequential damages — the above limitations may not apply in your state.
