Manthey Racing x Porsche Performance Coilover Suspension Kit — 991.2 GT3 RS | Nürburgring-Validated

The combined weight of Porsche's engineering excellence and Manthey Racing's decades of GT racing experience went into every component of this coilover suspension kit. Developed through countless laps on international racetracks — and above all, meticulously refined on the Nürburgring Nordschleife — this is a factory-approved suspension system that brings genuine GT racing technology to your road-going 991.2 GT3 RS.

Front Axle — A McPherson upside-down design featuring a high-strength aluminum housing tube engineered to perform its wheel guidance function reliably and durably even under racetrack conditions. The damping unit offers 3-way adjustability, and the aluminum support bearings allow easy camber adjustment on the front axle for precise geometry tuning. The independent compression stage adjustment — both low and high speed — is handled via tool-free adjustment wheels on the external reservoir. Rebound damping is adjusted via a dedicated wheel at the lower end of the damper housing. Vehicles equipped with a standard front axle lift system retain full lift functionality.

Rear Axle — A fully aluminum shock absorber with four-way damping adjustability covering compression and rebound in both low and high speed settings. All adjustments are made directly on the damper housing via tool-free adjustment wheels — rapid, accessible, and precise enough for trackside setup changes between sessions.

The baseline setup for every component was determined through exhaustive testing by Porsche and Manthey engineers on the world's most demanding circuits, then meticulously fine-tuned lap by lap on the Nordschleife until nothing was left to chance.

Key Features:

Front McPherson upside-down design with high-strength aluminum housing
Front 3-way damping adjustment with independent low and high speed compression control via external reservoir
Front camber adjustment via aluminum support bearings
Full front axle lift system compatibility retained
Rear 4-way damping adjustment — compression and rebound at low and high speed

Warranty

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.

Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty.

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.
