What Are RSS Porsche Parts?
RSS, short for RennSport, is a German engineering company that has been producing high-quality performance parts for Porsche vehicles for decades. Their product line focuses on mechanical upgrades that enhance the driving experience without sacrificing daily usability. Unlike cosmetic modifications, RSS parts are functional—they make your Porsche faster, more precise, and more reliable under aggressive driving conditions.
Common RSS products include:
- Clutch kits (single-mass flywheel and clutch sets)
- Short shifters and shift rods
- Engine and transmission mounts
- Suspension bushings and control arms
- Oil pans and baffles
- Flywheels and lightweight components
These parts are engineered to OEM+ specifications, meaning they improve on factory design while maintaining proper fitment and durability.
Why Choose RSS for Your Porsche?
Many Porsche owners opt for RSS because of the brand’s reputation for quality and performance. RSS parts are often used in track and motorsport applications due to their reliability. For example, their clutch kits provide a more positive engagement and better heat dissipation compared to stock units, making them ideal for track days or spirited driving.
Another advantage is that RSS focuses on mechanical feel. Their short shifter kits reduce throw length by up to 30%, giving you a more direct and satisfying shift experience. Similarly, their engine mounts minimize drivetrain movement during hard acceleration, improving throttle response and stability.
RSS also supports a wide range of Porsche models, including air-cooled 911s (964, 993), water-cooled 996, 997, 991, 992, as well as the Cayman (987, 981, 718) and Boxster. This broad coverage means you can find parts for both vintage and modern cars.
Popular RSS Porsche Parts by Model
For Air-Cooled 911 (964, 993)
Air-cooled 911s benefit from RSS upgrades that address common weak points. The RSS single-mass flywheel and clutch kit reduces rotating mass, allowing the engine to rev more freely. This kit includes a pressure plate, disc, and flywheel—all balanced for smooth operation. Additionally, the RSS short shifter for the G50 transmission provides a crisp, mechanical feel that eliminates vagueness.
For Water-Cooled 996 and 997
For the 996 and 997, the RSS clutch kit is a popular upgrade, especially for turbo models. The stock dual-mass flywheel can fail under high power, so switching to a single-mass RSS unit improves reliability and response. The RSS engine mounts are also recommended to reduce engine movement during gear changes.
For 991 and 992
Newer 911s like the 991 and 992 have advanced electronics, but mechanical upgrades still enhance the driving experience. The RSS short shifter works with the manual transmission to tighten shift throws. For PDK cars, RSS offers shift paddles that provide a more tactile feel. Their suspension bushings also reduce compliance and improve steering precision.
For Cayman and Boxster (987, 981, 718)
Mid-engine Porsches like the Cayman and Boxster benefit from RSS drivetrain mounts that reduce flex under cornering. The RSS clutch kit is an excellent upgrade for track-focused owners, as it handles high RPM shifts without slipping. The short shifter kit is another favorite, as it eliminates the longer throws from the factory unit.
How to Select the Right RSS Parts
Choosing the correct RSS parts depends on your driving style and goals. Here are practical considerations:
- Street vs. Track: Most RSS clutch kits are streetable, but some are more aggressive. For daily driving, choose a kit with a sprung hub disc to reduce chatter. For track use, an unsprung disc provides quicker engagement.
- Transmission Type: RSS parts are specific to transmission models (G50, Getrag, etc.). Verify your transmission code before ordering.
- Engine Modifications: If you plan to increase power, select a clutch rated for higher torque. RSS offers stages (e.g., Stage 1 for stock power, Stage 2 for tuned cars).
- Model Year Interchange: While many parts are cross-compatible, some 991 parts differ from 997. Always double-check with the manufacturer or a reputable dealer.
Installation Considerations
Installing RSS parts requires mechanical skill. Clutch and flywheel swaps are labor-intensive and often require special tools. While some enthusiasts perform the work themselves, many opt for a professional shop with Porsche experience. Short shifters and mounts are easier DIY projects—you can often install them in a few hours.
Important tip: When installing a single-mass flywheel, ensure the ECU is reprogrammed or the engine may stall due to decreased rotational inertia. Some RSS kits include a reflash service, or you can use a standalone ECU.
Where to Buy Authentic RSS Parts
To avoid counterfeit products, purchase RSS parts from authorized distributors. Many specialty Porsche parts retailers stock RSS components. You can also contact RSS directly through their website for a list of recommended dealers. Be cautious of unknown sellers offering unusually low prices—counterfeit parts may fail catastrophically.
Final Recommendation
RSS Porsche parts are a solid investment for any enthusiast seeking improved performance and reliability. Focus on the specific part that addresses your biggest driving complaint—whether it’s sloppy shifting, clutch slip, or drivetrain slop. For most owners, starting with an RSS short shifter and engine mounts provides an immediate and noticeable upgrade. If you track your car, add a clutch kit and lightweight flywheel. Always verify compatibility and consider professional installation to ensure optimal results. With proper selection and installation, RSS parts will transform your Porsche’s character without compromising its everyday usability.
