Kits

The Silver Rocket DRS-2 Motorsport Wing and 4.3x3.0 Riser Kit is a combined rear aerodynamic package developed for Porsche 992.1 and 992.2 GT3 models. It pairs a dry carbon fibre wing with CC-1 composite risers that move the aerofoil 4.3 inches higher and 3.0 inches rearward.

Fits:
Porsche 992.1 GT3 4.0L / 2021-24
Porsche 992.2 GT3 2025>>

What This Product Does

The package changes the position and profile of the rear wing to provide a wider range of aerodynamic adjustment. The raised, rearward location is intended to let the aerofoil produce equivalent loading at a lower angle of attack, while also improving the view through the rear window. Its six-position adjustment system enables the rear aerodynamic setting to be configured around the vehicle and its intended use.

Functions

• Manages airflow across the rear of the vehicle
• Provides six selectable angle-of-attack positions
• Raises the wing by 4.3 inches and moves it rearward by 3.0 inches
• Allows rear aerodynamic loading to be adjusted
• Improves rearward visibility compared with the standard wing position
• Creates a Cup car-influenced rear profile

Technical Details

• Wing manufactured from aerospace-grade dry carbon fibre
• CFD-developed wing section with an integrated Gurney flap
• Full carbon frame structure replaces conventional aluminium internal framing
• Six wing settings compared with four positions on the factory 992 GT3 system
• CC-1 carbon composite risers with an OEM-style aluminium-textured surface
• Risers are manufacturer-rated to withstand up to 600 kg of aerodynamic load

SilverRocket states that its CC-1 composite is four times stronger and 48% lighter than aluminium. The risers use the original mounting arrangement without requiring additional drilling, while the wing features high-gloss exposed carbon designed to coordinate with factory Weissach Package carbon components. The DRS-2 endplate profile takes styling cues from the Porsche 935 “Moby Dick”.

At its maximum setting, Silver Rocket reports that the DRS-2 wing produces 75% more downforce than the original 992 GT3 wing, with a 14.3% increase in drag. Positions one to four can be aligned with the corresponding factory wing settings as an initial setup reference, while positions five and six extend the available adjustment range.

Symptoms of Fault

• Cracking near the aerofoil or riser mounting points
• Wing movement or vibration while driving
• Rattling from loose or worn fasteners
• Carbon fibre delamination or clear-coat deterioration
• Uneven positioning across the rear bodywork
• Contact between the wing assembly and adjacent panels

Why Replacement Matters

Loose, damaged or incorrectly positioned aero components can cause vibration, noise and inconsistent airflow. All mounting points, fasteners and panel clearances should be inspected during installation. Correct alignment and angle selection are particularly important for vehicles used on track, so specialist fitting and aerodynamic setup are recommended.

FAQs

• Is this a universal rear wing?
  No. Both components are designed specifically around the Porsche 992.1 and 992.2 GT3 mounting arrangement.
• How many adjustment positions does the wing provide?
  The DRS-2 has six angle-of-attack settings, extending the adjustment range beyond the four-position factory system.
• Does fitting require additional drilling?
  The CC-1 risers are designed to use the factory mounting locations without extra holes or complex body modifications.
• Should the kit be professionally installed?
  Specialist installation is advisable to verify fastener security, wing alignment, panel clearance and the appropriate aerodynamic setting.

Valve Stem Seal Kit, Set Of 8.
The Victor Reinz Valve Stem Seal Kit is a set of 8 replacement valve stem seals designed to control the amount of engine oil reaching the valve stems and valve guides within the cylinder head.

Fits:

• Porsche 944 Turbo 2.5L 8V 1985-88
• Porsche 944 Turbo 2.5L 8V 1989-91
• Porsche 944 Turbo S 2.5L 8V 1988  

Diagram Ref No 12

Valve stem seals are small but important engine components. They allow the valve stems to receive the lubrication they require while preventing excessive engine oil from entering the combustion chambers.

As valve stem seals age, they can harden, crack or lose their ability to seal effectively. Excessive oil can then pass down the valve guides and enter the combustion chamber, potentially causing blue exhaust smoke, increased oil consumption, spark plug fouling and carbon deposits.

What This Product Does:
Each engine valve moves repeatedly through a valve guide as the engine operates. These moving surfaces require lubrication, but too much oil entering the valve guide area can allow engine oil to reach the combustion chamber.

The valve stem seal provides controlled sealing around the valve stem.

It allows sufficient lubrication for the valve and guide while restricting excessive oil from travelling down the valve stem.

Correctly functioning valve stem seals help:

• Control oil around the valve stems and guides
• Prevent excessive oil entering the combustion chambers
• Reduce unnecessary engine oil consumption
• Minimise oil-related exhaust smoke
• Reduce carbon deposits
• Help prevent spark plug contamination
• Support clean and efficient combustion

Symptoms Of Wear Or Failure:
Valve stem seals are continuously exposed to engine oil, high cylinder-head temperatures and rapid valve movement. Over time, the sealing material can become hard, brittle or worn.

Common symptoms of deteriorated valve stem seals include:

• Blue or blue-grey exhaust smoke
• Smoke immediately after engine start-up
• Exhaust smoke after the vehicle has been idling
• Smoke after prolonged engine braking or deceleration
• Increased engine oil consumption
• Oil-fouled spark plugs
• Carbon deposits in the combustion chambers
• Increased exhaust emissions
• Oil deposits within the exhaust system
• Gradual deterioration in engine performance

One particularly common indication is a brief cloud of blue smoke when starting the engine after it has been parked. Oil can seep past worn seals while the engine is stationary and then burn when the engine is started.

Why Replacement Matters:
Worn valve stem seals can result in much more than visible exhaust smoke.

Continued oil entering the combustion chamber can contribute to:

• Excessive engine oil consumption
• Spark plug fouling
• Carbon accumulation
• Increased exhaust emissions
• Contamination of exhaust components
• Reduced combustion efficiency
• Potential catalytic converter contamination over time

Replacing worn seals restores more effective control over the amount of oil reaching the valve stems and combustion chambers.

This can help reduce oil consumption and smoke where deteriorated valve stem seals are confirmed as the cause.

Designed for compatible Porsche applications with PASM, this kit provides replacement components for the front spring assembly, making it ideal for repairing worn, corroded or damaged suspension components as part of a comprehensive front suspension overhaul.

The front coil springs support the weight of the vehicle while allowing the wheels to move over bumps and uneven road surfaces. Working together with the PASM-controlled dampers and associated suspension components, the springs help maintain the correct ride height, suspension geometry, steering response and overall chassis balance.

PASM electronically adjusts damper characteristics according to driving conditions and the selected driving mode. However, the system still depends on mechanically sound springs and mounting components. A weakened, sagging or broken spring can compromise suspension geometry and prevent the chassis from performing as intended.

Replacing deteriorated components with this OE Match Front Coil Spring Kit with PASM helps restore controlled suspension movement, correct vehicle stance and predictable handling.
