RSS – 986/996/987/997/981/982/718/997 GT2-GT3 (except 991 GT2-3 & RS,GT4) – XL Rear 2-Piece Complete LCA Kit- Pair of 2 (See LCA Fitment Notes)

#374 RSS Tarmac Series XL (Extra Long) 2-Piece Complete Lower Control Arm Kit – Rear Axle (Pair)

The RSS Tarmac Series XL (Extra Long) Rear Lower Control Arm Kit is engineered for Porsche® 986, 996, 997, 987, and 981/982/718 models, delivering maximum adjustability and precision for aggressive, performance-oriented setups. The extended-length design is ideal for vehicles running lowered ride heights, reduced suspension travel, and increased negative camber—providing the additional range needed to properly correct rear suspension geometry.

Built for motorsport applications, this system features adjustable, non-hydraulic thrust arm bushings combined with spherical monoball ends to eliminate compliance and maintain precise control under load. By removing the deflection associated with factory rubber components, the XL control arms provide more consistent handling, improved stability, and enhanced driver feedback.

Kit Includes:

• Adjustable, non-hydraulic replacement thrust arm bushings
• Spherical monoball ends for precise articulation
• Shim kit (1mm / 2mm / 3mm / 7mm) for fine geometry adjustment

Key Features:

• Extra-long design for increased rear geometry correction and adjustability
• Optimized for lowered vehicles with reduced suspension travel
• Eliminates rubber bushing deflection for consistent, predictable performance
• Improves rear-end stability, traction, and driver feedback
• Allows precise tuning of suspension geometry via included shims
• Motorsport-grade construction for strength, durability, and serviceability

Performance Benefits:
Factory suspension components are designed with comfort in mind, utilizing rubber bushings to reduce noise and vibration. However, under load, these bushings deflect—causing unwanted suspension movement and even temporary changes in effective spring rates. The RSS Tarmac Series XL Control Arms eliminate this compromise, creating a direct and consistent connection between the chassis and suspension. This results in reduced driver correction, increased confidence, and improved performance in high-demand driving conditions.
