RSS – 987/997/981/982/718/991 (except GT2-3 & RS,GT4) – XL Front 2-Piece Complete Lower Control Arm Kit – Pair of 2 (See LCA Fitment Notes)

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

The RSS Tarmac Series XL (Extra Long) Front Lower Control Arm Kit is engineered for Porsche® 987, 997, 991 (C2, C4, Turbo), and 981/982/718 models, offering maximum adjustability and performance for aggressive, lowered setups. The extended-length design is ideal for applications requiring additional correction in suspension geometry, particularly on vehicles running increased negative camber and reduced suspension travel.

Specifically developed for motorsport use, this system features tall, adjustable hydraulic thrust arm bushings paired with spherical monoball ends to eliminate deflection and maintain precise suspension control under load. Compared to OEM components, the XL design provides increased range for geometry tuning while delivering sharper steering response, improved stability, and enhanced driver feedback.

Kit Includes:

• Tall adjustable, 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 geometry correction and adjustability
• Optimized for lowered vehicles with reduced suspension travel
• Eliminates rubber bushing deflection for consistent performance
• Improves steering precision, front-end grip, and stability
• Allows fine-tuning of suspension geometry via included shims
• Motorsport-grade construction for strength, durability, and serviceability

Performance Benefits:
Factory suspension components prioritize comfort by using rubber bushings that absorb noise and vibration—but at the cost of precision. 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. The result is reduced driver correction, increased confidence, and superior performance in high-demand driving environments.
