Adjustable upper rear suspension arms for competition, VAG PQ35, MQB/MQB EVO

034-401-1022 - 034Motorsport Motorsport Adjustable Rear Upper Control Arm Pair – VW & Audi PQ35 / MQB / MQB EVO

The 034Motorsport Motorsport Adjustable Rear Upper Control Arms (Ref. 034-401-1022) are designed for Volkswagen & Audi PQ35, MQB, and MQB EVO platforms. They allow for precise adjustment of rear camber, essential in competition, on track days, or on heavily lowered vehicles, while advantageously replacing the OEM stamped steel arms and rubber bushings.

Key Features

• Billet Aluminum Construction, black anodized, much stiffer and more durable than the original stamped steel arms.
• High-quality spherical bearings with self-lubricating Teflon lining, for zero deflection and perfect geometry maintenance.
• 100% Spherical Design: no rubber, no play, no unwanted movement under load.
• Adjustment range of approximately 5° of camber (approx. –2.4° to +2.6°) in addition to the range offered by the stock eccentric bolt.
• Very fine adjustment: adjustable thread in 1/36" increments, each 1/36" corresponding to ~0.18° of camber.
• Dust boots included to protect the spherical joints from splashes and dirt.
• Total elimination of bushing deflection: geometry maintained even under heavy cornering, hard braking, or significant lateral load.
• Plug & Play installation as a direct replacement for OEM reference 1K0 505 323 N.
• NVH (Noise/Vibration/Harshness): medium level: suitable for sporty use, track days, and performance-oriented projects.

Usage and Benefits in Tuning

• Allows for precise rear camber adjustment to optimize grip, tire wear, and cornering stability.
• Ideal for lowered vehicles, aggressive wheel/tire setups (hellaflush fitment), or track cars requiring additional negative camber.
• Eliminates the float caused by the stock bushings, for more consistent and predictable handling.
• Perfect for “track junkies” who want stable geometry, as well as enthusiasts looking for very negative camber for an extreme look and handling.
