BMW E81 / E82 / E87 / E88 1 Series & E90 / E91 / E92 / E93 3 Series Adjustable Rear Upper Control Arms with Monoball Bushings 2005 - 2013

Upgrade the rear suspension of your BMW 1 Series or 3 Series with these premium adjustable rear upper control arms featuring high-performance monoball bushings, precision CNC-machined from billet aluminium and bearing steel for superior strength, accuracy, and long-term durability. The factory rear camber arms are designed for comfort and reliability — built from stamped metal with spot-welded construction — and are only suitable for daily use without offering camber or toe angle adjustment capability. These adjustable control arms replace the factory rubber-bushed units with M3-inspired monoball bushing technology, delivering sharper handling, more immediate suspension response, and full adjustability for camber and alignment tuning. Engineered as a direct OE+ quality replacement and finished with anti-rust anodized treatment for vibrant color and long-term corrosion resistance.

Features:

• Lightweight and durable construction – CNC-machined from billet aluminium and bearing steel for superior strength-to-weight performance and precise dimensional accuracy
• CNC machined precision – ensures perfect fitment to factory mounting points with no modification required
• Anti-rust anodized treatment – main connecting rod structure is anodized to improve corrosion resistance while delivering a more vibrant, premium finish
• OE+ quality monoball bushings – each arm incorporates a single-ball bushing with dust cover and self-lubricating design for extended service life compared to bare monoball alternatives
• M3-inspired performance design – takes direct inspiration from the M3 control arm geometry, replacing factory rubber bushings with high-performance monoball technology for sharper handling response
• Fully adjustable structure – provides camber and toe adjustment capability for performance alignment, lowered suspension setups, and customized handling characteristics

Contents:

• 2x Adjustable Rear Upper Control Arms with Monoball Bushings (Left & Right)

Benefits:

• Billet aluminium and bearing steel construction delivers significantly higher strength and stiffness compared to factory stamped-metal arms, eliminating flex under load and improving suspension precision
• M3-inspired monoball bushing geometry replaces compliant rubber bushings with rigid spherical bearings, sharpening turn-in response and reducing rear-end deflection during cornering
• Full adjustability enables proper camber correction on lowered vehicles, custom alignment specifications for track use, and precise tuning for tire wear management
• OE+ quality monoball with integrated dust cover and self-lubricating design provides extended service life and reduced maintenance compared to bare spherical bearing alternatives
• Anodized anti-rust finish maintains structural integrity and visual appearance over long-term exposure to road conditions, salt, and moisture
• Low NVH increase – delivers performance handling improvements without the harsh ride quality typically associated with full-bearing suspension components

Installation Notes:

• Vehicle wheel alignment is strongly recommended immediately after installation – adjustable control arms will alter rear camber and toe specifications
• Professional installation is strongly recommended – rear suspension component replacement requires proper torque specifications, alignment expertise, and suspension knowledge
• These arms are designed for performance handling and alignment correction – they are NOT designed for extreme camber adjustment commonly known as "stance look" setups
• Driving with extreme negative camber ("stance" alignment) is dangerous, accelerates tire wear, compromises vehicle handling stability, and is strongly advised against
• Compatible with non-M variants only – will not fit BMW 1M or M3 chassis which use different rear suspension geometry and mounting points
• If unsure about compatibility with your specific BMW variant or chassis code, contact our team with your year, model, and chassis code (E81 / E82 / E87 / E88 / E90 / E91 / E92 / E93) before ordering
